So far shooting the 156's I have no issues with stabilization 1/8 twist. I just need to get the load dialed in. I also found that my RCBS seater won't even grip my 135 Berger's correctly. It leaves room for runout not that I've tested my loads for this but if it could be induced by the bullet seating stem there is the potential. I've never had as much of an issue with 135 or 140 with overall all length/bullet seating being so drastically different using my seater die. Usually 2 thousandths difference, that didn't seem to manner that much. But with the 156 I'm seeing up to 8 to 10 thousandths. Which is I think is causing enough inconsistencies to change groups. Also mulling back over my target RL 26 does like to be close to max charge for giving better ES and SD I believe.
