The new Weatherby's barrels are chrome-lined, a feature designed to improve barrel life
and pattern consistency.
Since that means putting a new barrel on the rifle, we might as well get one that is hammer-forged so that we benefit from longer barrel life
An operator with experience may be able to estimate remaining barrel life
by closely examining the chamber throat, but for most of us a scope is most useful for evaluating our barrel cleaning habits (or lack thereof).
223's--and the smaller powder capacity and longer neck extend barrel life
As a general industry-wide rule of thumb, it is believed that typical barrel life
is, on average, two to three times that of the screw life (with compatible wear resistant materials).
The result of all this is improved cooling and thus a longer barrel life
In addition to the upper receiver requirements listed above, the following information must be provided with any response to this RFR: documentation or verification that upper receiver components currently meet or exceed Mil-Spec requirements, and an estimate of the barrel life
(in rounds) with normal use, by the manufacturer.
Longer screw and barrel life
reportedly result from an unexpected benefit of the new screw assembly.
The place to start a discussion of PTH and laminate problems is with a review of the standard through via, including barrel life
as a function of temperature.
A new barrel erosion indicator gauge, NSN 1005-01-535-5576, now makes it possible to safely extend barrel life
up to 50,000 rounds per barrel or 300,000 rounds per set of six barrels.
The intended barrel life
is 35,000 to 40,000 rounds--twice that of M16-family weapons.
others, experience considerably shorter barrel life
than do the calibers
