Thanks to all for your comments and to Kirby for the great work.
I shot a second ladder today at 200 yards. This is my first real time loading the AMAX if you have any tips that would be great.
I started at 43.8g and worked up to 44.5g I had no pressure signs and the rifle felt good. I want to go up a to 45.5g on the next shoot. I will not go past 46g as I had a primer pop at 47g last time and I am still creeped out by it.
