Here’s something you’ve probably never seen before — a liquid-cooled benchrest rifle. No, this is not just a crazy experiment. This gun, built by Joel Pendergraft, produced a 10-shot, 3.044″ group that is still listed as the International Benchrest Shooters (IBS) 1000-Yard Heavy Gun record. Using this water-cooled 300 Ackley Improved, Joel shot the record group in April 2009 at Hawks Ridge, NC. This monster features a 12-twist, 4-groove Krieger barrel. Joel shot BIB 187gr flat-based bullets in Norma brass, pushed by a “generous amount” of Alliant Reloder 25 and Federal 210M primers.

This 3.044″ 10-shot group was a remarkable accomplishment, breaking one of the longest-standing, 1000-yard World Records.

Pendergraft was modest after his notable achievement: “What makes this so very special is to be able to celebrate the accomplishment with all of my shooting friends[.] A good friend once said that records are shot when preparation and opportunity meet. I feel blessed to have personally had the opportunity. The preparation we can individually work on and achieve but the opportunity only comes to a few. Those of you that compete in long range competition will know what I mean.”
