I recently ordered the Thunderbeast 338BA via the Group buy. Well it arrived to my dealer on Thursday and him being the great dealer that he is we went out and did some shooting today. I attached the brakes to both my R700 in .308, and my AIAW in 338. fired a couple rounds out the the 308 to get zeroed and then threaded on the can. I Pulled the trigger and i swear i could have head a mouse fart. the Dealer not being experienced with Thunderbeast was Blown away. The kid two lans down that was shooting his 10/22 and reveling in the fact he had the quietest gun at the range almost started to cry. I have shot suppressed rifles before, granted they are all my friends and most have been AAC cans, however there is something about the 338 BA that is magical. thinking that it was all that extra volume from it being a 338 can on a 308 we mounted it up to the 338 lapua. and same deal still quieter than the .22 two lanes down. and no concussion. I think i sat for 5 minutes laughing in disbelief. the biggest difference between the two rifles was how fast it heated up. Here is a huge +1 for TBAC.
