CHAPTER SIX

BAM!

“Man, I want my bead rifle back!” Julian muttered as his round plunked into the water, well clear of the floating target.

He and Roger stood side by side at
Ima Hooker
’s rail, between two of her starboard carronades. They’d just watched Rastar’s team run through its own training on the schooner’s main deck, and the experience had been fairly . . . ominous. They were due to have their “close contact” contest with the Mardukans the next morning, and it didn’t look like it was going to be a walkover, even with Roger on point. The Vashin cavalry and selected Diaspran infantry who were going to act as the notional “guards” on key defenses of the spaceport would be graded as having light body armor. And since all the Vashin carried at least three weapons, it was going to be interesting.

“You’re just jealous,” Roger retorted as the floating barrel Julian had missed shattered from his own shot. “And it pains your professional ego to be shooting a ‘smoke pole,’” he added with a grin.

The new rifles had been produced just in time for the battles around Sindi, and with their availability, the Marines had, for all practical purposes, put away their bead rifles until they reached the starport. The weapons had been designed using Roger’s eleven-millimeter magnum Parkins and Spencer as a model, but modified in light of available technology.

The Parkins and Spencer’s dual bolt-action/semi-automatic system had been impossible to duplicate, but the base for the bolt form was a modification of the ancient Ruger action, and
that
worked just fine. With the addition of scavenged battery packs from downchecked plasma rifles and various items of gear dead Marines no longer required, the electronic firing system built into the Parkins’ cartridge cases also worked just fine. And since the prince had doggedly insisted on policing up his shooting stands whenever possible and dragging along the empty cases, there was sufficient brass to provide over two hundred almost infinitely reloadable rounds for each of the surviving Marines.

The black powder which was the most advanced form of explosives available on Marduk had made for a few compromises. One was that the rifles’ slower-velocity bullets simply could not match the flat trajectory of a hypervelocity bead, which meant that at any sort of range, the barrel had to be elevated far beyond what any of the Marines were comfortable with. Which also explained why so many of their rounds tended to fall short.

“You can throw a rock faster than these bullets go,” Despreaux growled from Roger’s other side. “I still say that guncotton I made would have worked—and given us a hell of a lot better velocity, too!”

“Overpressure,” Roger commented with a shake of his head. “And it was unstable as hell.”

“I was working on it!” she snapped.

“Sure you were . . . and you’re lucky you’re not regrowing a set of fingers,” Julian told her with another chuckle as he fired again. This time the round was on range for the second barrel, but off to the left. “Damn.”

“Windage,” Roger said laconically as he shattered that barrel, as well.

“Sight!” Julian snapped.

“Care to trade?” the prince offered with a smile.

“No,” the Marine replied promptly, and glowered at Despreaux when she snickered.

While a good bit of it was the sight, most of it—as Julian knew perfectly well—was the sighter.

“Seriously,” Roger said, gesturing for Julian’s rifle. “I’d like to try. I turn the sight off from time to time, but it’s not the same. And what happens if I lose it?”

Julian shook his head and traded rifles.

“It’s going to be a bit tough to zero,” he warned.

“Not really.” The prince looked the rifle over. He’d checked them out when the first of them came off the assembly line, even fired a few rounds through one of them. But that had been months ago, and he took the time to refamiliarize himself with the weapon. Especially with the differences between it and his own Parkins.

Dell Mir, the K’Vaernian inventor who’d designed the detailed modifications, had done a good job. The weapons were virtually identical, with the exception of removing the optional gas-blowback reloading system—which Roger had to disengage anyway, when he used black-powder rounds in the Parkins—and the actual materials from which it was constructed.

It was fortunate that while the Mardukans’ materials science was still in the dark ages, their machining ability was fairly advanced, thanks to their planet’s weather. Whereas industrial technology had been driven, to a great extent, by advances in weaponry on Earth—and Althar, for that matter—the development of machining on Marduk had been necessitated by something else entirely: water. It rained five to ten times a day on this planet, and the development of any sort of civilization with that much rain had required advanced pumping technology. It was a bit difficult to drain fields with simple waterwheel pumps in the face of four or five meters of rain a year.

