I shoot a ruger .270. I use 130 grain winchester supreme ballistic silvertips. You don't really need these. Regular remingtion core locks at wal-mart will suit you just fine. For average to modest ranges, sight your gun in dead on at 50 yards. This will also be dead on at 200 yards and 1 inch high at 100. Can't go wrong with this. Whatever you do, stick with the same ammo that you sighted your gun in with.
