After quite a bit of research, here in the Campfire, Jorge's list, various articles in Handloader, and reloading manuals, I settled on H4350 powder. Using new resized Winchester brass and CCIBR primers, a new lot of H4350 with the 250 grain Barnes Originals and my Magnetospeed chrono, 57 grains gave me 2334 fps, sd-26, es-47. 57.5 grains gave me 2351 fps, sd-2, es-5. I had some loaded at 58 but I didnt even try them, the 57.5 load was so consistent and gave me excellent velocity. Accuracy ran just above 1 inch at 50 yards, with the Magnetospeed on the barrel.
The velocity seemed a bit high out of my 24 in barrel. I double checked the Magnetospeed with my ProChrono and it is correct. Ejection was easy and smooth. Brass looks fine. Rifle was built in 1956.
Now on to the 250 Woodleigh.
