I have a Thunderbeast Ultra 9 in .30 caliber. I run it on a 300 RUM, 300 PRC and an AR15 in 5.56. I can tell you on these three rifles I have zero Point of Impact shift with the can on vs. off. I have also taught classes using a companies Thunderbeast cans that were used on multiple rifles. They all had a zero POI shift when putting the can on. My sample size isn't huge, but to me it is significant. By far, I prefer Thunderbeast over everything I have. Yes, it is expensive, but no regrets.
