It offers tremendous accuracy and long barrel life, and it hammers PRS steel targets with noticeable effect.
Both barrels are hammer-forged and chrome-lined, so barrel life is excellent.
The efficient use of a relatively small powder charge delivers moderate recoil and portends a very useful barrel life. It has become the favorite chambering among devotees of extreme long-range shooting, along with chassis rifles--like our test gun, the Performance Center Thompson/Center Long Range Rifle
But it wasn't lack of velocity or barrel life that put the .264 on the backburner.
It's mild recoiling, effective at long range, inherently accurate, and provides lots of barrel life. And importantly, it punches above its weight class, providing plenty of authority for most predators, plus deer, antelope, and, with the right bullet and careful shot placement, even elk.
Other potential advantages include improved accuracy, longer barrel life, cooler operation, and less rotational torque.
His creation was blessed with impressive accuracy, respectable exterior ballistics, relatively long barrel life and would fit into a short-action rifle.
The reduced friction also means longer barrel life. Friction and heat are barrel killers, and in addition to less friction, Syntech tests conducted with a 9mm showed 14 percent less heat than a comparable FMJ load.
The new Weatherby's barrels are chrome-lined, a feature designed to improve barrel life and pattern consistency.
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).
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, the reduced heating consistently reduces the point-of-impact shift during high-volume fire, while mechanical characteristics reduce harmonic barrel vibration.
