Bill A. and ThunderBeast Suppressors have done some initial testing with the Ultra series cans on 6.5 Grendel.
The 5" Ultra seemed to be the quietest overall when taking the ejection port area and gas vent holes into consideration, since the 7" builds more back pressure. The 7" Ultra of course is more quiet at the muzzle, but louder at the bolt carrier gas vent holes.
Also, a 30 cal can might be the better choice for gassers since the 6.5mm Ultra's are so efficient, they build more back pressure in a gasser, causing more ejection port supersonic gas escape noise.
This is the can I wanted as soon as TBAC revealed the Ultra Series last year. At 7.4oz, you don't even notice you have a can on the end of the rifle.
If you are worried about repeatability, Ray actually won Steel Safari taking off one of their cans in between each stage, where you have to traverse rough terrain between stage locations, then make hits at long range with a precision rifle. Just to be able to place in the match with a rifle intact is one thing, but to remove a suppressor from the barrel after each stage, carry the rifle over distance, re-attach every time, and win the match is simply unheard of.
