.44mag marlin

[marktattoo]

Just purchased a .44mag marlin micro groove rifling , looking for idea for reasonable rounds to reload, ideally with lead swc or round nose bullets would be idea as one of the ranges I use don’t like jacketed ammo so doesn’t need to be full .44mag power  , any help or tips appreciated

Marlin microgroove rifling doesn't like soft lead bullets so the hard cast bullets from Shellhouse Bullet Co will be ideal. Any published load using Unique is pretty much always going to be good. Its such a forgiving powder its hard to go wrong .

What dies have you bought? First thing to realise is that the American Saami specs for pistols and rifles are different. Pistols are bored 0.429", whereas rifles are bored 0.431" +/- 0.002". Fit is key for cast bullets, so you really need to know your bore diameter by slugging your bore. 1-2 thou over bore diameter is recommended. 0.429" cast bullets caused lots of leading and poor accuracy in mine. I'm casting to 0.434" for mine, although I did have good accuracy and no leading with 240 grain Shellhouse bullets as cast (0.4335") tumble lubed and crimped behind the grease groove because of a very deep throat. Concur with Vince that Unique is a good powder.
