Had a T2 fitted to my 7mmRM TikkaT3 a couple of weeks ago by Scott Trail of SSRNZ. Test fired it on Sunday and have to say I'm very impressed. Certainly knocked the recoil down to where I will be able to observe hits myself. An unscientific estimation puts the felt recoil at about the level of my 243 shooting 100 grain projectiles at 2900 fps. This is from my 7mmRM launching 162 grain SST's at 2970fps. The muzzle blast is as you would expect significantly increased, but ear plugs prevented any ringing of the ears. I would have no hesitation recommending both the Terminator T2 brake and Scott of SSRNZ. Scott turned the two 7mmRM's around in six days as promised. Am seriously considering having Scott fit a T2 to my Winchester Coyotee in 308 to improve the post shot sight picture.
PS - have now ditched the Limsaver pad on the Tikka for the original Tikka factory slab of rubber (less bounce of the shoulder) and the rifle still sits on target after the shot.
