  1. I’ve been playing with mine on the timer and my fastest splits with close hits on the target is with 4 steel and 1 tungsten. I would try 5 steel if I had a fifth one. This is with 130pf 124gr JHP using N320. 

     

    I believe the short stroke kit I purchased to go from 4 to 5 mass was a 3 tungsten and 2 steel combination. I think it was softer shooting with that setup but not as fast grouping my double taps. In a match I haven’t noticed the gun recoiling any harder. 

     

    I will probably play around more with it later but as of right now I’m happy with the setup.

  3. JP GMR-15 is a great pistol caliber carbine! Used it tonight in its first USPSA PCC match. The carbine ran flawlessly, me not so much. Have about 1200 rounds through mine now without the first hiccup. And yes I did the barrel breakin just because. 

     

    Looking forward to shooting a Steel Challenge Match this Sunday with mine.

     

    Good luck with yours.

  4. The RO I just got doesn't have the ILS. I read somewhere those are the California legal models that have them now. Mine has not missed a stroke in the first 500 rounds. All I did was lighter the trigger a little.

  5. I use to throw all the SPP 45 brass away but there is getting to be so much of it now I have started saving it for lost brass matches. When I go to load them I will have to see what kind of speeds I get across the chronograph with both SPP and SRP before I kick up the charge.

  6. In about 7 months I'll let you know. I have an Infinity open gun on order so we shall see how it compares to the custom built open gun I'm using now. I sure hope it's all that people say it is because it is considerably more.

  7. So you are 8 months in, have you started your next gunbuilder project yet? Oh, c'mon...be like the rest of us and always have another one ready to go........My problem is that Brandon keeps showing me new things and finishes. Have you seen the new nickel finish he is doing with pocketed diamonds? It's just wrong that he keeps coming up with options such as that.

    Wishing you have an easier next few months of waiting.........or you could come down to the Infinity Open in June and see the progress of your pistol in person. Just a thought.....and drop off your deposit for the next coolest thing you ever saw like I always end up doing. One of these days, I will learn. One of these days.....

    Not yet but been thinking about one. I will probably wait until I get this one since it will be my first Infinity, then maybe a single stack 1911 just because I don't have one.

  8. I've ran a 550 since the 80's, purchased 650 a few years ago with case & bullet feeder couldn't be happier.

    I still have the 550 and run smaller batches of ammo on it, mostly revolver & rifle since I don't shoot much of that but the high volume stuff goes on the 650. The 650 isn't difficult or take up too much time to swop between primer size or calibers if you have tool heads setup with your dies.
