Not sure why you keep bringing up Mosin's in your arguments against your high end rifles, they are garbage rod rifles & not worth even bothering to try and make accurate. This whole debate was because you think Rem's are inferior. I don't even like Remington but there are good 700's out there that do the job just fine.
The only reason I can see a high end rig like the ones you're talking about are dedicated rifles that are shooting well over 1,000+ yards. Remington 700's & Savage 110's are shooting just fine at 1,000 yards.
The question is, why would anyone need a 1,500 yard gun to target intruders at shorter ranges? The whole conversation started with a 600 yard distance. In reality, a person looking through a scope isn't going to be able really tell who's friendly and who's a potential foe. Just as easily targeting some person foraging or a group looking for family or friends. I stand by my statement that targeting civilians at long distance's, it's irresponsible and criminal. We're still all American's even in hard times, you don't need a 1,500 yard rifle to defend yourself from hungry people. You couldn't even tell at that range who anyone is, could well as kill your own mother thinking you're defending your home from thieves.
A more reasonable is a range of 200, maybe 300 with a sign posted regarding the process for communication. Targeting people because a person perceived them as a threat isn't justifiable.
Even 600 yards it's less to do with top tier rifles and more to do with an accurate rifle with good ammunition and clear glass. Just because you want to spend $3k+ on what a $800-$1,000 rig can do is purely on want's, not need's. Just because your ego is stroked from owning what the specialists use doesn't make you anymore of shooter than someone that chose a Remington 700. I chose a Savage 10FCP HS, & for shooting up to 1,000 I wouldn't need anything else.
