Interesting...... Page 536 of Speers Number 12 Manual says 8.7 min, 9.7 max on AA#7 for the Speer 180gr GDHP. I looked up Accurates data after you said this and I agree the Accurate Manual that you stated is 7.7 to 8.5...What goes here ???!!!!Kinda dangerous if you ask me, wonder who is right. Chrony records from back then do show 1200 FPS avg. which is high after looking at it a little closer compared to approx 972 in Speers book. I had been having trouble with my old Chrony not working right and just assumed I was getting high readings unfounded.....should have trusted what I was getting by the looks of it. I never got the chance to check the cast boolits, I am betting they will be high also.
