[QUOTE="g0rd0, post: 1615764, member: 44168"] Ok, remember rule 1,,, never start at max and never take anyones word. Rule 2,,,,, when starting with new lot numbers back off 5% and work back up. A couple of years ago I got a box of primes, brand is not important, I did not check the lot# and loaded up a box, (with my goto load). Got to the range and bang, stiff opening of the bolt and a blown primer and pitting on the bolt face. I did fire 2 more same results. So yes same brand differant lot can be devistateing. As it turned out useing just those primers with the same bullet / powder combo did jump the preasure into the *** section. After restarting a load development I ended up with a 62.0 grn load to get my 3100fps down from 67.0grn of powder [/QUOTE]
