[QUOTE="johnnyk, post: 342890, member: 307"] I'm shooting the 180gn Nosler Ballistic Tip with 75.5gn of RL22 and BR2 primers. Velocity during late summer, when this load was developed, was averaging 3160fps and accuracy is sub-1/2". My OAL is 2.9250". I also tried the 180gn SMK with the same load (75.5gn of RL22) but with the Rem 9.5M primer and accuracy was again sub-1/2" (.346"). OAL was 2.8950". I was getting 3133fps from this load. Both of these loads were developed when the temps were running 75-85 deg. I just recently (Nov22) chrono'd the 180 NBT again and velocity dropped to 3093fps, so keep this in mind if/when using RL22. I adjust my ballistic cards to reflect the drop in velocity. JohnnyK. [/QUOTE]
