It is also easier to apply a fine hand lapped finish to a stainless bore.
Chrome moly vs stainless steel barrel.
It is a high carbon content steel which makes it resilient to high heat scenarios and with its abrasion resistance the barrels wear slower over time.
Throats appear to last longer on stainless barrels than chrome moly.
Chrome moly is not lighter than steel but much stronger.
Stainless is easier to machine because it is slightly softer.
Chrome moly vs chrome vanadium is a wash.
That said chrome moly barrels can be just as accurate when made correctly and there is evidence a chrome moly barrel will hold its.
Chrome moly or stainless steel.

Over 90 of high grade match barrels are made from stainless steel.
The common grades of alloy steel have a skooch less than 1 chrome which is way more than is needed to ensure something as skinny as a rifle barrel achieves hardness to the core.
Steel is alloyed with other metals like nickel and chrome as well as other non metals such as carbon sulfur and silicon.
Break in of a stainless barrel is much faster then a chrome moly.
416 r is stainless in name only as it is still susceptible to corrosion but at a reduced pace.
Break in of a hard chrome lined barrel is not possible due to the hardness of the chrome.
On race cars they use chrome moly to save weight by using thin wall tubing made of chrome moly as apposed to heaver carbon steel tubing with the same strength.
A stainless barrel will last longer than an un lined chrome moly barrel but a hard chrome lined barrel will last the longest.
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.
