What’s a “wallet group”? It’s a singularly spectacular proof target that entitles its bearer to bragging rights. The wallet group may or may not have been shot in competition, and, by definition, it may not be repeatable. But it exists as incontrovertible proof that, at least once, the stars aligned, and the wind gods smiled on the shooter.
Five Shots in 0.178 MOA at 1000 Yards
A couple seasons back, Forum member and F-Class shooter Gary Wood was testing his 6.5-284 rifle at the 1000-yard range in Coalinga, California, getting ready for an up-coming long range match. In practice, Gary nailed a witnessed 1.859″ five-shot group, with four of the five shots well under an inch. Use this as proof to win those club-house arguments about whether it is possible to shoot “in the ones” at 1000 yards. Gary’s group worked out to 0.178 MOA!
Gary reports: “I was load testing with 5-shot groups. Each group was shot on a new F-Class center and pulled by Ret. Master Chief Jerry Pullens and spotted by an other long-range shooter. The second 5-shot load group looked really small … by our reckoning four out of five shots measured under an inch. I was amazed. What’s more, when I shot the group, the 4th shot blew the spindle out of the 3rd shot. My spotter saw that in his scope and Jerry Pullens told me about it afterwards”.
As measured with the OnTarget Software, using a scan of the target, Gary plotted the group size at 1.859″ total for five shots, or 0.178 MOA. Gary noted: “I had everyone sign the target which I saved and photographed.” Yes, Gary, this may be the wallet group to end all wallet groups. You should have that target framed.
Gary’s Load and 6.5-284 Rifle Specs
Gary’s load was 48 grains of Hodgdon H4350 and CCI BR-2 primers, pushing 142gr Sierra MKs, in Lapua 6.5-284 brass. The rifle features an F-class, single-shot Surgeon action with a Bartlein 5R barrel chambered with a no-turn neck. Gary says “The barrel only has 70 rounds through it… yep, I think it will shoot.” Gary did all of the gunsmithing and barrel work himself.
Did Gary have any special reloading tricks? Apparently not: “Other than weighing the cases and the powder very carefully, there really were no magical reloading secrets used. The Sierra 142s were moly-coated straight from the box of 500, but they were not weighed or checked for bearing surface. The powder was dropped with a RCBS ChargeMaster then checked with an Acculab scale (to under a tenth). The Lapua cases were not neck-turned, but I did weight-sort them. The five cases for the small group weighed: 195.05, 195.03, 195.03, 195.03, 195.01.”
