yep, like i said i got case seperation at 6, i'm going to try just neck sizing and see how i do. i'm been trying a 41.2 gr load and 42.5 gr load. the 42.5 grain load i'm shooting barely off the rifling, so i'm definitely upping the pressure. i've shot up to 43.5 grains but that wouldn't hold together out to 300 yrds.

how loose are your pockets? are you hand priming? i'm using my hornandy press so maybe i'm not picking up on the pressure difference needed to seat them. they all seem fine to me, never had one fall out even shooting up to 43.5 grains.

i'm shooting H4350 as well and using berger 140 gr VLDs
