Mulligan03 Posted January 19, 2017 Share Posted January 19, 2017 Mine won't cycle 147 factory ammo all the time.. what have y'all found that works in yours? Won't to try some different loads for mine when it gets back from sig..(something wrong with gas system, wouldn't cycle anything).. have a jp on the way if they don't get it straightened out Link to comment
Posvar Posted January 19, 2017 Share Posted January 19, 2017 My gen2 pistol will now run 147g Xtreme on 3.4gr of Tite Group. It needed break in with about 700 rounds of factory ammo and then a really good cleaning. My gen2 carbine won't run 100% yet with that load but it's getting better. Main issue of FTE. I'm trying 124g next at 4.1gr of TG. Link to comment
Mulligan03 Posted January 19, 2017 Author Share Posted January 19, 2017 Mine wouldn't eject either and the bullet loading from mag kept getting caught up with spent casing.. and that was with 115 hotter loads Link to comment
tyler2you Posted January 19, 2017 Share Posted January 19, 2017 My gen 2 runs 147 BBIs with 3.4 grs of Titegroup as well as 3.7 grs of HP-38/W231 at 1.125 OAL with zero issues. It required about 200 rounds to break in before it was reliable with these loads. Link to comment
Mulligan03 Posted January 19, 2017 Author Share Posted January 19, 2017 Ok thanks.. hopefully when I gets back from sig it will run perfect.. it has always run hotter loads fine.. don't know what has happened that caused it to start having issues.. didn't Change ammo or mags or anything Link to comment
Neomet Posted January 19, 2017 Share Posted January 19, 2017 (edited) Did you send it to Sig to open the gas port? As I hear it they will open it from the .045 to .050 that was the dimension in the Gen 1s. To answer your question though I am running 3.5 of E3 under a 125 moly at 1.135. It is higher than 130 PF but still stupid soft. Edited January 19, 2017 by Neomet Link to comment
Posvar Posted January 19, 2017 Share Posted January 19, 2017 Does Sig open up the port free of charge? If so I will send both of my barrels in. Maybe after that I'll trust them 100%. Link to comment
Mulligan03 Posted January 19, 2017 Author Share Posted January 19, 2017 I just called and ask guy at sig if opening up gas port was an option and he said it was at discretion of who ever looks at my gun.. I told him that I wanted it to shoot light loads Link to comment
Posvar Posted January 19, 2017 Share Posted January 19, 2017 Ok so you have to send in the whole gun. Let me know how it ends up. Matt Link to comment
2011BLDR Posted January 19, 2017 Share Posted January 19, 2017 (edited) I found that in my 16" gun my 125gr Montana Gould JHP @ 1290fps (5.6gr N340) was softer than the same bullet @ 1160 fps (5.4gr 3N37). I am convinced you can short cycle this system and induce more recoil and counter recoil bounce, while still ejecting and feeding. The 3N37 load was initially 1090 fps and not reliable brass fell out the ejection port at your feet. I reduced the OAL an gave it a bit more crimp to get it to 1160fps. Any NATO/ European spec 124gr 9X19 ammo is going to be 1280-1325fps. The ability to simply buy good factory ammo for a flyaway major match instead of having to bring hand loads on an airline is one of the reasons I like PCC. Another reason is if Iam low on brass I simply buy a case of good NATO/ European spec 124gr 9X19 ammo that matches my reloads. Edited January 19, 2017 by 2011BLDR Link to comment
Neomet Posted January 20, 2017 Share Posted January 20, 2017 Kevin, I do think you are onto something. I haven't quit playing with higher PF loads just yet but at this point I tend to agree. I was at 2.7-2.8 E3 for 130pf and am running 3.6 now. The dot seems to have less bounce and I honestly don't notice much difference in recoil. I have no idea why and want to compare again to be sure but if this works I can have one load for my MPX, my 3 gun Tac Sport and my Production Shadow. Win!! Link to comment
Posvar Posted January 20, 2017 Share Posted January 20, 2017 Update....my carbine is running my 147gr Xtreme @ 3.1gr Tite Group like a champ! I broke it down completely and cleaned and oiled it and it is running like a sewing machine. Link to comment
Neomet Posted January 21, 2017 Share Posted January 21, 2017 Posvar, what PF does that come out to? Link to comment
Posvar Posted January 21, 2017 Share Posted January 21, 2017 I will chrono it next week as I have an all day match today and will not be able to do it tomorrow. Link to comment
Aircooled6racer Posted October 9, 2017 Share Posted October 9, 2017 Hello: The softest one I have tried so far in a 8" MPX is 122 grain Acme, 3.1 grain Tite Group, CCI primers and 1.140" OAL. It chronoed 116.9-124.1PF. It ran 100% but the bullet was slightly touching the lands. Thanks, Eric Link to comment
Ming the Merciless Posted October 10, 2017 Share Posted October 10, 2017 My Steel Challenge load is a Montana Gold 95gr JHP bullet over 4.8grs of N330 at 1.15OAL for 1,000fps (95pf) out of my gen 2 MPX carbine with the factory barrel. It ejects about 10 feet to the right front at about a 45 degree angle. Link to comment
RH45 Posted October 12, 2017 Share Posted October 12, 2017 IN my Aero survival rifle, 3.9 grains of VV320, behind a 115 grain fmj, gets me about 137pf. Gun has a comp, and recoil reducers in the stock. In my MPX, which really only has about a 14" barrel, with the comp, welded on from the factory, the mentioned load only generates 120pf. I'm now running Extreme 115 hp bullets, with 4.2 grains of VV 320 behind them, to get 135pf. I'd also tried some loads with Autocomp, and VV350, to see if they would work the comps at all, but, went back to VV320. I tried heavy bullets in both carbines, and didn't like them at all.

