So I've been having some issues for a while with a 6mm-06.
I used to shoot it quite a bit. Put it up for several years, and when I got back out. It was blowing primers. Checked everything I could. All I found was some light rust in the chamber. Cleaned it, backed loads off 2 grs. Still blowing primers.
After that I took it to a gunsmith who checked headspace, cleaned everything, and re-crowned the barrel. Brought it home this week. 2nd shot it blew a primer.

So if anyone could run a check on Quickload, for a 6mm-06, 105gr amax, and Reloader 22 powder. I'm using Winchester LRP, and Remington Brass. I would appreciate. Just give me a range to work in.

Thanks for any help.

Check with Med River.

It doesn't include RL22 but you might enjoy this article by John Barsness. 6mm-06

Is that a forum member?

Yes.

Reloder 22, like many powders, can vary some from lot to lot. Are you used the same batch?

Also, if you found "light rust" in the chamber, there was probably light rust in the bore--which can indeed change pressure....

I have read that before, and saw a little difference on some other powders. Normally I'm not up near max, so I check a group out of a new jug and keep rolling.
Unfortunately, I have no clue on the RL22. I bought 7, 1# jugs all on the same day. I think 5 from 1 store, 2 from another. They have a different label style so those are easy to separate.
But the other 5... I've moved housed and things happen.

I'll go ahead and say. I used to run 52gr, and brass only lasted 4 loadings. So probably hotter than it needed to be.
It is currently blowing primers out of the head at 49gr.
The gunsmith had the barrel off, and says it is clean with his borescope.
I've not used this guy before. I wish I could send it to Lee, but last we talked, he was retired.
