NOTE : the rounds with the ............ lines are just ones I am waiting to be delivered, so that data will follow later.
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 almost very other FMJ bullet fed perfectly in my carbine, but not the axxTech 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.
Onward to the velocity results.... ( accuracy and 32rd reliability tests will be part 2 )
