All I used for years in my HVA .308 (old Speer book Max loads I-4064 w/Mil. cases) then I got a job and started usin NPT 165 PP's. The Speer HC's are very useful in guns w/short mags. due to their short noses such as in Mod. 99's in 284 WIN. I shot a bunch of deer and B bears with them and my dad used the 165's (30-06) on several elk and moose, no problems ever.-Muddy
