I have the .223 Remington 700 Tactical, all I’ve done to it was add a Nikon P-223 4x12 40mm BDC 600 Scope using the M-223 mounting System, and I’ve had no problem using 55grn to 77grn, my range has a limit at 400 yards and have no problem hitting targets. I wouldn’t trade my Remington for anything.
