Thank you Ray, I'm one who's asked you about the Ultra 5 
This is really good info and I'm glad you tested for Shooters Ear (SE)
30 Cal Ultra 5 at SE 133, 128,134,132,134 Avg- 132.2
6.5 Ultra 5 at SE 127 130 128 128 Avg 128.25
This shows that a can designed for 6.5mm bullets will average about 4db quieter than a 30 cal can, that is surprising (a general rule of thumb is the average person can perceptibly hear a difference every 3 db); however, what is more surprising is how well your Ultra 5 30 cal works with the 6.5 Creedmoor, an average of 132.2 db is really good from that short of a can!
By comparison, you did a similar test at Shooters ear with a 300 Win Mag loaded hot with the following results:
Ultra 5 141,140.5,138.5,140.5,140.5 Avg 140.2
Ultra 7 135,137.25,137.5,138.25,136.75 Avg 137
Ultra 9 133,133.5,133.25,133.5,133.5 Avg 133.35
This shows that a 30 cal Ultra 5 on a 6.5 Creedmoor is quieter than a 30 cal Ultra 9 on a 300WM. Obviously the 300WM packs more punch than a 6.5CM but it helps with understanding how well suppressors suppress when using different cartridges and calibers.
This has now got me back to rethinking a Ultra 5 vs. Ultra 7, I was leaning towards the Ultra 7 but didn't realize the Ultra 5 did so well with 6.5CM...

Thank you Ray. I understand there are many variables to take into consideration. The fact that you'd be willing to do additional videos for the community is a great service to us all. Since I'm on the fence between the Ultra 5 and Ultra 7 that would be great to see how it does with 6.5 Creedmoor with both 30 cal versions, not sure if that was what you were planning but those are the two suppressors in the running right now. When I initially thought of the Ultra 5 it was mostly for my 300BLK subsonic but also for my 6.5 Creedmoor as well when hunting; I did not think the Ultra 5 would suppress the 6.5CM enough for continuous shooting, but your video above showed this to be an incorrect assumption. If the average at shooters ear for 6.5CM with Ultra 5 (30 cal) was 132.2db I will be curious what the avg of the Ultra 7 (30 cal) will be...
Always appreciated Ray. Have the ultra 7 6.5 ordered. Wanting to use it for my ar as well but whenever I get my hands on the 6.5, I might just have for for the .223 and .22!
