Greetings,
Posting some velocity data below, that some might find useful in selecting various host/ammunition combinations for suppressor use: 
Posted values are averages of 5 shots. Other than being a customer, I have no financial or other relationships with the makers of any of the items/brands tested. Also, I have no grudges or other reason(s) to make any of the tests nonobjective. A few takeaways-- - CCI Stingers were indeed supersonic in every barrel length tested, down to as short as 3.3" - For those deciding on an SBR barrel length: 5.5" kept even the hot bulk pack ammo reliably subsonic, but the fastest "fliers" are getting pretty close to the supersonic range. I did not have a 6" barrel to test, but looking at trends in the data, suspect that adding 0.5" more would start pushing a number of shots into the supersonic range. - Between the integrally suppressed hosts: both struggled to keep the high-velocity bulk pack ammo consistently subsonic. The Operative TD did drop the velocity just a tad more, so if you're set on using "hot" bulk-pack ammo, you will statistically get fewer supersonic "fliers" than you would with the MIST (but you will still get some). Hope this info is helpful-- comments / input welcome. SD |

Thanks for posting the data! Any thoughts on why there are isolated large SD variations - Thunderbolts on a 22/45 Lite for example? If the ammo was wildly inconsistent, I'd expect to see the same SD variation across the majority of the different hosts and if the host had an issue, I would expect to see big SD numbers across the different ammo tested. But it seems like there doesn't seem to be a correlation. Just curious.

The only thing I can think of is that they're a bit older ammo than the rest and maybe show a little degradation. I still believe where the average falls out is probably generally accurate, but further testing could probably run this down, if it's important. |
