Matt Kline Shoots 2.815″ Record at 1000 Yards with 300 WSM
September 12th at the Original Pennsylvania 1000 Yard Benchrest Club (Williamsport) range Matt Kline set a new 10-shot Heavy Gun World Record with a 2.815″, 100-4X.
Breaking the 3″ mark (for 10 shots) is big news in the 1K benchrest game. The existing IBS 10-shot, 1000-yard record is 3.044″ set by Joel Pendergraft in 2009, while the NBRSA 10-Shot, 1000-yard record is 4.322″ set by Dave Tooley in 2006. Counting this 100-4X target, Matt also set a new 6-Match Heavy Gun Score Aggregate of 99.000. With Williamsport Match 10 still to shoot, Matt could push the HG Score Agg even higher.
Record Set with 300 WSM and 210-grainers
Matt Kline shot a 300 WSM with 210gr Berger VLD bullets. This confirms the accuracy of the short magnum, which may prove to be the new “go-to” cartridge of choice for those who want to shoot the high-BC, heavy 30-caliber bullets. Matt’s gun featured a BAT action, 30″ Broughton barrel, and a Nightforce 8-32x56mm BR scope. The rifle was smithed by Mark King Rifles.
Matt shared some details of his reloading process with Assist. Editor Jason Baney. This may surprise you. Matt anneals his 300 WSM brass after every firing. The necks are turned to .0135″ wall thickness for a .338″-neck chamber. Interestingly, Matt does not meplat-trim or point his Berger bullets. However, he pre-sorts the bullets very thoroughly, segregating them by .001″ variance in both bearing surface and overall bullet length. You need extremely consistent bullet-to-bullet BCs to shoot record groups like Matt did.
