Actually, the shot shell does not get pushed back fast enough to get fed to the carrier. It gets jammed halfway between the carrier and the top of the magazine
actually, that measurement is in caliber .177, meaning 17.7% of an inch in diameter. The measurements in ALGODOO, however, are in meters and its sub-categories. so it would be hard to get accurate dimensions XD
And physics accuracy may be taxed if I resized everything. Algodoo does not seem to work well at sub-centimeter simulations unless the sim frequency is increased a lot. I think I'll leave it as is (at least for now. I may try it soon to see how it goes)
