I'm not quite convinced about the dual diameter bullets yet for match shooting. I have a couple moulds and a swage die for the dual diameter plus the bullets you gave me to try and at this point I have not been able to get them to shoot as well as the straight shanked bullets with the long elliptical ogives.
This morning I put the scope on my new CPA and I took the loads I had loaded for Lodi to get sight settings and empty out the cases. I shot up 80 rounds of the .44-75 Ballard rounds and I must say they shot even better then when I used the tang sights

. I had enough of the old OE powder (37 rounds) I figured I could use for one day's shooting at Lodi using the 507 gr KAL patched elliptical before going to an untested load of KIK. When I finally found the paper with the KIK loads I switched to the old lot of OE the 37 rounds where loaded with and shot ten rounds and they all cut in a 2" orange sticker I used for the target at 200. That calmed my concerns that the rifle accuracy died.

The rest of the loads I had loaded with the left over KIK did pretty good also. They stayed under 2 MOA and they would have stayed on the 1K paper if the wind calls were good.
Don try that Stevens action shooting dirty. Before I put the rifle away I took the PP rounds that where patched a thousand over bore diameter and just loaded and shot to see just how many I could chamber. I shot 13 rounds with out any fouling control and never had a problem closing the breach and they stayed under 5-1/2" @ 200. only the last 4 shots fired expanded the group to 5 1/2"
