Change in powder charge of FMJ 9mm ammo?

[peacebutready]

Years ago I bought and shot several boxes of Brown Bear steel cased 9mm FMJ ammo. My memory is telling me it was loaded on the light side. Recently, I noticed the video below which shows Brown Bear 115 grain 9mm ammo moving at blistering 1324 fps out of a 4.95" barrel. Could Brown Bear have boosted the powder charge a few or several years ago?

I've got a few boxes of Brown Bear that no gun will reliably extract (tried it in 9...including a PC9 carbine and Spectre which have about the biggest and toughest extractors known to man) and refuse to even try it ever again. Somehow I feel they don't have perhaps the finest QC or they're sourcing ammo from many different plants and stuffing them into the BB boxes so it's a crapshoot as to what you'll get. The ammo I got was cheap enough that it was worth a try, but in the future I'll pass unless someone can affirm that they've made serious changes to how they make their ammo.

Maybe they were made years ago and are too light to extract reliably. That's my guess. If you can get a single box of BB, it may be worth a try.

I don't see anything surprising about the velocities found in the video, it is typical of full power standard pressure ammo. The original weights and measures listed in the video showed the bullet weight to be under 115gr @ 112gr so a lighter weight bullet can be driven faster from an equal pressure round. 1,324 fps isn't that unusual esp from European ammo loaded to SIP standards rather than SAAMI. Have seen equivalent velocity from Fiocchi 115gr JHP that was manufactured in Italy.

I have ran 2 different steel case Russian manufactured 115gr 9mm samples over my chrono in years past. A sample of Wolf ammo had an average velocity of 1,219 fps from a Glock 19. The other ammo was ammo manufactured at the Ulyanovsk (sp) plant and it averaged at 1,255 fps from a Taurus Pt92 with about a 1" longer barrel.
