250 gr Monoflex Bullets

[Hoot]

I got all the tests run, other than aborting some due to being once again reminded that QuickLoad over-predicts W296 and 300 MP powders by a significant amount. Some day, I will remember... I had hoped that like Lil Gun, this bullet would boost pressure and its offspring velocity with these powders as well. It didn't.

Hop, I recommend W296 starting where I left off at 38gr for a 1:24 twist barrel and working up in 1/2 grain increments. For 300 MP, start at 39gr and work up in similar steps. Seat to 2.26 COL. I was using hot Rem 7 1/2 primers. An alternative would be CCI 450's. Bring the heat

It was stiff fingers, runny nose cold (40-45 deg) if testing under hotter conditions go slowly. I'm leaving tomorrow morning to visit my Dad out east so I won't in all likelihood, get a range report done before I return in a week. Next to no internet there without jumping through hoops.

Thanks Hoot, I'll give your recommendations a whirl shortly and let everyone know how they work. Safe trip...
