rgh2, unless your gun has very short forcing cones, it will handle light, low pressure loads in 2 3/4" cases just fine. It is much more convenient to load 2 3/4" as compared to 2 1/2". A roll crimped 2 1/2" loads just about like a fold crimped 2 3/4". Unless you are really hung up on shooting 2 1/2" hulls, I'd recommend you use 2 3/4" hulls and the light, low pressure loads found in most loading manuals.
