That said, I set out to find the most accurate load I could with the 240 grain XTP. After a lot of work, I came up with 23 grains of H110.
I don't know when you started useing that load, but i've been useing it since the 70's.. It is very accurate, and i've won a LOT of silhouette matches with it.
I never have to worry about copper fowling though, as i don't and won't use jacketed bullets in my revolvers!!! I won all my silhouette matches with the above load useing a 250 grain plain base SWC bullet i cast myself, and have even taken big game with it includeing moose, deer ect...
Hard cast bullets lubed with ALOX is all i use, and i don't see any reason to change that. In heavier loads, all jacketed bullets do is wear out your revolver faster..
