Steve, my Black Special Target has the 1-10" twist and has the threaded muzzlebrake.
Yes, I measured the barrel twist with a patch and cleaning rod. When I first received the rifle I was very excited as I thought I had a 1-7" because of the threaded end. But no matter how many times I tried it was always 10. It won't shoot the Hornady 75gr factory ammo at all, but I've had really good groups with handloads using 68gr Hornady, and with Nosler 40gr all over Viht powder.
I purchased one off a retailer and was insisted on that it was 1/10. Only when I got it in my hands and measured it after seeing the threaded muzzle did I confirm that it was 1/7, which is the reason I sold mine and am still on the lookout for a 1/10.
Why not take it up with the retailer???
I would not have let them get away with that....Where did that occur if you don't mind my asking?
Ah poop. I wanted to be able to play with some different brakes on a Swiss. Hmmm....what to do now....
See and good gunsmith and have the Flash hider chopped off and barrel threaded to 1/2 x28 tpi "easy peasy"
