It might be great, but I can't say much for their marketing skills. Neither the description nor the photo gives pertinent information on how it attaches to the loading arm. I don't believe I would buy one without knowing how it worked.
For my shorter Barrels, I use one of these screw drivers with the tip a reversible tip. The handle is red,and you usually find them on the counter at hardware stores for like $4.00. Perfect for what you want. Happy hunting.
i have a remington pietta 44 sheriff [5 1/2"] which i have loaded .457 balls in with no problem. sounds like i should be ok with a short 60 barrel, especially since i now have a .450 mold.
