i recently bought a 1874 sharps target model and was shooting lino in my buffalo classic to get a large enough bullet using a 300 grain mold. i just purchased the rcbs 530 grain creedmore style bullet. my question is what is the best alloy for making a bullet for this rifle? i dont mind using lino at all,but have range lead,wheel weights and soft lead available.i will be shooting AA5744 smokeless powder not black powder in this rifle.Thanks
