Thank you for the offer. I should have been a little more specific about what I was looking for. I am looking for something with 7/8 threads, and a 1.3 or larger overall diameter. But I didn't want to limit my title to that because more .338 shooters than me may be looking as well.
I will probably end up getting one of his, but the model I am interested in is still in the testing phase. Also, I prefer a brake that has the first port venting 90° from the muzzle instead of back at the shooter. Especially with 130 grains of powder