Production of the best pumps, the fastest and most efficient ones—and the ones capable of lifting water the “highest”—required fine machine tolerances and resistant metals. Thus, the Mardukans had early on developed both the machine lathe and drill press, albeit animal driven, as well as machine steel and various alloys of bronze and brass that were far in advance of those found at similar general tech levels in most societies.

But because they’d never developed electricity, there was no stainless steel, and no electroplating, so the rifle was made out of a strong, medium-carbon steel that was anything but rust-proof. And the stock, instead of a light-weight, boron-carbon polymer like the Parkins and Spencer’s, was of shaped wood.

The weapon’s ammunition was slightly different, as well. The cases were the same ones Roger had started with—as long as his hand, and thicker than his thumb, necking downward about fifteen percent to a bullet that was only about as thick as his second finger. The major changes were in the propellant and the bullet.

Roger’s rifle used an electronic firing system that activated the center-point primer plug, and in the one operation that had been handled almost entirely by the Marines, Julian and Poertena had installed firing systems in each of the rifles created from spare parts for their armor, downchecked plasma rifles, and odd items of personal gear that hadn’t been used up on the trek. Each of the weapons had the same basic design, although each had a few different parts. Mostly, though, it used parts from the plasma rifles, including the faulty capacitors which had made the off-world weapons unsafe to use. There was no problem using them for this application, since the energy being temporarily stored was far below that necessary to cause the spectacular—and lethal—detonations that had forced the weapons’ retirement.

Julian had recommended, effectively, scrapping
all
of the plasma rifles and using their stocks for the base of as many of the black-powder rifles as possible, but Captain Pahner had nixed the idea. There hadn’t been enough of the plasma rifles to provide all the black-powder weapons the company was going to require, so the majority of them would still have had to be made from native materials. Besides, he was still debating whether or not Julian and Poertena might be able to come up with a “fix” good enough to use the energy weapons for just one more battle. Given the probable difficulty of taking the starport, the plasma rifles might be the difference between success and failure, and he’d been unwilling to completely foreclose the possibility of using them.

The propellant in Roger’s original rounds had been an advanced smokeless powder. From the perspective of the Marines with their electromagnetic bead rifles, long-range grenade launchers, and plasma rifles, that propellant had been a laughable antique. Something dating back to the days when humans were still using steam to make electricity. But that same propellant was far, far out of reach of the Mardukans’ tech base, so Dell Mir and the Marines had accepted that black powder was the only effective choice for a propellant.

Black powder, however, had its own peculiar quirks. One, which was painfully evident whenever someone squeezed a trigger, was the dense cloud of particularly foul-smelling smoke it emitted. Another was the truly amazing ability of black powder to foul a weapon with caked residue, and that residue’s resistance to most of the Marines’ cleaning solvents. Old-fashioned soap and water actually worked best, but the Bronze Barbarians’ sensibilities were offended when they found themselves up to their elbows in hot, soapy water scrubbing away at their weapons with brushes and plenty of elbow grease.

But the biggest functional difference between black powder-loaded rounds and the ones Roger had brought out from Old Earth with him was that black powder exploded. More modern propellants
burned
—very rapidly, to be sure, but in what was a much more gradual process, relatively speaking, than black powder’s . . . enthusiastic detonation. While nitro powders might well produce a higher absolute breech pressure, they did it over a longer period of time. For the
same
breech pressure, black powder “spiked” much more abruptly, which imposed a resultant strain on the breech and barrel of the weapon.

Not to mention a particularly nasty and heavy recoil.

