I have 8lbs of Retumbo so going to run with that. If I could find N570 I would try that as well, but I expect to find a good load with Retumbo.
Had high hopes for IMR 8133 in my 28 Nosler. To date have only been able to get consistent 1" 5 shot groups. Up to 84 gr just over 3100 FPS with 180 Berger Hybrids but without pressure signs in 24" Brux barrel chambered for 195 Berger. Next: Retumbo? H1000? N570? Have considered weight and then bearing surface sorting but sig work and only end up with small number of "perfect" bullets per 100. Any suggestions appreciated.Would like to hear of any reports on using H8133 powder in a 28 Nosler with bullets in the 175 to 195 weight range.

Just came across this thread....here is where I ended up for hunting season:
180 Hybrids, 26" Fierce 28 Nosler, 80.6 / 8133, Nosler brass, CCI-250, getting 3125 avg with 0.7 moa at 200 yds, es ~12. Barrel is at 270 rounds down the tube and cleaned religiously.
Fwiw, shot a bighorn sheep in Montana with the 180 hybrid at 325 yards. DRT. BUT....no exit wound. Looked like a bomb went off inside the chest cavity.