Aircooled6racer Posted October 12, 2017 Share Posted October 12, 2017 Hello: I am using Acme 115's, 3.8 grains of Tite Group, Winchester small pistol primers, 1.125"OAL. It gives me 133-137PF out of a 8" barrel. I am really liking this load for USPSA pistol matches. I will try some 124's next. I don't like the 147's but they are very accurate at 50 yards that I tested them at. I still have not tested the 115's out to 100 yards yet. When I tested bullets before the 124's did better at 100 yards. Thanks, Eric Link to comment

That said, even with the big dot, my load, with Extreme 115 grain h.p. bullets group under an inch at 50 yards, which is as far as I will ever shoot at a USPSA, or IDPA match. If I ever decided to do a regular PCC match, or a 3-gun match, where I would expect the targets to be further than 50 yards, I’d put a scope on. Link to comment
Aircooled6racer Posted January 23, 2018 Share Posted January 23, 2018 Hello: Anyone have a good steel challenge load for their MPX? Going to try 115's with 3.6 grains of Tite Group. Thanks, Eric Link to comment

That said, with the one that works with the lightest loads, it would be right on the edge of reliability, but, shooting steel, with only 10 in the mag, you might be ok Link to comment
Aircooled6racer Posted January 23, 2018 Share Posted January 23, 2018 Hello: I tried some of my 147 grain Acme with only 2.8 grains of Tite Group and they cycled my MPX 16" just fine. They felt really slow and only ejected about 5 feet away. Mine still only has the stock Gen 2 gas port. Thanks, Eric Link to comment

I'm trying 124g next at 4.1gr of TG. Same load I was using. It was 100% for me but that was after 2k+ rounds. I actually found out by mistake. From all the different bullets and powder, I found out that heavier and slow was always the best for the MPX. I found 124gr (I used CFE-P/ WAC) gave me the best muzzle management.

TRUBL Posted January 24, 2018 Share Posted January 24, 2018 been running Remington UMC 115gr out of an 8" factory barrel with no issues........hands down one of the lightest 115gr loads I've shot, actually considering to run this over the 124 PMC next season. Link to comment
