Re: Some observations about reloading for the Five Seven

In my limited experience reloading 5.7 for my PS90, I have had good results cleaning my once fired brass with simple green and ultrasonic cleaner. I know most of the simple green solution I can readily find is actual concentrated formula, so I use a small amount in the ultrasonic (likely 10% by volu...

Re: HS6 or Longshot?

I have only tried Longshot for my PS90 10" barrel. It worked very well for my firearm, as I got pretty consistent velocity reading from my chrono shooting the 40VMax bullets. I went with Longshot because out of all the info I could find on the web and this forum, it seems Longshot was a power that w...

Re: PS90 SBR reloads with Longshot 40gr VMax

I have a question to ask. I understand the possible risks of shooting my reloads through another PS90 with 16" barrel, that were tailored to a 10" barrel version. I could be facing bad over pressure failure due to the casing ejecting before the bullet leaves the longer barrel. My question is, would ...

Re: Suppressor POI Shift PS90 SBR

Thanks for your input tower. I had installed the FH with mild torque, since there is not much room to wrench. However, I always checked it before shooting. When I took it off yesterday, it still took a good bit of effort with sticking a screwdriver get between the FH prongs to break it loose. The pr...

Re: Suppressor POI Shift PS90 SBR

I talked to Kasey with Silencerco over the phone. He said it wouldn't be a problem if I wanted to send the Specwar back, but if it is purely a end cap strike the performance/accuracy should not be affected. I figured I'd give it some testing the next time I get a yard pass from the wife to see if ac...

Re: PS90 SBR reloads with Longshot 40gr VMax

In my case, my PS90 is the barrel length of the original 10" design. However,the heavier weight would help with the added suppressor. I'm starting to second guess suppressing this gun now with my latest end cap strike, so it may be an issue I may no longer have to worry about in my case.

Re: PS90 SBR reloads with Longshot 40gr VMax

Jay, thanks for confirming my suspicions on the ring on the factory brass. The thread you referenced is the exact information I used to make my assumption. When you were referring to me being close to neck separation, you were only referring to the factory brass with the ring/excessive shoulder move...

Re: PS90 SBR reloads with Longshot 40gr VMax

BTW, it would be awesome if one of the admins could set up a permanent sticky for all the loading information that has been provided so far, or provide a designated section for load info to the inserted for future post. A great example of this is the 300BLKtalk forum, where I have posted data and us...

PS90 SBR reloads with Longshot 40gr VMax

I figured I would share my testing results, since there is a lack of load data for this round.

Re: Suppressor POI Shift PS90 SBR

The 1/2"-28 adapter came from TROS, from when hey chopped/threaded the factory barrel. Concentricity looks good when eyeballing the bore. I will have to look into the Silencerco warranty. If it still functions fine with no POI Issue on on ther gun, it may not be work the hassle of shipping the suppr...

Suppressor POI Shift PS90 SBR

I did some testing on the POI shift due to a suppressor mounted on my PS90 SBR 10.3”. On a previous trip to a public range, I zeroed my PS90 without a suppressor out to 50yds. When I attached my Specwar762 (with trifecta mount) to my PS90, it wouldn’t even hit paper. This past weekend I went to my p...

Re: Target shooting in your home

I've found that a great method for practicing at home, to reducing the number of trips to the gun range. I use a .22LR pistol loaded with Aquila Colibri ammo and shoot at my 'Champion Rimfire Bullet Trap' in the backyard. I'm using the Aquila Colibri ammo until I finally get my silencer cleared by t...

Re: Suppressing a PS90 without SBR

I know this post is old, so sorry to bring it back to life but I didn't ever see anyone really propose a good solution to your problem. If an SBR is not legal in your state, and you want to suppress a PS90, take a look at the following link: http://www.hi-desertdog.com/index.php?_a=viewProd&productI...
