[QUOTE="lotech, post: 2094105, member: 63141"] I no longer have a Marlin .45-70 but had a Micro-Groove version for years. Regardless of the rifling type, best accuracy will likely be obtained using the largest diameter bullet that will chamber without difficulty. This will probably be .459", maybe .460". .457" is probably too small for decent accuracy regardless of the type of rifling. I had good luck with the RCBS 405 flat nose gas check and the Lyman #457193 flat nose plain base, both around 410-420 grains in wheelweight alloy. IMR4198 provided good accuracy, but I used a max. of 33 grs. The Marlin was hard kicker beyond that for me. [/QUOTE]
