I just got my Thunderbeast 30BA and all rounds have been dead on with my can for my AR15 and 6.5x47. I haven't shot my 300 win mag with it yet but will try my 208 amax and 180 accubond loads and report back but I haven't seen any change of POI. My buddy who has several cans and has shot them often for 7 years couldn't get over how quiet my 6.5x47 was suppressed. We were shooting behind his house and could only get out to 350 yards but my 6.5x47 was stacking rounds on top of each other. It was a blast shooting while his wife and all of our kids were 50 yards away in his swimming pool. I had no issues with getting the can too hot shooting my bolt gun but it's just too hard not to heat it up with the AR. I can't wait to get out to the farm and try it out to 1000+. These things are a blast!
