Moly...?

[BoydAllen]

Perhaps for a particular application, short range CF group competition, there is more to moly than is generally known. I attended a match where the person who won the first aggregate, against stiff competition was shooting moly and wax coated bullets, just as Merrill Martin intended. The barrel had 3,300 rounds on it at the start of the agg. It was chambered in 6mmPPC. He cleans with solvent, patches and a bronze brush between each match. He has been doing this since the first articles appeared in Precision Shooting Magazine back when it was printed in black and white and the articles were mostly about benchrest. I just thought that you might be interested in some new data. Yes, his method is unusual but apparently it works. BTW he does not unscrew his brush at the muzzle.

I use Moly for Varmint matches that require 80+ 6mm bullets at 3100 fps+, I used to have fouling issues at 60 rds. The wet tumbling to Moly coat the bullets is a breeze, followed by 30 mins. in a toaster oven to bake the moisture out of the hollow points. The bullets look like jewels. Naked bullets for shorter matches.

The people at Sinclairs several years back did a study on Moly and the effects it has on rifle barrels. They sectioned a couple of cast off barrels and said that under the Moly they saw corrosion liked they'd never seen on any barrel before. A friend of mine that studied chemistry in college said that Moly, atmospheric moisture and oxygen create a corrosive salt when put under pressure. He said a local noted riflesmith did the same test as Sinclair, and found the same results, corrosion underneath the normal fouling found in rifle barrels.
Another report I read was that some rifle teams were tumbling the bullets in the shot only, and were getting better accuracy at extended ranges by doing this. The article said that this is similar to the dimpling effect that makes golf balls fly longer and truer. In that same article it said that a golf ball with one extra dimple extended the range of the flight considerably. It was banned by the golf sanctioning bodies because too many golf courses would have to be modified to accommodate the extended ball flight.

you wouldnt believe what youve missed in 6+yrs. now you gotta anneal every firing, gotta weigh charges to the kernel, do 300 shot load workups, have your custom action trued and damn sure gotta have the firing pin bushed. the older scopes dont hold their settings so you need 2 to check em out, gotta sort bullets by weight, base to ojive length, hollow point hole size and diameter- then when you do that you gotta run em thru a pointing die to get the BC up where you can shoot a little flatter, etc. its a wonder anybody can even make it to the range as busy as we are these days getting ready to shoot.

Interesting info, thx. Wouldn't cleaning the moly remaining in a barrel soon after shooting eliminate the corrosion issue? I guess my query has been discussed/answered prior... Seems that moly bullets aren't made by major makers, but individuals make/coat their own bullets with; for them - excellent results.

Ha! This is a fun hobby, right? I'm thinking it may be Sept before I get all of my varmint rounds loaded. I think I counted 14 steps just to prep each piece of brass, by hand. Ignorance is bliss & I want to remain moderately happy. 3/8" group at 100 -gtg
