And, because of the low velocities, powder coated commercial bullets won't work well. Drawing your attention to PeeWee's earlier reference (several pages of posts ago) to Glenn Fryxells book, from Ingot to Target (available free here at Cast Boolits, check the Stickies Area), the low pressures don't allow the back end of the castings to obturate properly. Typically, commercial cast are much too hard an alloy for this game. We purposefully blend lead alloys to get the proper amount of lead softness for the bullet to work well in the barrels. About BHN 6 is pretty good for the game. Normal pistol bullets might be 11 or 12, or even 13. That's way too hard for this game. Take a peak at Glenn's book. Lots of great handgunner info in there.
To properly put it in some perspective, we custom cast, custom size/lube, and custom load the ammo for these highly tuned guns.
