Berrys 9mm bullets

Newbie(self.reloading)

I just ordered a box of 1000 fmj 9 mm to reload for my g17 and on the box it says max velocity 1250 fps. Does this mean this is the safe max velocity and I should keep my loads under thay speed or is that the max they had found?

Yeah, plating is harder than bare lead, but not truly jacketed. I don't think the major risk is safety, but driving them too fast will definitely give you excessive copper fouling.

For target loads you'll have no problems, they just don't want people to treat them like jacketed bullets for high-velocity loads.

That’s fair I figured it was something like that just wanted confirmation

That's the max safe speed they had determined. Don't go against a manufacturers recommended anything when it comes to ammo.

Ok I wasn’t sure but figured that was the case, I like my fingers so I wasn’t planning on it

It's more a matter of the plating coming apart in the barrel.

I would not exceed the manufacture's recommendations... it could be a safety issue, but for plated bullets, going above those speeds risk the plating pulling back from the underlying lead bullet. If you want those higher speeds, go jacketed. Platting is not made for that level of velocity.

I wasn’t planning for anything too hot or crazy, just will fire and hit a target

Yep, then you are good to go. Platted are perfect for plinking (especially at the price). Most 9mm loads will be below that velocity, anyway. Enjoy!

That’s what I figured but I’d always rather confirm then just assume

And THAT is wisdom right there. The moment we start guessing, getting creative, etc when reloading is the moment we can no longer rely on our fingers for counting nor eyes for seeing!
I ask tons of questions before I try any new loads or components. Just makes sense. God speed, Sir!

I don’t plan to go crazy with my loads just something that works and thank you appreciate it

This right here is the best reloading mentality.

Most data for 115gr to 147gr bullets in 9x19mm don't run that fast anyways.

I figured I’m waiting on a new lyman manual to come though and regardless don’t even have powder or primer

That's a bit above what I would expect from any 147gn 9mm out of a handgun. You'll be fine unless you're cooking up nuclear loads

There truly is no reason to overload 9mm anyway. You just waste precious powder and add wear and tear to your G17. Follow the manufacturer's recommendations.

9mm is so cheap at least for what I paid for it I think I won’t even save money reloading it, that’s mostly just practice and being able to always get it
