    The other screw with the same thread is the "Screw, axis" in a P-14.

    The PVC pipe "gun tub" idea works. Being "tall and thin", they don't take up much floor-space. You can strap them onto the workshop sack-truck / trolley and wheel them around when full. Great for...

    Trail Boss is a "bulky" powder designed for things like .44-40 and .45 Colt.

    It seems to be a sort-of "smokeless" Pyrodex.

    A .308 case has a lot more volume than a .44-40 or .45. Getting a...

    For a given bullet, the lower the muzzle velocity, the faster the required twist-rate. Most .308 barrels are 1:12" twist.
