OK, I'm new to "Semi Auto" reloading and I just read something about "Hammer Fallow Thru" in AR's, and it was mentioned that "Hunting" ammo had softer primers that could easily allow "Hammer Fallow Thru", as opposed to "Military". Should I be aware of some "Harder" primers out there that I am not aware of? Or can I use regular primers, same as I use for my Thompson .223 single shot.

Thanks,
Gary.
