[QUOTE="rpierce, post: 2024545, member: 20643"] Finished up this sick 33XC for Aaron DeRose. Did full load development and everything for it. This rifle is stupid accurate. Shots 2,3&4 down the rifle measured .328"@100 with a random starting load. I ended up settling on a very mild load of H50bmg with .0015 neck tension and 300 gr bergers .020 off the lands, 2989 fps average. The ES on this load is EXTREMELY low, pic of a 3 shot string w 0 ES. 10 shot single digit was had on more than one occasion. I ended up shooting the smallest group at 580 yds Ive ever shot. .362"/.059 MOA AT 580 YDS. Obviously it won't do that every time. However the rifle is consistently holding 3" or less vertical at 1000 based on the last several groups shot with it. Heres a 3.104" group at 1000 with 1.64" vertical. With this very mild load of H50bmg there is almost zero throat erosion. Haven't been able to measure any in the last 100 rounds. I didn't get bolt click til 7 gr more powder, just to give you an idea on how mild it is. Barrel will easily last 1000 rounds. ZERO recoil on this thing. Reticle doesn't hardly leave the target at 1000. Rifle has the following components: Surgeon 1581 timed to a Triggertech Diamond XLR Evolution, sick paint job by Grant Gillespie @ Viking Armament Brux 32" barrel 9.4 tw Slabbed 5 Port Magnum "Muscle" brake Zero Compromise optic bedded into a Spuhr Mount [ATTACH type="full"]226094[/ATTACH][ATTACH type="full"]226095[/ATTACH][ATTACH type="full"]226096[/ATTACH][ATTACH type="full"]226097[/ATTACH][ATTACH type="full"]226098[/ATTACH][ATTACH type="full"]226099[/ATTACH][ATTACH type="full"]226100[/ATTACH][ATTACH type="full"]226101[/ATTACH] [/QUOTE]
