I have only stuck a couple bullets in bores over the years. I went to XXXXX Hardware Store and spent a few bucks on brass rods close to land diameter and gave them wraps of duct tape until they were at land diameter. THEN I tapped out the bullets after LOTS of Hoppe's and a bit of RIG +P laid down in the direction of travel.heck Allen.
you know the older car-truck antannas work as 22 cleaning rods if you nipped the ball off the end.
