This past summer I bought a beautiful 1965 Model 70 in 225 Winchester. I shot up a bunch of factory ammo and did some case prep work on the empty brass. (Had to anneal them because I was getting a lot of neck splits.)
I tried a recipe of H4895 with 52gr Sierra HPBT bullets, but didn't find anything real encouraging. A guy from another forum sent me a copy of an old article on reloading for the 225 that included very good results with IMR4320. This past weekend I finally had the time and weather to put a few loads together and do some testing. I only shot the first two strings, but I'm encouraged.
