I am new to reloading and just getting set up to start loading for my 336 marlin in 35remington. I would love to be able to use cast bullets, as it opens up a broad selection of bullets to use other than what is available in jacketed bullets. I have read that cast bullets are not for the "micro-groove" barrels and others say it doesn't matter, and I really don't know who is right. I also have not purchased a manual yet, as I am not sure which one will have good information on the particular caliber I am loading. Have you any suggestions?
