I have several questions, I'll try to separate them as to not confuse everyone!! 1-I reloaded 100 Military cases using data from Nosler book #6. #200 CCI primers with 44 Grs. of IMR 4064 and Hornady 150 gr. polymer tip boatail big game bullets. These were set to an OAL of 2.758 instead of the 2.810 described in the manual, this was done in order to use the canalure on the bullet and didn't give it a thought until I was getting ready to load some different bullets in the next group. At that point I realized the 150 gr bullets were seated .427 into the case and the 147 gr. FMJ boatail I was going to begin reloading would only be seated .320 into the case. I would think that this is a MAJOR difference in Pressure! I realize that I didn't use a Hornady book but the bullet is the same weight/shape/and has a polymer tip. Ques. A- After completing the 100 rounds I realized that I had used 15 Magnum primers (CCI #250) in lieu of the CCI #200 which I had used in the others. The problem is that I don't know which 15 they are. Do the magnum primers create a higher pressure? Ques.B- should I have any concerns about over pressure? Ques. C- Does any one have data for the 147gr. FMJ boatail using IMR 4064?
