I found a technical note in my 175 long range accubond and 150 long range accubond bullet box it says share load data for Nosler bullets of equal caliber and weight.It also also states when reloading the accubond LR bullet,Nosler balliticians have found the maximum Saami overall cartridge lengths tend to provide best accuracy.
INGWE, what seating depth are you doing. I just spent the day shooting 68grain, 70 grain, and 72 grain Retumbo, c.o.a.l was 3.390. I found so far that 70grain shot the best. It was 1" group at 200yrds. I need to now fine tune it to get down to 1/2 group. I am open to trying other loads to see what works best.
