I worked up my most accurate load yet with RL17. It is 180 grain accubond with 56.5 grains, CCI 200 primers, and an OAL of 3.41". This load is clocking 2820 fps and is grouping 3/8" on calm days and 1/2" on a brezzy day. This is going to be my hunting load this season.
I tried RL17, Retumbo and H1000 in my 25-06. On the Nosler site, the Retumbo was the highest velocity powder they listed fpr 110 gr bullets. RL17 beat it by about 200 fps in my Sendero. I got 3500 fps with 55 gr/110 AB's and no pressure signs.
It also beat H4350 by 200 fps in my 300 WSM with 67.5 gr/180 E-Tips.
I found the Alliant max loads 1-3 gr light in *MY* rifles.
