I just bought a new rifle, and was wondering about moly and film coated bullets. I've read that coated bullets will extend the life of the barrel andaid accuracy. I've also read that moly coatings will "cook" onto the inside of the barrel and destroy accuracy. Can anyone back up either claim? Also, if moly coatings really are detrimental, can the same be said for bullets with coatings like Winchester's Lubalox? Thanks in advance.
Moly was hot several years ago. Even I jumped on the bandwagon. After years of messing with it. I decided to go back to naked bullets. Stuff is messy and time consuming and when you use moly, you can throw out your load books, cause your on your own. You might be able to go up 2gr or mabye even 4gr to get back your velocity.
also for moly to be effective, you have to keep the barrel and bullets coated with it. If you plan on cleaning it out every time, you might not get any benefit. And shot to shot consistency can go down.
I think its on its way out myself. Give it a try and see what you think.
People that seem to use it effectively, do not clean thier guns. They may run a bore snake thru, but thats it. Moly can be hydroscopic like ammonia and I never liked that idea of leaving it in the barrel.
