Recently, I have been experiencing the odd round leaking around the primer seal. I can't find any reason for the ones that leak. Here is what I have:
300Wm 28" Kreiger 1-10"
WW Brass, & WLRM primers
225gr Hor HPBT that I moly with Midway moly coat.
H-1000 @ 74.1 gr. which gives 2865 fps (compressed load)
I did my load work with a different powder lot, & was shooting .192" @ 100yd. But once in a while I would get gas leakage from around the primer with both lots. The primers are not flattened at all, but my firing pin should be bushed as any load I shoot will give cratering with huge radius showing on the primers, while my hunting rifle will flatten them out pretty good with no cratering.
I have dropped my load 2 times, & set the seating depth back also with the same results. Maybe 1 in 20 rnds will leak. And I have marked the brass that the primer seated with slightly less pressure, & those ones have never leaked, while another that seated firmer did. Some have leaked enough to have etched my bolt face, & I don't know where to go from here.
Any help is appreciated.
