Obviously you never have,I findpublished ballistics to be optimistic at best. My chrony hasshown very few loads be it factory orreload datathat meet the statedvelocity.

I agree thndrchicken the only real way is firing them from your rifle over a chronograph and at the distances you intend to shoot. Anything less is only a guess. I have seen 2 identical rifles/loads at different MV's on many occasions, their is more then just powder in a case that factors into the performance equation and the only way to knowis by testing!
