[QUOTE="IdahoCTD, post: 1459435, member: 13110"] I just built basically the same rifle I suggested you build a couple weeks ago. My reamers is set up for 215's and has a bit tighter neck then normal. It's a Gunwerks GRB action, Christensen barrel, Stocky's stock (not a big fan of this stock. I would run a McM Game Warden if I didn't have the Stocky's.), Trigger Tech Special, one of my 5 port Beast brakes, and Leica ER5 4x20. I chambered it on fathers day (a present to myself) and bedded it the next week. I loaded 75, 76, 76.5, and 77grs of H-1000 with 215's, 5 rounds of each. I bore sighted it at 100 and shot groups with 75 and 76grs. The 75gr load wasn't special but the 76grs load showed promise. So I moved back to 790yds and guessed at my dope. I shot the last 76gr round I had and hit low. I dialed 2 more MOA and shot the 3 shot group pictured with the 76.5gr load. I did zero break in or load development, just shot it like I normally do. I used the seating depth from my buddies gun I chambered with the same reamer. This was with Peterson brass BTW. So with the 9th through 11th round through the gun it shot a little over 1/4moa at 790yds (2.25").[ATTACH=full]101362[/ATTACH] [/QUOTE]
