[QUOTE="MontanaRifleman, post: 908451, member: 11717"] Here ya go... had a nice day yesterday and shot these groups. I actually shot the 326 yd group first thinking I was on the 212 yd target :rolleyes: The 427 yd group was the third group... put a smile on my face :) This is with the 96 gr load. No more pressure "issues", other than the charge weights are low for the pressure/velocities I am seeing. Based on the results of my initial pressure testing and others results, I believe I am about 4 gr lower on average than what I would consider as "normal" pressure range for charge weight. Fooled around with the 97 grain load on Sat and accuracy was about .5 - .7 MOA from @ 212, 326 and 427 yds and felt I was flirting with high pressure. So I backed it back down to 96 with good results. [/QUOTE]
