Need's ya'll .02 on this matter.
I just got my MPA Matrix Pro 6GT on Friday did some loading at found out it liked this load of Varget with 109's the best. I'm not an expert shot by any means the one small group was a shear fluke lol I average the other two maybe a little smaller with my other rifles. My Velocity was from inconsistent across a few strings and my SD's were like 15 for each string. But these are my groups I shot 5 at 200yards (Max range) and they all stacked into a nice SUB-MOA group without any issues. I'm not a pro PRS Guy just regional matches. I'm thinking it might be the primers maybe? I was going to load same load with my CCI BR-4 and Federal AR Match that I have to see if that helps. My Labrador though was kicking mud butt still working on getting used to using it would not pickup a lot of the shots was only getting like data on 2 or 3 of the 5 if that so I think it was moving because of my muzzle brake or rocking on the bench. All shots were at 100yards with bipod and rear bag today its 54f little wind, but misty.
I measure the OAL of the bullets today they are from 1.270 to 1.289 big difference from Bergers
Load:
Varget 34.0 (Auto Trickler v4)
Berger 109 (Meplat Trimmed)
COAL: 2.605
Lands: 2.620
Jump: .15
Alpha OCD Virgin Brass ( resized it before loading)
Remt 7 1/2 BR Primer
