Being only a few weeks into my reloading career, I have become very comfortable loading plated bullets in my G39 so far, no malfuctions at all. So I decided to buy a lonewolf barrel and see how it works out with lead bullets. I am wanting to know if it is common for a lead bullet to require an OAL shorter than is listed in a loading manual(Lyman #49). The bullet that I am currently working with is a MBC IDP #4-XD(200 gr rnfp). With my factory barrel, my lead rounds would clunk In and fall out freely without a problem at 1.08, but with my lone wolf barrel I am having to reduce them to about 1.07. If I'm missing any details let me know, thanks in advance. Wanna kill these ads? We can help!
