Bob,
I don't know what the Hornady are like for the .30-40 Krag but I found them to be short in other calibers. But this might be good for the .38-50 to keep the trimming the length down
The Winchester brass I won't complain about. It has shown very good accuracy despite the long freebore my chamber has that tends to throw a round out if I don't use a proper bullet for this chamber.
Below are some ladder loads using Swiss and Olde Eynsford.
I pulled out the chronograph to see what this .38-50 pushes these 357 gr bullets. I just shot here on my 100 yard range that has been shooting the best on the 200 yard range with a couple different types of powder and loads.
All the bullets were cast with my alloy I use that is a 1# roll of 95/5 no lead solder 95% tin/5% antimony and 18# lead except for the 5 rounds using Arnies WW/Linotype alloy. For some reason I got one round loaded in a 303 British case that got mixed in with the .30-40 Krag cases. The .303 Brit cases are .039" shorter. I would not have thought that they would slow the bullet down about 20 fps, but it did.
The orange dot is 2". I seldom use the chronograph and I was surprised that the groups held tight at 100 yards like they did with the ES spread.
I think bullet release has a lot to do with the ES. I will turn the necks as soon as I make the proper pilot for this caliber.
The left target was shot from the 200 yd line.
I'm starting to really like this little .38-50 Hep. I wish I would have had one sooner now.
