Have you looked at the Remington M700 Police? While I do not like the extractor on the M700, the qualities incorporated into this particular model off-set any concerns I have.
Specifically, I most appreciate that the Police model is parkerized over 100% of its steel exterior surfaces and interior surfaces, including the barrel's chamber and bore. These rifles average 0.50" at 100 yards from the factory. There is a company that reworks these rifles for LEO and military service, recutting the chamber and guarantee then 0.25" accuracy at 100 yards.
At an approximate $1,200.00 for this rifle, you will be hard-pressed to find a better rifle for your stated purposes. And don't bother scrubbing the bore to try to achieve that silver shine...the bore is charcoal color when clean, due to being parkerized. Very good quality rifle...I had one in .308 Win, and accuracy was fantastic. They were manufactured in .223 Rem, .308 Win, .300 Win Mag and I read somewhere that Remington had added the .338 Lapua.
Good luck, and let us know what you purchase.
