Joel Pendergraft set New IBS 1000-Yard Heavy Gun World Record with ten shots within 3.048” at 1000 yards with this monster gun.

It is water cooled and the barrel is very thick. Based on web pictures of unlimited class benchrest rifles, thick barrels are setting the trend.

Thicker, shorter, means stiffer.

Here is another


That looks lika a pretty handy weapon there... for a crew served weapon
I own to many AR pattern rifles, I guess that would make me a hoardAR

Long Shot, those short, thick and heavy barrels aren't any more accurate than longer, thinner and lighter ones; they're not nearly as stiff as that one. Palma rifle's 30" barrels are longer, thinner lighter ones and they'll shoot under 7 inches at 1000 yards just like the best of the benchrest rail guns do.

That 3.048” group's the smallest one that rig has ever shot in competition. How much bigger all the rest are is unknown to most folks and they'll never learn about their sizes 'cause benchresters' egos don't permit them telling "the rest of the story."

Thick barrels have been the trend in all benchrest rifles for several decades; it's not new. Same for test barrels in Springfield M1903 actions used by arsenals to test ammo for accuracy.
