Just put a deposit on an older Marlin 444. It has a 24" barrel with their "micro-groove" rifling. Did some searching here and there to see what other folks load for them, most opinions were about which bullet for what animal. Since this is my first experience loading for a lever-gun in big caliber, i'm wanting to try some heavy slugs, Hornady and Speer offer 300 gr. jacketed. Already have a selection of 240, some 265 and 270 stuff. Does anybody have any experience with cast slugs in these barrels? Does a gas-check make any difference?
