For high-volume shooting, some guys take at least two rifles to a PD town.
Aside from giving the barrel some cool-down time, you might consider loading to less than maximum pressures. 3,700 ft/sec is fun, but a PD can't tell the difference if the bullet leaves the muzzle at 3,400 or so...A good 50- to 55-grain BT bullet oughta give you good results to beyond 300 yards.
