Easily the best load for mine was 24.5g N530. I get about 3340fps with that load. This load will group in the 3s or 4s.
Here is the latest group I shot recently at 200 yards. The top group (bottom a different bullet). 0.6 inch at 200 yards. Hornady brass.
Here is a target that I shot at 100 yards with the same load. Top 0.466, bottom 0.460. Bottom target (shot at right was from clean barrel, other 5 into 0.460)
Pick up some VV N530- I think you'll like it.
