So I’m trying to develop a load for my 6.5PRC rifle.

One of the things I consistently struggle with is primer seating. If the primer pocket is really tight and it takes a lot of effort to seat the primer, then I almost always end up crushing the primer.

If the primer goes in relatively easy, I can feel it bottom out and I seat it perfectly.

My question is this, what does crushing primers do to accuracy and why?

I’m using both Hornady and Gunwerks brass. I run into it with both kinds and it doesn’t seem to matter whether it’s first firing or 3rd.

I’m using Federal 210 match primers.

thanks

I don't have an answer for your question, but I'm curious what trimming pilot you are using? I'm having a tough time finding one (I use the Lyman EZ handheld trimming tool, if it matters).
 
Nothing but Hornady Brass here. Never had a primer seating issue - all consistent, and on my 5th turn using a Lee Primer and Fed 210s.

Bump shoulder .002 with a Redding Bushing die and have yet to need to trim a case either.

If you need to trim, I can't recommend the Little Crow Gunworks trimmer enough - use it on my other calibers.
