My barrel is a McGowen .510 caliber 1 in 10" twist, 24" long. I think my problems if not completely resolved will be very soon. Of course I bought RCBS 500 Jeffery CIP dies, folks told me those dies combined with the new Jamison brass and a CZ 550 are a winning combination. We'll know soon. I was very encouraged that it feeds with the Barnes solids though, the Woodleighs should feed easier. Hopefully I'll be on the range soon working up a nice load with the 535g Woodleigh softpoints I have lying on my bench ....
