Years ago i loaded up some 500gr loads for my Ruger #3 carbine, sore shoulder time! The marlin was nice and i took a 250lb boar with it ,sold all of them wish i didnt! The 45/70 is a great cartridge and alot of fun! If you are into reloading you can hand taylor the loads to some lead with hardley any recoil, but beware its addictive!!
