I've now decided that I am going to pursue the 7.62x51 caliber. For now, because I am unfamiliar with the platform, i'm going to do an "out of the box option." Given it's going to be shot at the rang, i'm sure nothing over 750 yds, what would you recommend? Yes, I'm looking for good, reliable brand names.
This is exactly what Fikays is talking about. You are all over the place, but talking like you're not. It's the exact same thing that prompted my first post in this thread; everything you're asking doesn't add up to what it is you say you want, and then you even say you don't even know what you want, but you want specifics about it. About what? Everything? You want a weapon for home defense, close quarters, shooting at the range, and now long range; you want it ALL in one gun. However, the bulk of the intent is for home defense, close quarters and short range shooting, correct? Yet, you've convinced yourself the 7.62 is what you're going to do, although admittedly are unfamiliar with the platform. So, you're going to throw down on something you know nothing of for the weapon you want to have to do it all? And based off of what?.....the extremely little amount of info you've gotten here? Some of this info may even be the bogus ramblings of internet experts.......how would you know?
To the real point (at least according to you), what in the hell are you going to use a 7.62 for home defense for? Are you defending the home itself, or yourself while inside the home? I would love to see your neighbors' faces when you boast to them that you are getting a howitzer for "home defense". The thing you need to do is get serious with yourself about what you really want, and what the correct weapons are for each need, instead of wandering all over the map looking for single, anecdotal pieces of info to build your case to yourself to find the miracle gun that will do it all.
I think you've got other factors influencing what you buy that you haven't mentioned and are in here just "talking gun" bs to kill time while you're at the airport/hotel, almost like you're trying to justify a toy and need plausible ammo for that.
