As far as <font color="red"> MOLY
</font> coating goes, I say yes. It has more going for it than anyother thing I've seen to help reduce pressure and extend barrel life! [img]/ubbthreads/images/graemlins/wink.gif[/img]

As far as I can tell there is no definitive evidence on barrel life - only fouling and initial pressure.
Lilja cautions against using them for barrel break in and he also writes: [ QUOTE ]
<font color="purple"> at the risk of offending those that promote the use of moly, we can't see much benefit to it for a couple of reasons.

I want to avoid a religious debate so I'm just looking for objective/reproducible data, not anecdotes or testimonies.
[/ QUOTE ] Then I guess his shortness has no farther to look than Norma ? Gee, I can not think of why a Barrel maker would not just do anything they could to help you prolong the life of a barrel, what would be there possible motive? Barrel makers are not in the business of selling rifle barrels! I don't sell any of the above, moly or rifle barrels. I do however have a bore-scope and can see the difference in the throats of the barrels that use moly and those that don't! And I do own a bunch of Lilja barrels, why? Because they shoot vary well. I'm only a consumer not a salesman for either side. I know I'm not the only shooter that keeps records on his barrels, or owns a Hawk-eye bore-scope. What does that mean to you? Nothing I hope, find out for yourself! I think there is a easy way to find out for yourself for a cost of just a few thousand dollars. If you already have a rifle set-up for a switch barrel, and own a bore-scope, buy a pair of barrel blanks from a top barrel maker and have them chambered by your smith to the same chamber cut with the same reamer. Shoot the same loads in both (one barrel with moly the other without). Check each bore each time you clean with your bore scope while keeping records of the number of rounds fired in each barrel. Keep a watchful eye on the throats of both. Report back to us at the end of two thousand rounds fired in each barrel your observations. As long as you don't become a moly salesman or a barrel maker then perhaps someone may think your observations are on the level. [img]/ubbthreads/images/graemlins/grin.gif[/img] P.S. I look forward to hearing from you in a year, your reply! Or would this be an anecdote or a testimony??? [img]/ubbthreads/images/graemlins/confused.gif[/img]
