IMR8133 in 28 Nosler

[venatic]

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

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.
