howdy Bullaboy,
Lyman 311008, 20/1 alloy (though I'm not really very scientific about it as I scrounge lead where ever I can) they usually drop from the mold at 117 grains, I don't size, they fall just a hair over .313" and I pan lube them with "Magi-lube."
As Wind said my Cowboy Carbine likes 4.5 grains of Unique best. Besides Bullseye I haven't really tried anything else. Unique is one of those powders I started out with and then used a bunch of others with mixed results (SR 4756 being the best) but came back to Unique and found it really did everything I needed it to do in a lot more calibers. My 45 Colt, 38-55, 30-30 and this 32-20 seem especially happy.
My sight is a Marbles. It has just enough threads for a right on hold at 500 with a very short front sight blade. I'll actually have to switch out the front sight to be able to use it for Cowboy silhouette which is my primary purpose for this rifle I'm about 8" high at 50 yards with the Marbles all the way down and a foot high using the open rear sight on the lowest notch.
I'm new to the 32-20 and still on the steep part of the learning curve. My skull is pretty thick - especially at the brow - and my absorption rate is pretty flat. That makes the discovery process last longer and keeps me giggling until I stumble onto the next thing I thought I knew but didn't really until I tried whatever it was that someone wiser than me told me years ago and a new tier of understanding is opened up to me. I only wish I knew I could shoot dingers at long range with old iron sighted rifles when my eyes were thirty years younger.
