of energy still ensures lethal expansion and penetration on varmint-sized critters while a nongreasy lubricant coating provides flawless operation in semiauto platforms and varied weather. My one unresolved issue is the accuracy - since I really would like to get the same accuracy I see with my 124gr loads. 22 LR load features a 38-grain hollowpoint bullet that’s designed to expand at a lower velocity of 1,037 fps. Now I'm going into mass-production mode and I'll start running it through it's paces in the next few weeks. Overall, I had a lot of fun with this load. With this pistol, we are actually a bit below the Minor threshold for IDPA & IPSC with the slower rounds.Īs always, the Ti-RANT was just amazing - bringing the overall sound measurements down into the mid-120's!Īs with the M&P, I only had 10 rounds left for accuracy testing and, although the XD(m) did better than the M&P, I'm still hoping for better accuracy results in the future. Once again, this load was easily in the subsonic range - even when shooting with the Ti-RANT, which added 31 fps to the average velocity. XD(m) 3.8 Sound Levels (Suppressed using Ti-RANT 9) Unfortunately, the grouping wasn't that great but, I just didn't have enough ammo to see if it was the load, or the fact that I hadn't warmed up yet. I fired a single 10-round group from an unsupported, standing position 15 yards. As usual I was amazed at just how loud an unsuppressed weapon really is - even when shooting subsonic ammo.Īfter the sound level meter & chronograph, I only had 10 rounds left to test for accuracy in this pistol - and it just wasn't enough to get a good idea of how this load will do. On the M&P 9, this load was easily in the subsonic range - yet it is still above the threshold for making Minor at IDPA & IPSC matches. Having said all that, here are the results: As always, the Ti-RANT was just amazing - bringing. With this pistol, we are actually a bit below the Minor threshold for IDPA & IPSC with the slower rounds. Suppressors reduce the sound of shot by an average of about 30 dB(decibels), but they do nothing to reduce the sonic boom that a bullet makes as it flies. the muzzle energy is reduced by a factor of 8 A subsonic 223 round will be quiet with a. An AAC Ti-RANT 9 suppressor was also used with a sound level meter to get some suppressed results. Once again, this load was easily in the subsonic range - even when shooting with the Ti-RANT, which added 31 fps to the average velocity. Bolt action 300 blackout suppressed decibels. The initial testing was done with a 5" M&P and an XD(m) 3.8 with a Storm Lake threaded barrel.
I got a chance to take those initial 9mm rounds out to the range and I have to admit that it was a lot of fun! I only had 50 rounds but, it was one of those times where I left with a smile on my face.
