[QUOTE="tim_w, post: 1823330, member: 11132"] Thinking outside typical LR hunting cartridges. Maybe look at the 6BR BRX Dasher. They have close to the same bore area to useable powder vol ratio as the 308/7-08/6.5CM respectively and so barrel life. Lower recoil, powder, cost, equal wind.. After all your punching paper & ring'n steel not putting holes in flesh hunting. One thing proven by the F-T/R shooters is anything over 200gr becomes very hard to hold well for 1k. All the top shooters went back to 200x The 105s thru 110s grabbed a couple examples 30" barrel 105 Berger Hybrid 0.005" off lands 30.6 gr Varget CCI 450 3000 fps (similar psi 30.3gr IMR 4895 2905 fps) 1k yd/100yd 1503 fps 7.6"/mph Drop: 26.1 moa TOF: 1.413 sec 110 A-Tip .002 off lands 32.9 Varget BR4 2950 fps 1k/100yd 1574 fps 25.9 drop 6.7"/mph TOF: 1.396 sec Seems to be in the same range as the top 308W and 6.5 CM. With less powder. An improved or dasher would likely equal CM barrel life. Not to mention its something a bit different good or bad as that may be. [/QUOTE]
