so I finally ordered a marlin 1895 gbl despite all the rumors and things ive read online, I would've went with a henry but not having a loading gate is a deal breaker for me. So I already have a mihec 426 GC hammer mold that drops about a 330gn flat nose and a 310gn deep hp pin bullet. it does require gas checks but I was curious to see if anyone has any experience running this bullet without gas checks at a fast velocity, I also purchased a lee 457-450 mold. not a typo, it is 450gn. however it drops at .456 no matter where the temp is or alloy. only alloy I haven't tried is pure lead. so I'm currently in the process of lapping this mold to hopefully drop about .459 or larger. I was also curious to see if anyone has slugged their newer marlins and to see if they have what sizes they've found them to be. ive heard the microgroove rifles are large but have no first hand experience and this rifle isn't microgroove anyway but I'm curious to see. Thanks for any help.
