I used a same load on my new AT I used on my AW. It's 42.2 of imr 8208xbr. About every ten rounds it has a sticky bolt. No primer or ejector issues. But it is the same on my factory barrel or my bartlein. Is it a problem? I shot the load in the AW in 100 degree weather with no issue. Any help is appreciated.

Could it be that some of your cases have been fired enough times that the case is starting to expand a little?

Kinda my thinking, neck sized?
After 5-6 loadings I get a slightly sticky bolt on a few cases in a lot in my 260.
Yeah, if you're only neck sizing then the base of the casing is expanding and making it stiff.

Do you grease the lugs at all? And how sticky are you talking, just a little more than usual drag or do you have to hit the bolt with your palm to turn it?
I had the same problem. The base of your cases are too expanded. Even if you full length resize. Get a Redding small base die and it should solve your issue.

How far are you bumping the shoulder.
I really doubt a SB die is needed.
Could be a few cases that need annealing, they don't size the same when they start to harden and a few might be getting cranky.
A minor die adjustment might be all that is needed.
According to the Lyman gauge it averages out to 0.0200 I am bumping the shoulder back to make it fit the case guage perfectly. I am using a reeding fl die with bushing. I'm using Winchester brass
