I thought you never exceed book velocities? Doing so would be over pressure, right?
Thats rhetorical.

Cratered primers ?

Thats rhetorical.
Yes that is correct. If I am hitting max velocity but at lower powder charge, will go with lower powder charge and let velocity tell me I am in max range assuming other things look ok. Point is if getting higher velocities even with below book max loads, indicative of higher pressures. In this case, the poster was not but worth asking

Looks like he is so busy now that he is no longer accepting orders. We have had him do a couple and it makes like a new rifle. He bushes the firing pin hole and turns the pin to match the hole. No more cratering.
Shooting buddy bought a dasher. Shoots lights out but this happened yesterday. Does this mean he needs pin bushed?

Looks like a pretty good ejector mark on the brass? The crater looks inconsistent?
I think having the pin hole bushed can't hurt but only help. It looks like you are getting inconsistent primer strikes and bushing will help with this too.

Sorry. Started different thread didn't want to hijack this one.
If you to accurateshooter Jerry ( Calsbad) or Paul from Pro Precision I believe is doing bushing bolts now.
I've had Jerry do some for me he does good work and quick.
I've had Paul flute some barrels his work is excellent also.
How far is your buddy bumping shoulders back?
It would be worth checking firing pin protrusion also, if its between .050 and .060 should be fine.
Bushing the bolt definitely could be your problem if everything else checks out.

I don't know on the shoulder. But I will forward the rest of this to him. Thank you!
