16" Barreled PCC, Colt Pattern, 9x19 Chrono data ... 129rds chrono'd


bfoosh006

Recommended Posts

129rds tested so far...



As always... YMMV... so please view my carbines data as just my results... the same barrel, under the same conditions, so as to eliminate variables, .... your carbine might be faster or slower slightly.

I want to make sure everyone realizes my results are from a Colt Pattern Carbine, with a mag block insert..... any feeding issues might not happen in a Glock Pattern, or a designed from the ground up 9x19 carbine ( Beretta, Sig .. etc.. ) So take the feeding issues with a grain of salt.



I realize most people are not really concerned with the velocity of various 9x19 rounds... but ...My goal was to see what will run in my carbine, what the velocities were , and "guesstimating" what the added velocity would do to the various JHP, Bonded HP's, Copper HP's etc.... ( You have to start somewhere... )

A good example would be the Fed. XM9001.... that older design bullet already penetrates to a shallow depth.. and the added velocity will probably make its penetration depth less... kinda acting like a "varmint" 9mm round.

I also know there are various other sites with very helpful info ( BBTI ) ... but, some of their data is kind of dated, and does not include the newest rounds.


Weather.....68 degrees, slightly overcast, chronograph was 12 feet from the muzzle.

18rds of each 9x19 ammo was chronographed...
The reason being, I am going to later conduct a 32rd mag test concerning reliability / feeding and accuracy test... I will include the FTF and FTE , etc from this round of testing.

My "standard" for velocity checks, is GECO Swiss 124gr... I have found it to be very consistent and accurate... so I used it every hour to spot check velocity.
Just to make sure the sun or "murphy's law " wasn't skewing chronograph results.

Rifle info....
PSA 16" 9MM Colt Pattern Hybrid, 1n10 twist, Lantac Muzzle Brake, ALG ACT trigger with JP Springs, 6.75oz Buffer, Tubbs .308 variable power spring.

Competition Electronics ProChrono Pal Chronograph was used....


General observations...

Not all 9mm is created equal... I observed numerous nasty bullet setbacks.. Photos will follow later... but it was obvious some brands use better QC and neck tensions / crimp pressure.... ( Remember YMMV )

Only one 9mm OEM round would not cycle consistently, it should be noted that every other FMJ bullet fed perfectly in my carbine, but not the MaxxTech 115gr FMJ ... and it was VERY low velocity as well ( compared to same weight ammo ) perhaps the low velocity contributed to the feed issues.....

While some of the ammo was expensive, those same rounds were very impressive in function.. I have to say Buffalo Bore ammo was 100% reliable....even while using the same bullet ( Barnes X bullet ) that other manufacturers rounds had trouble with.

I expected some JHP's to choke while feeding, simply because of the HP's profile and the less then perfect feed ramps of a Colt pattern carbine.... and some did.... consistently across the weights.
That is NOT to say it is bad ammo... just not a good choice in my AR15 Colt pattern 9MM... that same ammo might feed perfectly in a Sig MPX... Or a Glock Pattern AR....or such.

As we all know... a blowback 9mm carbine can get filthy quickly, and some ammo burns very clean... while some burns filthy.
If you are running a suppressor..... I strongly suggest you use the cleanest burning, fully coated / "sealed" bullet.... I was just starting to have issues with chambering at the end of the day.. from the gunk that had accumulated. There was no noticeable effect on velocities... just function got sluggish.

Interesting, but not surprised.  I've done stuff with my AR45 that blows my mind.  Center-mass hits at 200 yards on steel, point-of-aim, with a damn .45ACP round.  All because of the 16" barrel. That would never happen from a pistol with a 5" barrel.  :thumbup:

 I know nothing about the 9mm AR , but is there a reason a 308 Buffer spring is being used ?

"Bark and Blast" can be quite a bit in a Blowback 9MM... so the heavier spring helps "delay" the BCG cyclic action by milliseconds... and that cuts down on the "BaB" quite a bit. As well as keeping the action cleaner.

The OEM buffer spring and buffer was cycling very fast, enough that it felt like it was gonna pound the buffer tube "apart"..changing over to the .308 Tubbs spring and a 7.5oz buffer makes the carbine much "softer" shooting.

To heavy of a buffer and spring combo will result in "muzzle dip" and possible bolt bounce ( the heavy recoiling buffer and BCG will bounce off the receiver face, just like a steel hammer off an anvil ) ... so for most all Colt pattern and AR based 9x19's ( Glock pattern ) you will need to finesse the spring rates and buffer weight. The 9MM AR was an "after thought" adaptation design as opposed to a ground up build like a SIG or Beretta 9MM.

Everyone that has fired my Colt Pattern 9MM loves it, it took quite a few spring and buffer weight combos to get to a pleasant shooting carbine.

I will add... 125yd shots are VERY easy to shoot accurately with even just a 3 MOA Red Dot.... it is much quieter then a 5.56 16" and is very lite recoiling. And I can use it at the local "Action Range" so it makes for great manual of arms training.

All and all.. it is a very fun carbine to shoot.

  Interesting you can use a 308 AR spring , If its a Tubb's Flat wire Spring , you cant go wrong by using one or any of his products for that matter .. Tuning the AR with different weight Buffer Springs & Buffers are the way I use to tune them , I have no Arg. Gas Blocks , except for the one that came with the Superlative Arms Piston system , it came with it .

On a side note... when I talked about trying so many different buffer weights and spring weights, I went as high as a 10.0oz solid buffer and a Orange .308 Springco 24.8lb ( opened/locked back ) ... the irony was all that heavy mass and heavy spring power did was move the nasty recoil to the front of the carbines breach ! Lol !! ( strong muzzle dip )

Just goes to show how tolerant the AR 9MM is !!

In case some of you guys aren't aware of various spring weights... David Tubbs has that info for us.


A2 (old) - 7.6lb closed, 14.5lb open
A2 (new) - 9.1lb closed, 16.7lb open
Tubb Flatwire - 10.5lb closed, 16.3lb open
Tubb .308 Flatwire - 13lb closed, 16.7lb open
SpringCo White ? (standard) - 8.3lb closed, 16.3lb open
SpringCo Red (extra) - 10.5lb closed, 18.4lb open
SpringCo Orange (increased) - 13.9lb closed, 24.8lb open 

The video is worth watching.
