I run 50gr vMax, which is ok but not as accurate as I have had. The 222 is twisted for 50gr SP max, the vMax works but 55gr did not do well, especially longer bullets with boat tails.
To be honest, the most accurate 222 load I had was my great uncles loading, 50gr flat base soft point, not exactly sure the load but it was developed for the gun, a fully bedded Rem 700. Anyway, 5 shots you can cover all the cut paper with a dime at 100 yards.
I have some 50gr flat base to try again but the vMax work well.
