They're great self protection - Federal Premium Syntech Defense 9mm Luger 138 Grain Segmented Hollow Point Centerfire Pistol Ammunition

They are good bullets but out of the 20 that I got only 19 are good because one has a light hammer stripe and got put into my Box and sold to me with 19 good bullets and 1 dud now it could have been an accident But I hate all the middleman I'll keep planned at once to know it took longer than ever to get these Bullets and also to open the 1st Box And see the 1st bullet with the light primer strike so went to my brother and my dad and I'm the bullet said what does it look light that's 3 men born and raised with guns all looked at it set a light primer said no brand new out the Box they said no that thing's been attempted to be shot So how do I suppose to use that as self defense just put it in and hope it shoots for me but it wouldn't shoot for you
