Hello guys. Im wanting to join the long range competions and be capable of shooting close to 1500 yards. 7mm have great ballistics, but the .300 win mag carries far better than the 7mm mag and their are more choice of bullets? My biggest question is what would you recommend and which one if more accuate to shoot? Im never will par take in long range hunting past 500-600 yards on elk, or deer. It will strictly be for steel and a occasional coyote if I ever get that good. thanks guys!
