I plan on having some pictures after Easter.

Another up date on the bore diameter situation. It kept sticking in the back of my mind why would the barrels be marked 40 gauge if they were .510". I can't imagine H&H making some kind of mistake like that. So I switched my measuring tool, and shoved soft lead plugs all the way thru both barrels....after very careful measurement both bore come out as .505"!
So obviously no more .510" Woodleighs will go down my barrels. Apparently the 440gr Woodlieghs are very soft and were able to swedge themselves down to .505" without busting something, but I will not take that chance again.

Hawk bullets makes .505" SP bullets in several weights. I'll try some .505" 400gr projectiles with the 50gr 4759 powder charge and see how they do. Pressure should be less and velocity greater....we will see.
