My one ounce MEC bar fits my versalites exactly to level at the top of the petal. My custom 1-1/16 oz load of lead fits to the same place or a skosh higher. My 1-1/8 bar is just at rounded full. The crimp on my STS 1 ounce seems good enough to leave alone. using a 30 bushing of Clays. Around 17 Grs. AA primer. Shot alot of them and the gun is still intact.
