: About the action work- my 98 Mauser's that funtion with magnum rounds seem to feed this one just fine - as does the .264 magnum Winchester m70(post64) action I used. The Winchester acton I'm using holds 4 rounds in the magazine- a surprise to me.
: As well, I have an old m'71 .43 Mauser that has a .459" groove dia. The rifling is .011" deep, and of course, .439 and .446 dia' bullets were too small to shoot well. I re-chambered it with the same .450Alaskan reamer and shoot Black Powder in it along with Black Mag3 replica black powder. 2F GOEX yields 1,380fps while the BM3, same 505gr. Lee cast bullets get 1,420fps. 45gr. H4895 yields an incredible 1,500fps with low enough pressures for this old excellent condition action(actually the same pressure by measurements as 80gr. 2F gives)
