Regular non-magnum Tula/wolf primers are prone to piercing. They're just thin. Try the magnum primer, it's not any hotter than a BR4.Thanks for follow up. Shot some CCI 450's this afternoon in 6xc with Palma brass-didn't see any real improvement. Don't understand Wolf SRP piercing with load of 38.6 H4350. I think-looking at case heads-that this isn't a particularly hot load. BR 4, Berger 105'hybrid jumped .005. May move on to large rifle primer Norma cases to see if things tighten up.
Undecided. Will shoot first match of season tomorrow, see from there.
Again, thanks for doing the search.
