My 1894 marlin [cas rifle] doesn’t like 200 gr anything, has to be heavier, 225-255, shape doesn’t seem to matter. I load 200 gr for my revolvers. I use around 5.0 gr of clays or clay dot. Lately I’ve been loading for Schofield brass to use in my short bbl .45 carbines. Using up a can of old Bullseye.
