Nice innovative trick there far_shot. I usually do 1 wet and 2 dry pulls myself as well but the 3 are done individually. I toss a rod down the barrel and attach a string at breech end long enough to pull through to muzzle without pulling the patch through yet, then with the rod out and string coming through muzzle I pull my patch by hand. Much more time consuming than your method, may have to try it out!
