Chrome lined barrels are rigid and most of the time not as accurate as good stainless barrel.
Chrome moly vs stainless steel barrel accuracy.
Steel is alloyed with other metals like nickel and chrome as well as other non metals such as carbon sulfur and silicon.
That said chrome moly barrels can be just as accurate when made correctly and there is evidence a chrome moly barrel will hold its.
The highest grade of each series of steels carbon and stainless respectively.
First let s have a discussion about the chemical elements of each material and how their properties effect barrel life accuracy and cost.
Typically the answer to the question all depends on what you as the shooter are going for in your intended build and its application faxon only uses 4150 or 416 r steels in its barrels.
Faxon is often asked which barrel material we d recommend for a given application.
Most ars have these barrels unless they are topped with a stainless bull barrel.
It is also easier to apply a fine hand lapped finish to a stainless bore.
Stainless is easier to machine because it is slightly softer.
The fella at brux told me that the chrome moly was every bit as accurate and the only real difference he knew of was that a stainless barrel craps out all at once when its usable life is over with and that a chrome barrel will gradually go away and not all at once.
Over 90 of high grade match barrels are made from stainless steel.
Accuracy wise perhaps 99 of barrels used in competitive br are ss if there was any.
