[QUOTE="Boss Hoss, post: 445772, member: 5060"] The way I do all of my rifles with respect to process is the same. Jamming is not smart esp on a hunting rifle but people do it and still really do not understand why they may or may not get smaller groups. Using a 700 style action---remove firing pin assy---remove extractor---(this is also how I judge sizing of brass by resistance to the bolt closing then back off .02 to .03) then mark the bullet with a black marker from the ogive back. Place round carefully and close bolt then look at the bullet. What you are looking for is the point where each land makes a complete line (not 2 lines and 1 dot and nothing for example on a 4 grove tube) that will cause the copper to show. Then back off what you feel is appropriate for the purpose of the rifle as obviously a BR rifle is going to be different than a hunting rifle. When you do this you have established the shortest distance for the bullet to travel and engage all of the lands as close to the same time as possible. This is the way my smith does it and he is a HOF shooter. Have never had anything but success doing this on around 20 or so rifles and 30 tubes when working up loads. Also when you have the firing pin assy out check the bolt shroud to ensure no contact----any contact there is bad ju ju for accuracy!! [/QUOTE]
