I like your thinking.
If I have a choice, I’ll start with my 7.62 x 54R at 500-600 yards. They’re gonna have to have their own good bolt rifles to touch me.
I was fortunate enough to come across a Springfield Armory M1A National Match model about 10 years ago being sold by a gentleman going through a divorce.
I paid an entire $500.00 dollars for it.

I prefer to maximize my chances, and they are gonna have to locate me first. Assault style weapons have a purpose, but if you are in range to use them effectively, the other guy is too.
