Finally got to the range. The new GI mags worked flawlessly loading everything 100% when dropping the slide on a new mag. Of the 40-50 rounds fired, I did have 2 failures when loading a round during the full recoil cycle on the large 250gr bullets, so might have to play a little still with the overall length and the main recoil spring.
I tried 2x loads with 185gr JHP - those were not high-pressure ones, and it was more to test functionality. All good there, case expansion was good, no primer problems. GI mags worked perfectly. Basically, this setup works well with the lower-end bullet weight.
Now, with the higher-end bullet weight, as I mentioned above, cycling with the 250gr is not perfect. I tried 3x loads with the 800x at 9.0gr, 9.3gr, and 9.5gr. The fired cases are here left to right in that order (5x of the 9.0, then 5x for the 9.3, and 2 for the 9.5). Yes, after seeing the cases on the 9.5gr, I decided to stop there. At least on this setup, with those soft primers, and the 250gr bullet, 9.3gr 800x is my top, safe load:
Recoil-wise, the v2 comp worked great, even with the top load of 9.5gr 800x. I tried video using a holder for the cell phone, but I goofed and aimed it a little too low so hard to appreciate the recoil and rise. I will try getting video recorded again in the near future.
However, I was able to capture too frames on two separate videos where you can clearly see the "jets" on each of the 3x ports of the suppressor, decreasing in magnitude as one would expect as the pressure drops. This was on an iPhone 8 on "SLO-MO", so not going to capture at an incredible frame speed, but still totally "cool" to be able to capture and "see" this stuff!
Since it is not too bright, I think that if one needed/wanted to "show" somebody what a comp does, this would be a good picture to share:
This second shot from the other video clip is even more blurry, but captured probably at the peak of brightness/flash:
I also shot the larger 250gr on my 460Rowland carbine, and went up into the 10.0gr and 10.5gr range, with 460R Starline brass and also with the 45ACP Federal small primer I used on the 1911: no problems of any kind, no pierced primers, no excessive pressure signs, case expansion was good etc., accuracy with a plain 1x red dot was slightly less than 1" at 25 yards, so this 250gr bullet is a terrific setup for the carbine. And the GI magazines worked 100% of the time with this bullet weight and OL - man I think I should buy 1-2 more of these magazines!
So right now, given the timing issues on my 1911 setup, and pierced primers when shooting the 250gr bullets, I am inclined to stay at the 9.3gr for it, and also consider a slightly lower weight bullet for the next load testing, like in the 200-ish range, perhaps the Lee 230gr TL-TC that I have. That might be a better bullet weight given my particular gun/setup/comp.
