[QUOTE="warboar21, post: 2094378, member: 88146"] I exclusively shoot cast from my 45-70. When shooting cast you need to know what your throat and your bore diameters are. Marlins were notorious for having over sized bores and guys were having to shoot cast bullets of .460 to stop leading and get the accuracy. I’ve heard the newer Marlins are running tighter bores but I’ve not confirmed that. Things you need to do are slug the barrel and ensure your bore is not oversized. If it is then you can either order bullets sized .002 over that diameter or possibly paper patch your current bullet. Depending on how many you have on hand. Paper patching will also alloy you to get more velocity and use a soft alloy as well as help prevent leading the bore. Another alternative is buying powder coated bullets which work like a jacket. That seems to be the most popular method at the moment. [/QUOTE]
