My Semi Auto 45/70!
Posted: 04 Dec 2012 17:25
Ok it's not a 45/70 but it is probably as close as one can get in a semi auto!
16" Carbine 458 Socom Upper receiver on AR-15 Lower. Took just over 2 months to get the upper from RRA. An AR15 10rd mag holds three 458 Socom rounds. and a 30rd Mag will hold ten of them.
My first loads where 405gr Remington bullets with 33grains of IMR 4198. Averaging 1296 FPS.
My 2nd loads where 500gr fmj Hornady bullets averaging 800 fps.
