Moly coated bullets...

Good evening

This may be a stupid question, but anyway...

I reload my rifle ammunition and to date have always used plain copper-jacketed bullets. I've been offered some moly-coated bullets - if I load and fire these through the rifle, are there any implications for accuracy etc if/when I want to shoot plain copper jackets? Will there be moly in the barrel (I assume yes) and if so does it matter? If it does, how do I remove it?

TIA

Andrew

A few years ago, we all mollied our bullets - the alleged benefits were less cleaning, less wear, accuracy maintained after firing lots of rounds.

Then we realised we lost velocity - not many shooters want that. Barrels still burned out and cleaning became a bit iffy - just when did we need to clean?

So most of stopped using them - which is probably why you are now being offered some moly bullets - I've got a few myself.

There are various theories on moly build-up in a barrel - some believe it, some don't. Read Harold Vaughan's excellent book "Rifle Accuracy Facts'. He didn't believe it.

If you're into accuracy and have a good load sorted - don't bother with a few moly bullets. If you just like to hear your rifle go bang - then go ahead.

Thanks for that, maybe I'll give them a miss (fortunately i was given them!).

A few years back I attended a talk on accuracy by Kenny Jarret of Jarret rifles. He was not a fan of moly. He described trying to clean a bore shot with moly, you’ll clean and clean and get well developed muscles but you’ll never get the moly out. He builds some of the most accurate beanfield rifles in the world so I’m inclined to believe him.

I've seen a bean rifle, but not a beanfield rifle. Are they similar?

Playing Devil's Advocate a bit here, but if you can't get the moly out of the barrel (and I'm not doubting Kenny Jarret at all) - does it really matter? I thought the idea of the moly was to reduce friction between the bullet and the barrel, so couldn't the moly be on the barrel instead?

BTW - I'm still not going to use those coated bullets I was given...

I was always under the impression that if you used moly coated bullets then you would also moly coat your barrel? (therefore there's no incentive to remove moly from the barrel)

Yes, I think that's what I'm saying.
