[QUOTE="MontanaRifleman, post: 273230, member: 11717"] If those are single shot velocities at each wieght, then you are going to get some deviation in velocity. In other words, If you shoot 3 rounds of 90.5 gr, you might get speeds of 3184, 3198 and 3225 with an average of 3202. And if you shoot 3 at 91 gr you might get 3202, 3221 and 3230 with an average of 3218. Chronographing just one shot at each weight doesn't give you a good picture. Now if those are averages fo 3 shots or more, then that would be odd. You also want to make sure your chrony is set up good with good batteries. On your 93 gr load, I think you'll probably be ok at 95 degrees but that might be pushing it. In anycase, it shouldn't be "dangerous", but you might want to work up to it with some lesser loads just to make sure. [/QUOTE]
