My goal here at AmmoGuru is to inform you, not to sell to you, or persuade you to buy something. Personally, I like the process of collecting data and information on most any subject related to firearms. Freedom Munitions has given me this outlet to share what I have learned with you, my fellow shooting sports enthusiasts.
Why 165? Well, any 9mm bullet can be loaded to subsonic velocities, but a projectile under 130 grains, loaded to subsonic velocities may not have sufficient recoil energy to cycle some self-loading handguns. Reliability is further compromised by adding the weight of a "gun muffler" to the barrel of that self-loader. Without getting "into the weeds" the reason is, in most self-loading pistols, the barrel must travel rearwards a few fractions of an inch for the gun to operate. Adding weight to the barrel can "stall" that aspect. So, with a "can" in place the ammo's power level must rise to maintain function.
Two ways to change the power level...increase bullet speed (probably to a level above subsonic thus defeating the intended goal) or increase the bullet weight. In this case pushing the Xtreme 165 grain bullet to the correct velocity was the best answer.
My testing @ 25 yards found the Hush 165's to be accurate.
These five 5 shot groups show a solid performance from the Hush 165 grainers: 25 yards from sandbags with CZ 85B
Chronograph Data from my Oehler 35P. It is interesting that the diminutive G26 nearly made the USPSA's Minor Power Factor (pf) cut, coming in @ 123pf. The CZ made it with the smallest of margins @ 126pf and the 6" tube of the G17L produced 131pf.
NOTE: Power Factor (pf) is calculated thusly: (bullet weight in grains (times) velocity in fps (divided) by 1000 (equals) pf.
Two other things are the result of having a lower pf and those are first less muzzle energy and second less muzzle flip.
Ok, we have established that the Hush 165's will operate most any self-loading pistol. It is accurate, and in the right gun will make Power Factor for USPSA Production competitors. IS IT QUIET? You be the judge. I don't yet own a muffler, but check out this video / audio comparison. >
For me the last piece of the puzzle was will the lower pf (lesser muzzle energy/muzzle lift) of the Hush 165's reliably knock down steel targets? The short answer is yes. The reason is momentum. The greater mass of the 165 @ 126pf is equal in momentum to the 124 @ 135pf! Check these two photos. For those two guys that might "do the math" the calculated momentum shows the lighter bullet being 7% greater than the heavier bullet.
Shots with either load on the "calibration line" @ 15 yards failed to knock down this MGM Targets Popper. But move the bullet impact point up an inch and down it goes.
Given the use of a gun muffler, Freedom's Hush 165's should prove to be an excellent choice for the quiet gun crowd. Couple that with its other performance attributes and it should serve the 3-Gun and USPSA Production gun competitors as well.
