Ok, I know this is a gun forum but this is fairly related and I just have to mention this. I bought a win model 70 in 7MM WSM less than a year ago and have been really pleased with the cartridge and only slightly less pleased with the gun . That being said, I found a few bullets that shot well, the 145 grain grand slam and the 139 grain hornady BTSP interlock. I liked the rounds but wanted to try the sst's. I got 2 boxes on sale and loved the terminal performance, but they just werent grouping like i wanted. 2 MOA was about it. I heard about the de-resonator and thought it was probably a hoax, I am kind of sceptical. Againt my judgement, I spent 15 bucks on this. Those 2 MOA's shrunch to about .75 and every other bullet shrunk its group as well. This rifle has turned into a good 1.5 (plenty tight enough for hunting) to a sub MOA for all of 15 dollars. I have talked to a few guys that have bought them and noticed only small differences, but my experience has been exceptional. Just thoguth I'd pass it on. EJ

Cool deal. Glad you are pleased with it. I just can't stand the look of it on my barrels[:'(]. But then,I reload for everything anyway and get about as tight groups from my rifles as possible-considering most of them are full customs.
