[QUOTE="Left Hand Dave, post: 2619955, member: 94260"] mgondini, Sorry for the delay getting you the information but life has been crazy lately. The following load has proven to be safe in my rifle but may not be safe in every rifle so as usual start low and work up. Norma .257 Weatherby brass full length resized with Redding .280 bushing in die. 121gr Hammer Hunter. 67.5gr VihtaVuori N-570. Federal 215 Match primers. CBTO using my Hornady comparator is 3.835” which makes the COAL 3.345” and the best I could tell about .016 off the lands. Velocity range for 3 shots was 3354-3376 not a great ES but I can live with it considering no brass prep except trim length and primer pockets. No crimp was applied but I may give that a try just to see what it does to the ES. I have had no pressure signed with this load in my rifle. I started to see pressure with IMR 7828 at lower velocity with the hammers and R-26 with the Blackjacks. [ATTACH type="full" alt="1663328149711.jpeg"]394505[/ATTACH] 3 shots @ 100yds has been a constant load but I need to shoot some longer distances. I have had very good luck on deer sized game with the hammers in other calibers. Plan on taking this to WV this year if I get a chance. [/QUOTE]
