[QUOTE="SeniorSendero, post: 45228, member: 2287"] I used lapping compound on the back side of the lugs, insert the bolt back in the rifle and worked the handle up and down til I got 80% contact. Doesn't take long and you don't want to do to much since it will increase your headspace. You normally only need to lap about .0005" to .0008" to get this so it won't get dangerous. You can check this easily by taking a marker(poor mans Dykem) to the back of the lugs and working the bolt handle up and down the same way as lapping. Now just check and see how much ink is left. Rinse the area of lapping compound well with brake cleaner and clean and swab the bore afterwards. Ronnie [/QUOTE]
