500 grains, paper patch it and a healthy dose of RX7.

Dan , can you get OAL short enough for the Marlin with those 500's?
i just now cast some Lyman 457125's and am going to use them in the Mauser. they are LONG.
Indeed. The reference I made was used in a Marlin 1895 CB with MOA precision. The lever gun platform requires a short radius nose form to function properly.
With smokeless I've had better luck with a flat base rather than cup base....and a card wad helps. Don't twist the tail...cut the patch to allow for about 1/8" overlap on the base and fold it over. Smooth sided patch bullets provide a lot of wiggle room for seating depth...
Brooks Moulds is a good place to start looking.
