[QUOTE="NW Hunter, post: 1230651, member: 23024"] Thanks for the tips guys. I value both your opinions. Fear no wind, I thought it was strange that 58.4 gr had a velocity drop compared to the 58.3 load. 58.5 gr impacted the target at the same height as 58.3gr. Have you seen this up and down in different charges alot? Greyfox, CBTO before sending barrel in was 2.501" with Berger HVLD 140s. Apache milled .004" off the breech to remove "6.5" stamp before cleaning up chamber. New CBTO is 2.497". I used this new figure to put the ogive at .050" off the lands Maybe I should have left new loads at the original CBTO of 2.451"? [/QUOTE]
