Hello Mas, I hope you're doing well. Per your recommendations, I bought a Mossberg 500 Bantam 20 gauge shotgun for my girlfriend. She's a smaller girl, 5'5", 120 lbs. It's her first gun, and she really likes the youth size, and is becoming quite handy with it. So far, the only buckshot I was able to find was some #3 Remington buck...20 pellets at around 1175 fps. Today, I found a couple boxes of Federal #4 buck...24 pellets at around 1100 fps. I haven't checked the patterns through her gun yet, since I just bought the 4 today. May I ask which load you'd recommend? This webpage seems to recommend the first shells to be #4, with the balance of the magazine filled with #3. http://internetarmory.com/shotgun_ammo.htm Does mixing loads make sense for a home defense role? Lastly, I looked at NML's http://www.custombuckshot.com/ Any favorites? Thanks, Brad Wanna kill these ads? We can help!
