Ran ladder test today with rl17 seated out to 2.945 was about 90 deg out. 43.7 and 44 grouped together and 44.6, 44.9, 45.1,45.4 less than an inch for all four. Think I am going to shoot some groups with 44.4, 44.6,44.8, and 45. If dont see what I want there will go back and shoot 43.6,43.8 and...
Well I finally got out to try it. Loaded to 2.94 COAL and used Ramshot Hunter. 46.1 grains was highest I went and was 2550 fps. Accuracy node was 45.5 grains at 2520 fps. This is with Mcgowen 8 twist 22" barrel.
Finally going to start playing with this, have some free time. I measured wrong first time coal to lands is 2.985 with the 180. So I should be able to go 2.950
I just received new barrel for my rem 700 7mm-08. Is 22" 1 in 8 mcgowen I want to try the 180 eldm in. I was wondering if someone could run quickload to give me idea on what powders might give most velocity.
Thank you guys!!!
