OK, I have a theory.
I think the bullets that seat hard arent from unturned necks. I think they are from hardened brass. I anneall periodically and find that I dont have any hard seating bullets.
With brass that I have not annealled, even fl resized or neck sized, I find that there are some that are hard to seat. When I anneal, no issues at all.
There is no other data I have to support this, I just have noticed this when I reload.
