So yesterday I loaded up 12 rounds of 25-06 varying seating depth per the sticky at the top of this thread. Load is as follows: 58 grains Retumbo New WW brass CCi 200 LRP Berger 115 VLD Results: -0.01 = bad vertical 2"+ group -0.05 = well triangulated 1.5"- 2"group -0.09 = bad vertical 2"+ group -0.013 = first two shots about 0.75" and last shot went very high The reason I started at 58 grains is this rifle shot very well 0.50" out to 500yds with the 117 grain sierra gameking loaded here 0.01" off rifling. This is a safe load with the 117 and 2.5 grains less than max. My question is where do I go from here? Do I start powder development with the -0.013" seating depth, or try jamming the bullet to do powder development and then step the bullet backwards? I'm thinking that due to the vertical I need to increase powder charge. What say you? Thanks ahead of time.
