[QUOTE="codyadams, post: 1157190, member: 87243"] By 4831 I assume you mean H4831, not IMR4831, IMR4831 would give higher velocities/pressure than the H4831 with the same charge. I don't mean to sound rude or anything...it just wasn't specified and I don't think you said you chronoed yet, and that would be something that would cause it, if you actually were getting 3000fps... I assume you have a good scope that moves 1 moa when adjusted 1 moa?? Even if it moved 1.25 moa when adjusted 1 moa, that would do it... on my app, you should be in the 8.75ish moa area @500, if your only getting 5.5 something wacky is up... How are you ranging your target? Or are you at a verified range? It will be interesting to see what the chrono says [/QUOTE]
