[QUOTE="Kiwi Nate, post: 366894, member: 8533"] Sorry, hope I haven't left this too late for you. I have done quite exhaustive testing with the VTR and if my tests prove anything, it is that the previous research and tests performed by others towards an optimum brake is correct. A muzzle brake should have its ports at either 3 and 9 oclock or all the way around. The link below is a great insight into brake design and effects: [URL]http://www.rvbprecision.com/shooting/adventures-with-muzzle-brakes.html[/URL] In the VTR, as pressure builds and the brake begins to work, accuracy deteriorates. The effect is worsened with changes to slow burning powders. As an example, Varget was too slow for the .308 VTR I tested (made the brake work) and a faster powder acheived better results- up to a point. Once the brake began to work, groups opened up to 1MOA and greater. The other aspect is the stock, very soft and flexible on both the VTR and SPS.
