Bolt Sleeving

Bolt sleeving is not new to the gun smithing industry. It was tried and used by other smiths before I came along. What has set me apart has been the reamer/mandrel I designed, with interchangeable bushings. This results in a bolt raceway with the same diameter bearing surfaces, along with front and rear sleeves on the bolt that do not lockup when cycling the action. As seen on the blue printing of this web site, the same tool is being used to dial in the axial alignment of the action to true center of the bolt bore.

In the picture below, is a setup from my bolt sleeving video. It shows the 0.0084 cant that is induced by the poor fit on a new Remington action. This will cant the top bolt lug 0.0019 off of the top action lug seat. This happens every time, no matter how true the action is. The only cure is bolt sleeving.

By sleeving, you produce consistent ignition of the primer and powder, stop bolt movement during the lock time and primer ignition, and eliminate a secondary vibration produced by the bolt slamming down as the powder ignites. One less vibration to deal with when tuning a load - all by bolt sleeving.

What actions need sleeving? Anything with more than 0.001 slop. I fit to 0.00025-0.0005 clearance. Whether it's new or used, production or custom, for competition or hunting, my system works!
