I recently bought a hog hunter in 223 rem and the only things I did was install a one piece rail, and Weaver Kaspa 1.5X6. I then thoroughly cleaned the barrel, ran a wet patch of LockEase down the barrel. Lastly I loosened the action bolts, placed the rifle vertically to get the recoil lug against the stock and tightened the front bolt to 30"lbs and the rear bolt to 20"lbs.

Off to the range for 1st 5 rounds, clean barrel, then 5 rounds for grouping. The only problem I had was that it took me 5 rounds to zero
