Just an fyi, there is a suppressor section as well. I'm looking to get a Thunder Beast 338 Ultra myself. I don't own a 338 (may in the future), but want maximum suppression. There are plenty of videos out there that Ray from Thunderbeast does and compares different suppressors side by side as well as Silencer shop videos.
I love shooting suppressed myself. Once you do, you won't want to go back to shooting unsuppressed. Only issue is the extra weight and length, especially with big bore cans. I have mostly direct threads but My Thunder Beast Ultra 9 is a thread over muzzle brake and nice setup. As will be my Dominus and 338 Ultra. Guess first you have to determine your priorities. A lot of cans out there, answer the questions below and will help narrow down your selection.
1-Cost
2-Weight/length
3-Material build
4-Amount of suppression (kind of goes with #3)
If you just want to take the edge off some, want to be economical and concerned about size and weight you could go with one like the Griffin Sportsman Ultra Light weight. With suppressors the more volume the better they suppress typically, but also depends some on the Baffles and build. I guess one thing to add is make sure to go with a well established company with a great warranty. There have been a few companies go under and will probably never get their cracked cans replaced or warranted.
