Do any of you know if most Browning rifles work good close to the lands or away? I have a B-70 in 6mm and Ive tried 5 or 6 different loads and different factory ammo, like hornady v-max and the longer bullets just will not group good. Regular old Remington Corelokt shoots beautiful. Are there some guns that just need the jump to stabilize or what else could it be?
