Hey Guys,
Thanks for the input. I wanted to find out about where I should be pressurewise. Even though it an "early fluid steel" I figgured it might be pretty soft material and you guys confirmed it; certainly not Remingtons Ordinance Steel. I think most of my handloads will be in the 1-1/8 oz range, maybe 1-3/8 oz if I try for a turkey. Do you think RST shells are low enough in pressure if I wanted to just buy some?
2-Piper, you're right about the various shell lengths in 10 ga. I have a reprint of M Hartley Co catalog from 1902 or 1903 and they list the 10 in several lenghts. I think the heaviest factory loads listed were 1-1/4 oz.
