Ken Brucklacher Sets 1000-Yard Score Record: 100-8X

Ken Brucklacher, current President of the Original Pensylvania 1000-yard Benchrest Club (Williamsport), joined the immortals this Sunday, May 3rd. Shooting a .300 Weatherby Mag with 240gr Sierra MatchKings, Ken set a new 10-shot Heavy Gun World Record score of 100-8X. The group size was pretty amazing too. A measured 3.137″, Ken’s ten shots also set a new group record at the Williamsport range, besting the previous mark set 13 years ago by John Voneida (3.151″ and 100 score). Brucklacher’s group is just 0.089″ larger than the 3.048″ all-time, 1000-yard small group shot last month by Joel Pendergraft.

Conditions were good when Ken set the record. It was cool, with overcast skies, and the winds were calm with “the flags still hanging down”. Ken said he “took his time, made sure he was on for every shot.” He pretty much held “on the center of the white patch” in the 1000-yard target. The result was spectacular, as you can see below:

Ken has been shooting 1K benchrest for 9 years, and in the past year his big Heavy Gun has been awesome. This new 100-8X record was not a fluke. Ken’s gun has already shot two 100s in competition. In fact, Ken set a 6-match, Heavy Gun 1000-yard World Record for score with his .300 Weatherby, averaging 98.333. In 2008, Ken’s Heavy Gun shot a 100.0 score in the 8th Williamsport 1K match, a 99.0 in the 9th Match, and another 100.0 in the 10th match of the year. That’s consistency.

Gun Specs: Aluminum stock, Lawton Action, Krieger Barrel
Ken’s record-setting Heavy Gun features a Lawton action in a John Buhay machined aluminum stock. Gunsmith Mark King (Duncannon, PA) built the gun and chambered the 34″ Krieger, 10-twist barrel as a .300 Weatherby Magnum with 0.339″ neck. The record group was set with a windage-adjustable rear rest. Elevation is set with the front rest. Interestingly, when shooting the record group, Ken was “holding dead center on the white patch”.

Record-Setting Load: .300 Weatherby Mag, 240gr SMKs, H4831SC, Fed 215Ms
Ken set the record with a .300 Weatherby Mag shooting 240gr Sierra MKs, seated 0.028″ off the lands. His load was 72.0 grains of Hodgdon H4831sc pushed by Federal 215M primers.

Brucklacher 1000 yard recordBrucklacher used Norma .300 Weatherby brass “right out of the box”. You read that right… Ken set the record with brand new Norma brass with no case prep whatsoever. He didn’t touch the flash holes or primer pockets — in fact Ken didn’t even chamfer the case mouths. This was brand new brass, not fire-formed. According to Ken, he “just added a primer, filled the cases with powder, and shoved in a bullet.”

While Ken does not point his bullets or trim meplats, he did weigh and measure the 240gr MatchKings (base to ogive) before loading. Ken has not chronographed this load so he doesn’t know the velocity. Ken didn’t do any special load tweaking for this record group. However, he explained that he changed his seating depth last summer, going from .018″ jump to .028″ jump. That minor change, Ken noted, “really seemed to close up the groups”.
