I need some help

Hey everyone, I currently have a beretta 1301, k31, upgraded marlin 45-70 and a beretta brx1 in 30-06. I shoot lots and love shooting all my guns, and I also am into hunting, mainly deer and coyotes. Im also a huge gun nut. Im torn on my brx1. Really cool gun, just dont like shooting it at the range since its a really thin barrel and the 1:11 twist means it struggles to shoot heavier loads so . Im thinking of either getting an m1 garand in 308, or a cz 600 range in 6mm creedmoor, or learning to love the brx1. I know they are wildly different guns but I want both but can't finically do that atm. What would you guys do?
