    I bought a bunch of Bertram Brass for my 338 RUM and have been experiencing some hang fires and a few no fires with CCI 250 primers in front of 100 gr of RL 33 and 285 gr Hornady ELDM. I measured the primer pocket depth and they are on average 6-8 thousandths deeper than the remington brass. I have some Federal 215's to try, but is this extra depth an issue. I always seat to the bottom of the primer pocket, is there a work around? The firing pin strike appears to be normal. Any thoughts?

    First firing with them? I have some 338 edge brass where the base - shoulder measurement was way short. I had to seat bullets into the lands the first firing to expand them enough to fire. Tough brass, but not the best dimensionally out of the box.

    have seen same issue. switching to Fed 215 solved the problem I think the CCI 250 need a harder strike to fire
