I have a R700 LA in 7 rem mag. I removed the factory barrel and installed a .300 prc remage. If I use the stock recoil lug, I should be able to reinstall the 7 rem mag barrel and have it headspace properly. Right? And if I red loctite the barrel nut to the remage barrel the headspace should be correct if I use the same recoil lug and swap barrels. Right?
