I have not attempted the 45 Raptor, but have had a lot of success converting s/a c/f to the450 BushMaster. Apache Gun Works and Skinner Gun Works have both built quite a few barrels for me and my friends. Using just factory ammo, they all shoot better than 1 MOA out to 200-250 yards. (Most shoot closer to 1/2 inch at 100 yards). The Raptor might be slightly faster, but I am so satisfied with the 450Bm I just haven't pursued it.
