Lee 379-250-RF powder coated and IMR4895 in a new Winchester 1894 Sporter; 24 bbl ; 1:15 twist.
As you guys can tell, Ive been worried about velocities, as all the data Ive seen have been all over the place.
Loaded increments from the Lyman 4th Edition; 32.0, 32.5, 33.0, 33.5, and 34.0. I only made it to 32.5.
32.0 averaged 1694.8 fps and 32.5 averaged 1720.3 fps. I was shooting for 1400-1600. These were much higher than I imagined. Lyman #4 says min 31.0 is 1408 and max 35.0 is 1752, all from a 30 bbl.
Ive never had to work DOWN! LOL. Didnt shoot for accuracy. Trying to keep from hitting the chrony! I will say the sd was not good as lots of unburned powder left in barrel contributed to lots of variations in velocity. This was the only powder I had on hand to try.
I wonder if the faster twist with the 24 bbl had anything to do with the high velocities, and/or the polymer in the powder coat. Hmmmmm.
Not back to square 1, but definitely moving forward.
