on any bolt type rifle I use the same as Rodsmith; I take the bolt out and set the gun in a gun vise and look down the barrell to get it close,then adjust the scope to that and go to the range.most of the time you can get it to within 5 or 6" to start with.

the rest is fun !!!!

remember keep your back to the sun, your knife sharp, and your powder dry.
