156 Berger 6.5 PRC

I don't have any experience with Peterson 6.5PRC brass but ADG, Fed 210, and VV N565 seems to produce a very good load for several folks. N565 isn't terrible to find right now either.
 
May have a issue here.
Using Peterson brass 50gr of h1000 got me 2890 fps with hard bolt lift. 156gr Bergers

Running 20 thou jump

Remage barrel set using go gauge and no go gauge. Not my first remage barrel setup.

What measurements can I do to see where my problem is. When chambering a new round it's smooth as butter.
Brass or chamber issue?

Using the hornady comparator tool. Headspace grows .004-.005 on this piece of brass vs new brass.

Definitely sounds like something is off. Hornady app says 50 gr with a 153gr bullet should get around 2700 fps with a 24" barrel. The app's got a max load for that weight bullet and H1000 as 57.4 gr with 3000 fps.
