Now with more.. stuff.

It looks a tad off to me, though. Should that stock be longer? Barrel shorter?

I think a slightly longer stock would be in order, but the stock also looks too "chopped off the back of a shovel" to me...

[The Archangel Conglomerate]

It's suppose to have a wide neck diameter for all dat extra powder

Because powder is contained in the neck, as opposed to below the shoulder. . .

[Purpelia]

Maybe he is using the kind of solid propellants used in caseless telescoped rounds. In that case he could well put powder in the shoulder.

Would it be advisable to have the bolt carrier sleeve on my bolt-action rifle (no longer a straight-pull) twist a set of cams into place on the outside of the breech to lock the action?

The bolt is meant to sit inside the sleeve held in place by a captive spring, itself camming into and locking within the breech. It is controlled by a set of camming surfaces within the sleeve that force it to lock once the sleeve is closed over the breech. The bolt would be pressed into the back of the sleeve at this point, with its spring-loaded firing pin locked back on the trigger mechanism to fall once the trigger was pulled and through such the firing pin stop removed.

The process of extraction and ejection would be quite simple, with the bolt face leveling with the face of the carrier sleeve once both were unlocked and being drawn rearward in the action. The ejector, set into the side of the receiver, would simply bounce the empty case out of the right side of the open ejection port, ridding the firearm of the spent case and allowing the next to be loaded in succession.

Seems overly complex, and a solution to a problem that doesn't exist, IMO

It isn't overly complex. Look at a K-31 bolt.

And the K31 is a straight pull, and Swiss to boot. Iirc, you said yours was no longer a straight pull. Really, I'm just not seeing what benefit this is supposed to offer over a simple Mauser/Enfield/Mosin-style bolt.

Instead of being a three-part unit like the K-31 bolt (firing pin enclosure/bolt end piece, bolt sleeve, bolt), it is a two-part unit made up of only the bolt and the bolt sleeve. Rotation of the sleeve would be manual, which would allow for greater control of the locking if the mechanism is a bit gummy and stiff. However, as the bolt itself would be pressed into the cams in the sleeve as it is telescoped over the breech, it would be forced to lock as the sleeve does.

Due to the locking being both at the breech and outside of it, the mechanism would be very strong and resistant to detonation in the event of a barrel obstruction, similarly to how the robustness of the Arisaka rifle line led to their ability to withstand squib loads and other nasty things. However, this design is specifically intended to handle high-pressure loads and is supposed to have been ovr-designed for such RP-wise. Would it work for this, or should I just do something more conventional?

I think you're going to get feeding problems and overcomplexity, without any benefit.

The Arisaka is basically a Mauser copy. It's over-built and able to withstand malfunctions because it's a Mauser action designed for full power European cartridges being used with wimpy Japanese cartridges.

How would there be feeding problems, exactly? The bolt is only retracted into the sleeve body when it is pressed against the breech. After the weapon is fired and the bolt assembly is withdrawn, the bolt itself is again even with the face of the sleeve.

The Arisaka Type 99 is by no means the same firearm as the Mauser rifles of the period. The bolt, although appearing similar at first glance, is constructed quite differently and disassembles in an entirely dissimilar fashion. Its design elements have actually led to it being called "one of the strongest military bolt-action rifles ever made," as it can fire 90,000+ psi squib loads continuously without failure, even with an obstructed barrel (although in that case damage to the rifling can be excessive).

I think I'm just going abandon this idea and instead do some silly adaptation of an overbuilt Mauser action and convert it to a bullpup layout.

I wouldn't really call 7.7x58 wimpy.

Actually, no. It's not really that overbuilt, the metallurgy is just better in key locations. Ackerly tested it against other rifles using high pressure loads, and it performed best, while Hatcher recalls that it was tested at up to 120 000 psi without failure. The American Rifleman, apparently also has bullets, and possible the actual rifle, from a 6.5mm Arisaka that was rechambered, but not rebored, for the .30-06, and which didn't blow up or get damaged.

Rifleman Training program questions
I'm thinking that after soldiers become comfortable basic marksmanship (adjust sights hit target at X range) that I should have the Recruits zero their rifles at the Combat setting (300M) and force them to engage targets at 25, 50, 75, 100, 150, 200, 350, 400, 500, and 600 Meters without adjusting the sights for distance or windage. I'll force them to do the same with optics units on both Zoom settings(2.5/4.5X) as well.
All rifle training will be done right handed only because Conformity and practicality.

However would it be worth while to train both left and right hand shooting with pistols as half of the reason to have a sidearms (especially for pilots and vehicle crews who are quite likely injured in any situation where they need their sidearm) is as an emergency backup.

[Mozria]

What kind of a mechanism is it in which the bolt handle for a bullpup bolt-action rifle is extended by way of an attached arm to being on the forend of the firearm? I know I've seen this before on something. I think it was an AMR, but I'm unsure about that.

This is rifleman training, not spec ops training/shock troops.
I guess that the windage and optics part would be a good final test, but as far as actual battles go, I don't think the wind is going to change dramatically during the battle.
But difficult testing is still good testing.
You should also time them.
They should get a chance to know what sort of terrain they'l be engaging in though.
For shock troop testing, I would stuff them in a casket and open it up in a "battlefield" they have not yet observed.

The Arisaka is grossly superior to Nazi garbage Mauser.

According to the description its a SV-99. Looks like a integrally suppressed, blot action, take down, compact, sniper rifle. Or something like that.
EDIT: I found the page on modern firearms, its a .22 http://world.guns.ru/sniper/sniper-rifl ... v99-e.html

Apparently it's .22 LR and has the best suppressor ever made. I'm really confused by that bolt action though...

It's based on a biathlon rifle.

7.7x58 is not underpowered by any definition, unless you're comparing it to the PTRD or something.
