Bartlien MOD 400, experiences?

[jelenko]

No Sir,
Micron is metric = 1 millionth of a Meter
Not Microinches but more like = 1/26,000 of an inch
(I understand, it can be confusing when they throw in metric with our inch units)
--------------------------------------------------
118 millionths of a meter is equal to .00465"
1 Micron is approx. .000039" or .039 of one thousandth
so 3 x .000039" =?

Well, there you go!

Thanks!

Is this more of a Melonite? rather than Ti Nitride?

Salt bath nitriding. It turns the surface satin black.
The process is also used on small aircraft brake rotors. A surface hardening.

A surface hardening

Mmmm....more of a case hardening since it (hardness properties) goes deeper than just the surface. Depending on alloy it might be .002-.010" deep give or take. The black aspect of it is as you said is more or less on the surface and it can or will wear off with enough use.

I’ve used 3 mod 400 barrels on my 6 dasher and I’m on my 4th. AT 2800 rounds they were still shooting.
