I go to the SAAMI and I see no mention of the 30-06AI. So is Nosler blowing smoke up our ass so they can pave the way screw up this round too? Interestly, in #4 for 180's their max load in RE22 is 62.0 (2985fps) for a load density of 97% - in Manual #6 for 180's, their max load in RE22 62.0 (2985fps) for a load density of 105%. All yo guys know that if you seat your bullet deep enough back in the case to change the load density this much that the ballistics are going to change. I would not trust the new manual for anything but toilet paper. Just shows how arrogant and irresponsible Nosler has become.
If you look at Sierra manual they have same 280AI case and I don't have my Nosler manuals in front of me so can't say what year or manual Nosler was changed to SAAMI spec for the 280AI.
As to the OCL for the 30-06AI they keep the same as for the 30-06 which some like to do instead of special throating.
I guess you haven't read Sierra manual loading data for the 30-06AI as they also have max load of 62gr/R-22 with their 180gr bullets even the long 180gr HPBT MatchKing. I guess you haven't read Speer manual that has max load for the 30-06 with 62gr/R-22 with 180gr bullet as a compressed load also Alliant powder reloading data for the 30-06 has max load for 180gr with 62gr/R-22.
Which manual you using for your 30-06AI?
