.38-50 #2

[Kurt]

Today I finished the third stage of forming these 300 cases. I fired 73 cases this morning for the final forming and I had a few that were short so I wanted to stretch them .15-20 thousands and get them trimmed for the proper length I need. I worked out by trial and error over the years how much neck tench ion and how to dampen the chamber enough to get slight stretching without over stretching the case and it works very good.
The 200 yard range was busy this morning with a 3 race gun match so I had to use the 100 yard range. Just as well for just forming brass.
I shot another shot gun pattern . Here is one target I shot at 100 yards. This really shows how important it is to properly work up uniformed brass.
There is really a big difference between this 100 yard target and the two groups above shot at 200 with the forth time fired.
I annealed 1/2 of the brass three times to get a faster full expansion. The third shot fired the brass extraction is tight when the brass is fully formed in the chamber. From here on I most likely never anneal again. I don't run the brass through a die again, sizing or just taper crimping.
Now the hard part, finding a good load coming up.
