Moly Coated Bullets
G'day all,
Anyone use Moly coated projies for F-Std or F-Open? Is it worth it, how much difference does it make, etc.
Regards,
Shaun

It's another variable, cost and job added to reloading. You still need to clean, just less often,wont make your rifle shoot any better, reduces pressure, therefore reducing velocity and your barrel will probably wear just as quickly regardless of whether you use it or not.
I personally dont see the point but if you ask anyone who uses it you will no doubt get a much different answer.
The best way to find out is to try it for yourself and see how it compares to not using it.

I've used moly in nearly all my 6.5 barrels and all showed a slight velocity drop. Some ballisticians say its because there's less pressure build-up due to less friction - others say its because burning the moly lowers the temperature and hence the pressure - maybe its a bit of both. You can usually get the velocity back by increasing the charge - and some say you'll actually get LESS pressure with moly at the same velocity. The main reason I do it is to lengthen the time between cleans - everyone seems to agree this is the case.

Alan,
Thanks for that. I usually only clean every 200-300rds in my kreiger 30cal barrel so only an advantage of cleaning isnt worth it for me. Cheers though, learn something new everyday.
I cant for the life of me remember where I read they can give an increase in velocity.

I've heard that said too, but my own experience is consistently the opposite. Some people in this game don't always use sound methods to come to conclusions. In this case, maybe the velocity testing was done on different days, which even using the same chrono is not always reliable, or maybe it was assumed that velocity was higher with moly because scope elevation "come-ups" were less. There are often other variables at work which are not taken into account, and which can dramatically alter results.

gadget,
sounds like you're a buick man.
giving those bullets a smooth ride down that barrel.
what about boron nitride?
