Hey guys, First, I'm an absolutely new to this whole world. I've never owned a firearm in my life. I just bought a Glock 19 with the main purpose of home defense, but also to enjoy recreational shooting at the range. That being said, I wanted to educate myself a little on different aspects of firearms. First, I wanted to start with ammo. I've been researching, and reading different articles. I'm starting to understand a few differences between different ammos, but I have some questions still that I can't seem to find straight answers to. First, I'm wanting to buy two sets of ammo: one for self defense, and the other for shooting at the range for fun. As far as the self defense ammo, I think I've narrowed it down to three different types. I wanted to get y'all's opinion, and see if there are any other SD ammos I should consider. 1. Remington Golden Saber 2. Winchester SXZ Personal Protection 3. Federal Premium Guard Dog As far as range shooting, I've just been using Remington Luger 115 grain. At some point, I will use all four of those at the range. I would like to test the three home defense ammos to see what feels/works best for me. But my local range has this posted on their website: "We only ask that you not bring steel or aluminum cased ammunition, or steel core, steel jacketed, copper coated steel jacketed or armor piercing projectiles." Do any of the above ammos fall into one of these categories? I'm not exactly sure what ammo falls in this category to be honest. Anyways, thanks for helping out the new guy!
