Just a heads up.
I once pumped the 35 Remington ammunition out of the magazine. Didn't count them, but they quit coming out. Gave three extra pumps, then as is usual when in a place where shooting is OK, pointed the rifle in a safe direction and pulled the trigger.
BOOM.
Shortly after that I read in a US publication that caution should be used with the 35 calibre in that rifle, because sometimes the last cartridge hangs up in the magazine!
