I thought I would share today’s TBAC 22S-1 test results in hopes of benefiting the rest of the “Hiders” out there.
The test rifle is a Sako Finnfire Range that was re-crowned and threaded by Adam at MileHigh Shooting to accept the suppressor. He did a phenomenal job and you have to get really close to tell that the barrel is not quite factory stock; it is a work of art.
The scope is a Zeiss Conquest 3-9 with a mil-dot reticle:
Test procedure: shoot two 4-shot groups of various types of hunting (Not Target) ammo, the first group through the TBAC 22S-1 and the second with it removed at 50yds off a bench w/ sandbags. The spotters are 1” spotters.
Group #1 Wincherster HV bulk ammo – approx. 1” POI shift straight up w/suppressor group size about the same.
Group #2 Winchester X 40gr hollow point – approx. 1.5” shift straight up w/suppressor accuracy (precision) MUCH better with the suppressor on.
At this point it was bugging me that the gun was not quite centered up so I moved to spotter #4 and shot some more Winchester X 40gr hollow points to better sight it in. (Of course I way over corrected – see the shot out left). I then made an adjustment and shot a 3-shot group and with and w/o the suppressor on … a consistent POI shift as was shot in #2 (which is what we all hope for.)
Group #3 Winchester X hyper speed (1,435 FPS) hollow points – approx. 1” straight up POI shift with the suppressor on, precision MUCH worse with the suppressor on.
Group #5 CCI Mini Mag 1,235 FPS – ½” POI shift straight up, precision about the same.
Lessons learned:
1. The performance with the TBAC exceeded my expectations. I am impressed with the POI shift consistency of the TBAC – it is always straight up but varies, as I would expect, between ammo brands.
2. Your precision will be affected with the suppressor (at least my .22). In some cases it will greatly improve and in some cases it will decrease the precision of the rifle. You have to test.
3. Note: I also tested Remington Subsonic and Federal American Eagle the previous day and in both cases the TBAC greatly improved the precision. The American Eagle shot better than the small group in #3!
Issues:
There may be an issue where it takes one shot to “warm the suppressor up” before things settle down. This seems to be true with the Winchester X ammo. I also notice that first shot out of my SIG Mosquito with this suppressor is always louder than the following shots. Has any other TBAC 22 owners out there experienced something similar? A lot more testing is required before I can confirm this.
If I get time I will do another test at 100 yards at an indoor range with Match ammo.
Thanks to the great folks at MileHigh shooting and the TBAC crew for making this so much more fun …
