Any one have any insight where to start with 140gr accubonds for the 270? I'm shooting a remington 760 gamemaster 22" barrel. I've got a great load with 150 gr nosler ballistic tips but I cant find much for the 140 gr accubonds. I have 4831sc, 8208 xbr, varget, 4895, 4350 and 7828. The first 3 are what I have the most of. Thanks!
