Had been watching for and found some IMR 8133 here locally as I wanted to give it a run in the 28 Nolser.
Loaded a mini- ladder with 197gr Sierra starting 79.5 to 80.5
79.5 3001fps
80.0 3003fps
80.5 3025fps

Shot two of each at 330 yards
Strange but the lower and higher loads hit in a nice little 1 inch group but the middle charge shot 2.5 inches lower but the two rounds were touching o_O

That's kinda weird but rifles do those things sometimes. Personally, I'd have to do the same test over again to see if I shifted on the bench or what. If that middle load has two touching again at 330yds time to start cranking 'em out! :) johnnyk.
