[QUOTE="gohring3006, post: 1440626, member: 78762"] Lots of factors. Load just isn’t quite there. Parallax in the scope, can play a role, but you mentioned the old load shot very well, so that’s out. One thing to consider, SG and twist rates are looked at for stability, but dynamic stability is often the problem, for instance muzzle exit pressure can upset bullet stability, and it probably won’t be noticed at 100 yards, at 500 it will be. This has been observed with certain powders by Doppler, I even read a report where certain types of rifling can affect muzzle release with certain powder/bullets. To shorten this story up, your load sucks for that barrel. [/QUOTE]
