Bill,
This .38-50 Rem Hep has been an interesting ride so far finding dies plus with all shortages for components like brass. I did manage to find .30-40 Krag Win brass at a fair price of $27/50 Hornady is none existent and Rem is discontinued. I managed to get 500 cases with the same lot. Man some places they are asking $3. plus a case for fired mixed cases.
I annealed a few and used some unique powder and filled 5 cases with Cream of Wheat and fired them in my .40-70 to see if that load would blow the neck and shoulder out and it did in fine shape. The cases looked like they were made straight wall, no wrinkles. The case necks are thicker and run a very consistent .012"+- a 1/2 thousand I'm well pleased with that.
I can see that fired in the .38 -50 chamber all will be well. and I don't think a die will be needed for sizing.
I called all the die manufactures for a taper crimp and sizing die and all gave the thumbs down except Dave at CH-4-D but he could not give me a time frame when he would tool up for it.
I'm going to make a reamer print for a taper crimp die as soon as I get a chamber print for the ordered rifle then I will have PT&G make a taper crimp reamer for this caliber so I can make my own die.
Arnie has been very helpful with information with this project. Arnie gave me two bullets he uses but for the life of me I misplaced them or the cat found them to play with.
