Cast bullets can be very accurate, as accurate as the best jacketed bullets for sure.

Leading barrels is a combination of things. Speed, temperature, lube, bullet hardness and barrel condition all play in.

If your Marlin is a microgroove barrel you will need 'hardcast' bullets, if it is conventionally rifled most any bullet should shoot OK.

You are going to have to test the bullets you want to use in your gun. Shoot a few and check for leading. Leading near the chamber is usually a bullet that is too hard for the pressure or undersized, leading down the entire bore is usually a bullet that is too soft for the pressure or a lube that is too hard for the pressure, leading at the muzzle is usually a bullet running out of lube or running out of pressure needed to make the lube flow, etc.

It sounds a lot harder than it is.
