A: Thanks for reaching out Chris! SinterFire's frangible bullets are 100 percent designed for steel targets, and they do treat a suppressor gently as well! A lead-free bullet does a great job keeping a can's baffles clean. I'd just advise checking your suppressor's manual before running frangible bullets through it – some manufacturers advise against it, and I'd always defer to them.

A: I'm sorry to hear that! I've just emailed your question directly to SinterFire's load specialist. I'll relay his answer to you as soon as I hear back from him.

A: Hi Clinton! I wouldn't guarantee that there's never at least a slight chance of malfunction. That said, I believe SinterFire's frangible bullets are the best and the law enforcement industry standard. I personally have not had a SinterFire bullet break to cause an FTF in my AR-15. I only once experienced that with another manufacturer's frangible ammo (which we don't offer on this site). I expect you shouldn't have any problems with this ammo in your M4 carbine.

A: Hi Nick! A frangible bullet is designed to disintegrate when it collides with a surface harder than itself, such as steel. Even if it fragments apart inside of soft tissue, it won't necessarily penetrate to the depth or expand to the width that are optimal for hunting deer. But a bullet like this would decimate a varmint, and probably put down a coyote real quick too. I generally only recommend frangible ammo for target shooting, or home defense when you're really concerned about penetrating walls and jeopardizing neighbors.

A: Absolutely sir, this round's brass case is completely normal. It's Boxer primed, so nothing funny going on with its flash hole.

A: Great question! I'll preface by saying this round's bullet is still capable of penetrating multiple walls, so it's not a failsafe approach to safer home defense. That said, it is indeed significantly *less likely* to penetrate its target as well as walls. Frangible bullets would be employed for very specific tactical situations because they are less prone to overpenetration and wall penetration (for example, if terrorists ever hijacked a nuclear power plant). If you use this ammo for home defense, it will reduce the chance that your shots will put innocent bystanders in harm's way as they pierce several sheets of drywall. But again, it's not guaranteed.

A: Hello Paul! I advise against firing 5.56 in a weapon chambered for 223. 5.56 is loaded to a higher pressure than 223, and may not be good for the rifle. THAT SAID, our own article on the subject pretty much says it's by no means the end of the world to fire 5.56 in a rifle chambered for 223 (luckygunner.com/labs/5-56-vs-223), and your Mini-14 shouldn't be any worse for it.
So my official answer is to avoid 5.56 if your Mini-14 is only chambered for 223, but I wouldn't be too worried about it to do it myself.
