So far my best load has been a moderate one, using XMP 5744 powder and that WFNGC bullet from Ranger Rick. Not that it was a great group, my occasional unexplained errant shot was gone. I got consistant groups.
This started my theory that yeh latch spring is weak. In reading other posts, seem Ferd of canada also arrived at this conclusion. I have some stiffer springs to try, but in the mean time, i have a couple loads with different powders at lower then posted loads. You cannot do this with all powders. the 296/H110 generally dont like it, others are not as much trouble. Once the weather breaks I have a TON of shooting to do. I am actually joining another club tonight to better facilitate all this shooting. The club I am in now is fine, built feel its days may be numbered and its also limited to 100 yards. This new club is well established. In a much better location and has a 200 yard range!!
