Saw this and though it was pretty cool
This July 2nd at the Fifty Caliber Shooters Association World Championships a new World Record was set in Hunter Class with Thunder Ammo & Arms ammunition. We loaded our 802 grain multiband, the TA802XLRB, in RUAG brass with Reloder 50 powder and RWS primers. The 5 shot 1000 yard group, shot by Frank Shinault of Frontsight Firearms Training Institute measured 2.872"!
The rifle was built by Axisworks in Tempe, AZ using a Lilja barrel chambered with my Thunder Ammo Match reamer. The stock they chose is a McRees Precision Big Bore ELR Competition chassis system, a perfect fit for the McMillan single shot Big 50 action.
Frank had run short on ammo, his shooting buddy had the bulk of it in the truck in the pits, and was not going to be able to finish the relay. The shooter next to Frank gave him enough ammo for his 2nd string, leaving Frank with 5 rounds of Thunder Ammo, and no sighters rounds before his final 5 shot string of the day. With those 5 rounds Frank broke the current record of 2.992" set in 2008.
The SD (standard deviation) measured during practice was 1.9, with an AV velocity of 2800 fps. Accuracy begins with consistency, eliminating variables is key, and ending the process by straightening the bullet to case concentricity, or runout, to less than .001 of an inch.
Great shooting Frank!
