Just as an FYI to anyone else following this...
I got a chance to test fire this setup today along with my Glock 17 Gen 4.
I tried the following...
Remington UMC 115gr JHP & FMJ
(I knew this was not subsonic, but wanted to see how much difference the suppressor made.)
HPR EMCON "Suppressor Specific" 147gr FMJ
Winchester 147gr JHP (White Box)
Each ammo switch in the can started with a fresh wipe, I looked at the way the wipe fits into the Poseidon, and the way it is designed, even if it tried to expand, it wold have just blown the wipe out the end, so I took a chance and did not prepunch, I was a little nervous that first JHP trigger pull, but was pleased with the outcome.
I started with the 115's both shot straight, made round holes, so I figured both *safe* to test in the can, with a *significant* sound difference between with and without the it (most noticeable on the handgun) still both very loud though which is to be expected, FMJ would rip the wipe in random patterns around a center hole, JHP cut a clean hole in the center < .25 of round diameter. Wet or dry made no difference I could detect with my ears, I have no true audio testing equipment, the round hole I found very interesting...
Blew out the wipe in about 10 shots regardless of bullet form.
So I tried the EMCON FMJ, it was quiet, but for "Hyper clean" it actually seemed a lot messier, with the dry tests leaving carbon dust, a lot of smoke after each round, I was not impressed with the performance, but it was unquestionably quieter. It lacerated the wipe as well, and it failed to cycle the handgun almost every shot was a FTE with return to battery, stovepipe, or a FTE/doublefeed. It ran in the sub2000 but again messy and smokey. Flew accurate and stable, just simply not impressed though. Completely tore up / blew out the wipe in about 15 shots.
The clear winner was the 147gr JHP Winchester, cut almost surgical small holes in the < .25 of round diameter, flew stable and accurate with or without can, unquestionably the quietest of the tested, consistently, cycled both weapons without a single failure through 50 rounds, and I got 20+ rounds out of a wipe. This was a really well performing round, and as fate would have it only 20 per box at Walmart for 50 rounds, cannot beat that.
I did not have my cell, or I would have snapped some shots, next trip I will get pics of the wipes. But in all cases, the wipes performed BETTER with the HP rounds.
I will be buying more of the Winchester for standard use in these two.
And that Poseidon is actually very impressive for its size, but I simply could not tell any difference in anything other than how much carbon spray I got on myself by wetting it....
