Moly Coating - Facts, not opinions.

So you need more proof, ok I love a challenge!
Don't take my word for it, read what Norma had proven in their laboratory. This is just a sample of the weight of evidence.

The following text was part of a statement made by Norma on tests carried out on Moly coated bullets. Test was in May 1995.

Firing Norma's standard match ammo ( uncoated) under controlled laboratory conditions, in the 6.5x55 Swedish Mauser accuracy invariably began to fail before 3500 rounds. Direct Quote of Norma technician ," Our experience has shown that accuracy life of these barrels consistently falls within the range of 3000 to 3500 shots". Loss of accuracy always results SOLELY from EROSION in the BORE-THROAT and at the beginning of the rifling.

Norma has contracted an experienced independent shooter who is also a gunsmith, to conduct a barrel life test using their Moly treated 6.5x55 Match ammo. Test barrel was a Sauer 740mm (29inch). This barrel was a run of the mill sample and was not hand picked. To date ( as of May 1995 that is) this test has exceeded 5000 rounds of Diamond Line Reg. ammunition.
(the projectiles in this Black Diamond ammunition were coated by the NECO reg. system supplied to Norma for the test around 1992). see ref. Precision Shooter . August 1995 page 19. Story by Dave Brennan) There is no target evidence of accuracy loss. Further bore scope inspections performed after each 500 shots by Norma's product development technician Christer Larsson, show MINIMAL EROSION in the throat of the bore and at the start of the rifling.
According to Norma, " Several independent experts examined the barrel ( moly test barrel) after the 5000 shot threshold was reached. Without knowing the barrel's firing history. All estimated ( wrongly) that the barrel had been fired approx 2000 times. The test shooter believes that the barrel still has 20 to 25% capacity remaining. Ref. Precision Shooter December 1995 page 12. Written by M.L. McPherson.

Additional required reading riddled with proof.
From such experts as, Merril Martin ( co founder of NECO system); Dave Brennan, Editor Precision Shooter; Chet Whitebread , Kansas Benchrester ( one very smart man); Roger B. Johnston (co founder and owner NECO System); Dave Scott, Technical writer, Precision Shooter; Charles F.

If you read these articles I'm sure you will see that moly bullets do have the potential to increase barrel life and reduce throat erosion.

I knew some of this stuff in 1989, but it was Chet Whitebread (A Genius) in 1997 that really brought it all together and explained why moly bullets shot higher on the target when the same chamber pressures were used . When I saw how simple the proof was I kicked myself all over the workshop. The choice of a title " Bullet DROP Mystery" is misleading it refers to a bullet's trajectory, not shooting lower than another bullet. The moly bullets, in fact, shot higher than uncoated bullets and he explained why. Some writers and experimenters in the early days wrongly concluded that moly caused bullets to shoot lower than uncoated and they did for the same powder load. They did not understand at that time that the powder load needed to be increased in order to achieve the same original chamber pressure, then the moly bullets shot higher.
I had spent a lot of time swaging my own projectiles and thinking about deformation of the projectile during firing, developing my moly process to minimise any damage to the bullet, but I never thought of pushing projectiles through a barrel to see the results and I never had the facilities to catch fired projectiles without damage - although I did try, and failed to recognise the results. I take my hat off to Chet Whitebread.

GS Custom Bullets manufactures solid copper, turned, monolithic bullets for hunting and sport shooting. These bullets are used by hunters on several continents, hunting from the smallest of antelope to the largest of dangerous game, using the smooth HP bullet, as well as the more popular HV, FN and SP bullets with the patented drive band concept. GSC bullets are configured for the highest possible ballistic coefficients. SP bullets are mainly used for sport shooting. All GS Custom Bullets are moly coated.
