XD 9mm ammo spec

[davefg34]

New to the forum and pistols. I use a XD 9mm. Shot a few rounds of Remmington 118gr. and I think it was 148gr box purchased from the local shooting range. Had one of the 188gr. jam the gun. Wondering now if higher gr. ammo is necessary or if the this was a fluke. Also wondering if there is an offical ammo spec listed some place? The forum has an entry regarding NOT to use a certain brand. Any URLs for XD 9mm specs?

Huh? 9mm? Typically 115gr, 124gr and 147gr are your options. All will work fine in your XD. Where did you buy this ammo you are noting and who sold it to you?

Yep, do bit of study. 9mm ammo is as OS notes w/ a few rare exceptions. FWIW, I NEVER shoot range ammo or unknown reloads, NEVER. Most of it is assembled in some guys garage w/ dubious components & knowledge. 9mm is cheap @ Wally, go there.

Thanks for the info. Like I mentiioned I'm new to the forum and pistols, recollection of the ammo specs is loose. My understanding is alittle better thanks to you and other experienced shooters.
My thought, for example, was the gr. index was the amount of powder in the round. Now I realize it is a designation of the projectile weight.
So is there a source for this stuff? Not really seeing any ammo specs in the XD manual.

I recommend also just buying good commercial ammo from a known supplier. You don't want to do too much digging... you could spend lifetimes learning about ammo and still not know it all. It is an incredibly deep and technical topic but there is an equal amount of bad info out there. For some basics try visiting some of the manufactures web sites and searching for ballistic test results etc. just realize there are lots of marketing gimmics out there. The forums have good info on what ammo people choose and why.

For my 9mm Winchester White Box target is my choice for ball ammo (full metal jacket with round nose)
And Winchester T series is my choice for 9mm self defense (Jacketed hollow point bullet that expands and penetrates) because it is cheap when you can find it, used by some LE agencies, has a long history, and I can afford to practice with it once in a while.

As long as you use something decent the XD will run great. As suggested unknown re-loads should be avoided for your safety, there are a million ways to screw up a re-load so why go that rout to save pennies.

Most ammo manuf have specs on their ammo on line. Bullet wt in grains (1#=7000gr) & vel in feet per sec along w/ comparative energy numbers. What does it all mean, not much. Lighter bullet have higher vel, & often penetrate less in anything they hit. Heavier bullets go slower, & higher momentum & longer shape allows for more penetration. Think ping-pong ball vs golf ball; both about the same size, one lighter, which one travels further & hit's harder? A bit simplistic, but easy enough to understand for noobs.
