I picked up a fast twist 45 a while back. I haven't had much time to mess with it but finally got some rings and put a Nikon Omega on top. I borrowed the bolt out of a Disc Elite and had to add 4 shims to seal it up with the Lehigh plug. Anyway, I was ready to hit the range.
I was shooting T7, using a felt wad and tried both the 350 and 465 versions of Ed's castings. I've found these to shoot excellent out of my 1/30 twist Knights.
I'm not sure what I'm doing with the 1/20 but the results were OK. The early Knight build is a beautiful gun. The stock fit is perfect. It's just a nice weapon. I'll keep trying and I'm open to any good loads for the 1/20. The below results were after a few rounds to find the bull. It was a little windy so I did'nt want to stretch it out too far.
