Zeroing in the Wilson 6.8 SPC upper

Took the new 6.8 to the local indoor range to get her zeroed.

I’m shooting Silver State Armory’s 6.8 SPC 85 grain Barnes TSX tactical load. The rifle is a Wilson Combat 6.8 upper (and all their “factory” trimmings), on a Bushmaster lower, with a Rock River Arms 2-stage match trigger. Magazines are C Products 10 round. Scope is a Burris Fulfield II 3-9x40mm on one if their P.E.P.R. mounts.

Allow me to interpret (click on the picture if you want to see a larger version).

I started at 25 yards just to get something on paper, ensuring the scope wasn’t too far out of adjustment. Moved to 50 yards and got things roughly zeroed. Then obtained a new target, which you see above, and sent it out to 100 yards. Starting in the center, the high shot was the first shot. My friend Charles said if you were zeroed at 50 yards you’d be 1.5″ high at 100 yards and that seemed to be the case (given the rough 50 yard zero I had). Adjusted and got the lower shot. Adjusted more and got the almost dead-center shot.

The lower left grouping is then shooting at 100 yards. It’s a 3 shot group. While not the best group, I blame that on operator error. All shots went where my eyes said they went.

The lower right grouping is shooting at 50 yards. If I zero at 100 yards, I want to know where impact will be at 50 and 25 so I can know what sort of holdover I’ll need. So that is a 3-shot group at 50 yards. Looks to be about 0.5″ below point of aim, and I can live with that.

The upper right grouping is at 25 yards. That is a 4-shot group. Looks to be about 1.5″ below point of aim.

I’m pleased. This combination of ammo and rifle is quite accurate. Certainly it will do whatever job I ask of it. And we now have evidence… if I fail to bag that deer or that hog, it’s my fault… can’t blame the equipment. 🙂

  1. Thanx guys. I’m pleased with the results.

    Now I just need to find some feral hogs…

    And I really want to try out that Barnes TTSX 95 grain. I see Barnes is now listing them on their website, and lists them as “6.8” not “.277”, which is pretty cool. Purpose-built is always going to rock.
