Home Forums Hunting & Shooting Ask The Gunwriters Who would not shoot moly coated bullets

I like moly for some situations.

I've had good luck with moly, when used properly, extending throat life considerably. 3-5 times, perhaps more. That is, though, when used properly.

On the other hand, trying to work up loads and test a variety of bullets, moly is a pain in the ass. A lot of the bullets I like to use do not come pre-coated. Coating 250-500, with the equipment I have, is not bad, but trying to only coat 100 is frustrating. The mass of the extra bullets makes the process go more smoothly.

For me, moly worked out better once things were up and running in a sort of production mode. One gun, one or maybe two loads, then moly was fine.

Particularly for target shooting or varmint shooting where I was packing 50-100 round boxes of ammo. I don't like packing a couple extra moly coated shells in my pocket as I do when I'm hunting. Messy.

Moly requires a change in gun cleaning procedures to work properly. Lot of people can't make that change so moly fails for them.

My best successes with moly have come with a 7mm STW where I shot home-coated 120 grain ballistic tips and home coated 160 grain partitions and in a .220 Swift where I shot only home coated 50 grain ballistic tips.

When I sold the Swift, I assumed it was nearly shot out. I wanted something else. The guy who bought it took it to a rifle builder. They ran a bore scope through it. Then called me to find out what was wrong with the gun. They said, based on the rifles the 'smith had built (MANY), that it appeared to have had around 200 rounds through it. I'd put over 2000 rounds through it, almost all coated 50 grain noslers over 43.5 grains of H380 at 398x fps. Not a mild load, in other words.

Actually, what the Norma article on 6mmBR says about throat erosion is this: "When it comes to increased barrel life statistics start to get a pain in b- - t. It is too much a work with too many variabels to do enough tests."

I short they have no idea. The article goes on to describe a group they shot after 10,000 moly rounds through a barrel, but there was no comparison between that and 10,000 rounds of non-moly bullets through an equivalent barrel.
