Plinking Loads with 310 grain Cast

Postby Randominator » Fri Jul 12, 2019 10:55 am

I was looking for a good plinking load that would allow me to get some range time in without breaking the bank. I have a cast bullet from a Mountain Mold that I designed for a custom revolver chambered in 45LC. The mold drops bullets weighing 310 grains and measure .453”. I powder coat and size to .452” for my revolver, so I loaded some of the bullets up for my Bushmaster using AA1680.

Loaded to an OAL of 2.110”, my 40 grain load produced the best group of .918” at a velocity of 1875 fps. All rounds fed from a factory Lancer magazine and with a kinetic energy of 2405 ft/lbs, I may try this round on some boar this fall. Barrel was pristine after all rounds were fired with no signs of leading.

A little thump to the plink lol.

Probably about the best cast load I've seen from a AR.
