guys i need some help choosing a long range bullet for my 6.5x47L that is currently being built.it will wear a pac-nor 1-8"twist 3 groove match barrel.i still haven't decided on final barrel length.was thinking around 28-29".i was thinking for ranges from 600-1000 yrds would the newer 130 gr bergers or JLK bullets be the best all round fighting wind,trajectory etc. or would 139's be best. thanks in advance
