I've found that the Reloder 16 Data for the creedmoor is very good on the alliant website. They don't have every bullet listed, but enough good ones to figure things out.
I can't get the Sierra Gamechanger to shoot in my Creedmoor, tried two different barrels OCW from 2500-2900 FPS and all COAL variables... Even when single feeding long ones they still won't shoot. Everything else shoots 1/4". Out of my 260 rem they shoot in the 1's and 2's.
Haven't yet read about anyone getting these things to shoot better then 1 MOA in the Creedmoor, and a lot of people are struggling to get better than 2 MOA. What's the deal?
Include me on the list of not being able to get the Sierras to shoot, at all. They are paper weights now.
I found the Gamechangers shoot great in my Tikka 6.5 using H4350.
Same here. 1/2" accuracy from enough different trips to the range to think it's a 1/2" load. Shoot mine from a Bergara Woodsman with 41.2gr of H4350, CCI 200's, Hdy Brass and a COL of 2.810" Not real fast at 2725 but this load has become my accuracy standard by which all other loads are judged. FWIW: I sent one of those 130gr Gamechangers through a mule deer buck at around 200 yards. Shot just behind the shoulder, broadside - killed that deer instantly. He fell right on his nose flipped over and had all 4 legs in the air. Very impressed with the Gamechangers and am considering using them on elk if I ever draw a tag again.
