jarhead1104 Posted November 13, 2020 Share Posted November 13, 2020 I'm shooting carry optics and sometimes PCC. Looking for load recommendations on 9mm 124 FMJ grain (i.e. primer, powder/powder charge, bullet and OAL). Thank you for your help. Link to comment Share on other sites More sharing options...
ltdmstr Posted November 13, 2020 Share Posted November 13, 2020 4.0g N320 @ 1.142 is a good place to start. Link to comment Share on other sites More sharing options...

AHI Posted November 13, 2020 Share Posted November 13, 2020 The pcc will be the limiting factor in length. A plunk test will need to be performed. So if it will fit in the PCC it should work in the pistol. With that said. 4.0g Sport Pistol @ 1.125 3.8g Bulls eye @ 1.125 Two loads that I have used that make power factor works in a pistol and PCC.

It'll be a touch faster in a PCC, but not too much. N320 burns fast enough that the extra PCC barrel length doesn't produce a lot of extra velocity like slower powders do.

oddjob Posted November 14, 2020 Share Posted November 14, 2020 After the "plunk test" I load 4.3 of Vectan 9.5 @ 1.130. Gives me about a 131 PF in my main gun and a 136 in my backup gun. Link to comment Share on other sites More sharing options...
Cuz Posted November 14, 2020 Share Posted November 14, 2020 Lets see, 9mm, here's what I have: 124gr Berry's, Montana Gold, or Zero FMJ/RN, 4.00gr TiteGroup, OAL 1.139 gives approx 132 PF in my Glock 34. 124gr Berry's RN, 3.8gr TiteGroup, OAL 1.122 gives approx 130 PF in my G34. 125gr Precision RN, 3.50gr TiteGroup, OAL 1.05x gives approx 132 PF in my G34.

Ner Posted November 18, 2020 Share Posted November 18, 2020 Can any one help me with a stupid question..? So, the question is We have a factory 9mm 115 fmj round ..with an average fps of 1150 shoted from a 4" barrel What would be the approximate FPS data of this round if i will shoot it from a 12'5" pcc barrel ? thx in advance Link to comment Share on other sites More sharing options...

Not all 12.5” PCC barrels are created equal. Your getting a 132 PF in the 4” barrel, so I’m going to guess you would be getting 1200-1250 FPS in the longer barrel. There are some variables, like powder burn rate, that affect this. you really need to invest in a chrono to confirm your results. $100 is a small price to pay for such a valuable tool.

I know i know ..but coz of a reasons it can't be done So here i am. Take for example N320, it's medium burn, right? So, +12 FPS per barrel inch ? or ?

I dropped to 3.7 with coated. Both loads run fine in my X5 Legion and Sig MPX. I've shot about 2K of this load so far. There is also some good load data in this topic: Link to comment Share on other sites More sharing options...
Jim Watson Posted December 1, 2020 Share Posted December 1, 2020 My first question is, in the present market, do you have or can you get primers and a reasonably suitable powder at all? Link to comment Share on other sites More sharing options...
Truckin_Thumper Posted December 1, 2020 Share Posted December 1, 2020 kind of a loaded (no pun intended) question. 124 gr bullet in CO should be a close to 125 as possible, in my opinion Which means it should be about 1025 FPS OAL and powder type is a big variable. In my CZs, I run them at 1.11 OAL and about 4.0 gr of Titegroup. I like the 147gr bullets better as they require less powder (3.1) same OAL.

So 132 or so, or 1065ish fps Link to comment Share on other sites More sharing options...

Some of us have been through this before and planned accordingly. Also, I've had no problems getting case quantities of N320 and 20k+ bullet orders recently. Only problem is primers.

One of the guys at my club does the same with Limited major. He plans for exactly 165 PF in a 6" gun. At one LIII match he crono'd 164 and got dropped to minor. You could have heard his howls two States over. It's just silly. My 9mm major load has never gone below 167 for the slowest bullet in any chrono string. Typically the slowest is 168. My Limited major load was 172 and never went below 170 for the slowest bullet of any string. I just don't see the logic of rolling the dice.

a matt Posted December 2, 2020 Share Posted December 2, 2020 (edited) Open major to me, there is really no reason to go under 175 and never under 170 PF. PractiScore shows PF of each shooter from Nats, if anyone is interested, Looked like some SV open s hooters ran 180+ PF along with the open shooters from the PT team. Some or often open guns like the higher PF, it seems to clam the dots down especially with the 124’s.. Edited December 2, 2020 by a matt Link to comment Share on other sites More sharing options...
bigdawgbeav Posted January 6, 2021 Share Posted January 6, 2021 According to my charts: (all out of a Canik TP9SFx) 124gr. coated + 3.4gr Clays (Canada) + 1.130 oal = 128.2 avg. 125gr. coated + 3.4gr Clays (Canada) + 1.125 oal = 127.5 avg. 125gr. coated + 3.9gr Win 244 + 1.125 oal = 134.4 avg. 125gr. coated + 3.3gr Sport Pistol + 1.125 oal = 117.8 avg. (yes I know, but I shoot Steel Challenge and PF doesn't matter) Link to comment Share on other sites More sharing options...

You tune your entire system for minimal dot movement and good tracking. You are juggling the weights. of your recoil spring and mainspring, the shape of your FPS and your load. When everything comes together you keep it that way. Right not that is 169 PF with 115s for me. The sweet spot for my previous Open gun was 172. If you shoot 124s you will need to go up in PF for no other reason than you need gas. The more comp ports and poppels in the barrel, the more gas you need to make. You can get away with that in 38SC. It is much harder to do in 9mm major. I've tried 115s, 124, and 147s. What works the best for me is all the slow powder I can put in the case under a 115 JHP.
