I worked up loads for a friend's 30-06. Pushing 165 AB's with 63 gr's, compressed, of RL22 produces 3070 fps in his 22" Rem 700.
I was amazed. It would have never worked out that way had it been my gun. Mine would have likely hit 2850 max.
I recall a friends 30/06 that produced about the same velocity from a pre 64 M70 FW barrel but with IMR4350...we were mystified by it all until we had the bore slugged and it came in at a bit over .309 through the grooves.
I used another pre 64 with the exact load Reloder mentions (I believe that RL22 load is listed in the Nosler manual)and it barely broke 2800 fps....I had to drop back to RL19 and work to 61 grains to get 2950 or so.
All of this is a duplication of what some guys were doing with N205 a while back in the 30/06 case.Whether an AI provides a boost in vels seems to depend as much on what barrel you end up with as anything else.
