Thank you for the replies. I think I will play with seating depth in this next batch of reloads and see if that helps any.
I was not chasing SD, I just noticed it after I found the accuracy node after testing powder charges.
I've been using the hornady book oal which is kind of short for my 6.4gr charge, and it definitely puts me into +p territory. I'm going to try the vihtavuori oal as it's longer and their max shows 6.4gr so it might work better.
