My nearest neighbor asked me last weekend if I could work up a gallery load for his .375H&H Magnum Model 70 using .375" or .380" round ball (he has both). I said I would work on it using what I knew about making round ball gallery loads - which I have for .30-30 and .30-06 - and my library of loading manuals. So far, all I've found are some vague references to Red Dot and Unique powder generic gallery rifle or low-recoil target loads. Generally, any 30-caliber rifle and 8 grains of Red Dot or 10 grains of Unique and a light, soft lead projectile is considered "the load" for small game and close-range targets. Has anyone ever tried such a project? Any thoughts on .375" vs. .380" RB?
