    hello all,

    so about every 5th wolf primer i seat into my prvi brass using my hornady hand primer, i end up with a little half moon shaving of brass. normal? i had some start up issues with this hand primer so i just want to be sure.

    by the way, the 700 shot a .3 moa group today using 41.7gr of varget. its good to reload.:) average is still about .5, but you gotta love the littler ones

    Was the brass crimped? Poor removal of the crimp can do that.

    negative on crimped brass.

    i do believe the over sized primer story though. shouldnt be a big deal if I continue to use the wolf primers though right? so long as they are consistently oversized? i have 1k of them, so i hope so. and that lines up with how much brass i have.

    thanks all

    Sharp edge of the primer pocket? Primer pocket not chamfered? Hand primer ocasionally not aligned with the primer pocket causing the primer to be shaved on one side?

    I see an issue.

    If you are shaving metal off the side of the primer cup, you are wide open for a primer leaking high pressure gas into the action and blowing yourself up.

    I would chamfer the primer pockets enough to get it stopped, fer sure.

    maybe these pictures would help. i've been through 120 of them, no problems so far. they seat deep enough and go bang every time. but i also dont want to blow up.

    I have the same problem using USGI brass (7.62) and Winchester or Remington primers. I won't use Wolf. It's the result (at least in my case) of overcrimping the primers in. I use a Dillon swager to remove the primer crimp but sometimes in certain lots of brass this happens. It leaves little half-moons of brass all over the table. Just don't use your hand to sweep the pieces off the table onto the floor!:eek:

    I have even gone so far as to increase the amount of crimp the Dillon tool removes to the point of having very slightly loose primers, but I still get little pieces of brass shaving off. If I switch lots of brass it stops completely. Seems to be worst in 7.62 brass but I've seen it in 5.56 as well.

    I have found that prvi brass primer pockets are tighter than w/w or remington on .303 brass.