Fortunately, the old axiom about getting what you paid for still held true, and the Parkins and Spencer was a very expensive weapon, indeed. Part of what Roger had gotten for its astronomical purchase price was a weapon which was virtually indestructible, which was a not insignificant consideration out in the bush where he tended to do most of his hunting. Another part, however, was the basic ammunition design itself. The Parkins’ designers had assumed that situations might arise in which the owner of one of their weapons would find himself cut off from his normal sources of supply and be forced to adopt field expedients (if not quite so primitive as those which had been enforced upon the Marines here on Marduk) to reload their ammo. So the cases themselves had been designed to contain pressures which would have blown the breech right out of most prespace human firearms. And they had sufficient internal capacity for black-powder loads of near shoulder-breaking power.

In fact, the power and muzzle velocity of the reloaded rounds, while still far short of what Roger’s off-world ammunition would have produced with its initial propellant, had been sufficient to create yet another problem.

The rounds Roger had started out with had jacketed bullets—old-fashioned lead, covered in a thin metal “cladding” that intentionally left the slug’s lead tip exposed. On impact, the soft lead core mushroomed to more than half-again its original size and the cladding stripped back into a six-pronged, expanding slug. The main reason the cladding was necessary, however, was because the velocity of the round would have “melted” a plain lead bullet on its way up the barrel, coating the barrel and rifling in lead. Modern chemical-powered small arms ammunition was manufactured using techniques which were a direct linear descendent of technology which had been available since time immemorial: copper or some other alloy was added to the outside of lead bullets by a form of electroplating. But Mardukans didn’t
have
electroplating, and it was a technology there’d been no time to “reinvent,” so the humans had been forced to make do.

There’d been three potential ways to solve the problem. The first had been to reduce the velocity of the rounds to a point where they wouldn’t lead the barrel, but that would have resulted in a reduction in both range and accuracy. The second choice had been to try to develop a stronger alloy to replace the lead, but since that wasn’t something the Mardukans had ever experimented with, it would once again have required “reinventing” a technology. Finally, they’d settled on the third option: casting thin copper jackets for the rounds and then compressing the lead into them. There was an issue with contraction of the copper, but the compression injection—another technique garnered from pump technology—took care of that.

So the rounds were copper jacketed—“full-metal jacketed,” as it was called. They weren’t quite as “perfect” as Roger’s original ammunition, of course. Every so often one of the bullets was unbalanced, and would go drifting off on its own course after departing the muzzle. But however imperfect they might have been by Imperial standards, they were orders of magnitude better than anything the Mardukans had ever had.

Now Roger cycled the bolt and popped up the ladder sight. The sight—a simple, flip-up frame supporting an elevating aperture rear sight and graduated for “click” range adjustment using a thumbwheel—was necessary for any accurate really long-range work. Elevating the rear sight forced the marksman to elevate the front sight, as well, in order to line them up, thus compensating for the projectile drop. It was another contraption the humans and Mardukans had sweated over, but once the design was perfected (and matched to the rounds’ actual ballistic performance), the Mardukans had had no problem producing it.

But the sights weren’t exactly a one-size-fits-all proposition, because everyone shot slightly differently, if only because everyone was at least slightly different in size, and thus “fitted” their weapons differently. As a result, the sights of any given rifle were “zeroed” for the individual to whom it belonged, which meant this rifle was zeroed for Julian, not Roger. Given that the range was about two hundred meters, the bullet could actually miss by up to a meter even if Roger’s aim was perfect according to Julian’s sight. But there was only one way to find out how bad it really was, so Roger calculated the wind, let out a breath, and squeezed the trigger.

The recoil was enough to make even him grunt, but he’d expected that, and he gazed intently downrange. Although the rounds were comparatively slow, they weren’t so slow that he could actually watch them in flight. But the surface of the ocean swell was sufficiently smooth for the brief splash—to the left, and over by about half a meter—to be clearly visible.

“Told you it was the sight,” Julian said with a slight snicker.

“Bet you a
civan
he makes the next one,” Despreaux countered.
