Big, Bigger, and Biggest Bore

Again in 2020, we had a have a look at among the creations of Marco Rigido, the inventive thoughts, and expert fingers, behind the M.R. New System Arms gunsmithing firm. Earlier this yr we had the prospect for a go to to Marco’s workshop and we are able to give you a glimpse of some uncommon large bore tasks.

The A-bore: handheld muzzleloading artillery

You is probably not accustomed to the A-bore caliber; certainly, after we take into consideration the most important gauges from the black powder period, our thoughts might go to both the 2-bore or the marginally better-known 4-bore. Each of those are large rounds, each by trendy and vintage requirements. The two-gauge interprets to a 1.326″ caliber, whereas the 4 remains to be spectacular at 1.052″.

Enter the ball of the A-bore: a 2″ sphere that doesn’t appear to be it could fairly belong to any shoulder-fired weapon. Certainly, if Marco Rigido had positioned the muzzleloading barrel on a wheeled stand, the Italian authorities would have referred to as it a cannon, stopping its authorized possession to licensed residents. However Marco had no intention of doing so, and he made a smoothbore, shoulder-fired rifle!

This firearm (arquebus?) is able to accommodating a spherical payload of both 740 grams of lead (1.63 kilos) or 520 grams (1.15 kilos) of metal, over beneficiant quantities of black powder. Marco did hearth these whereas shouldering the cannon; we don’t have information on the ballistics, however the objective in load improvement is extra targeted on not killing the shooter. We are able to guess that every shot doubles as a reasonably efficient smoke display.

The cartoonishly giant rifle, nonetheless lacking sights and a wood handguard within the picture, permits for a handy storage resolution: it stands up straight if the muzzle is positioned on the bottom.

It’s possible you’ll assume that a big A-bore rifle could also be a bit unwieldy throughout your month-to-month werewolf hunt within the woods, however worry not, Marco obtained you coated! You may have comparable ballistics, and the identical physiotherapist invoice, within the far more carry-friendly bundle of a pistol.

These not feeling courageous sufficient to deal with the A-bore can downsize to the 2-bore, a considerably extra accessible choice, delivering simply 350 grams (0.77 kilos) of lead downrange.

The Cal. 1,000 Bolt Motion Rifle

Leaping onto a extra trendy, cartridge-based platform, we are able to see one other large big-bore rifle. {A magazine}-fed (3 rounds) bolt motion rifle, the Cal. 1,000 can propel a one-inch diameter bullet towards any giant sport, with no threat of missing stopping energy.

The rifle weighs 12.5 kg (27.6 kilos) and its goal efficiency was 2,000 grains at 2,000 fps, sufficient for 35,600 ft-lbs, and sufficient for a stout recoil. Sadly, the Italian authorities killed this challenge (and given the assured DD classification, the USA is unlikely to be a market both), however Marco nonetheless owns the useful and mainly completed prototype.

Conclusions

These are among the most eye-catching creations of Marco Rigido, however a go to to his store might final hours and hours as none of his tasks is typical. Marco can be casually choosing up distinctive designs going from giant bore pistols to revolving shotguns, to blowback .45 ACP 1911, and so on…

Though most of those designs will stay distinctive items and so they might have very restricted sensible use, in a world of risk-averse industrial producers seeing somebody prepared to go in opposition to the circulate is at all times fascinating. Tell us within the remark in the event you agree with such a press release.
