Stimpy - I guess it is how you look at it. Lyman's 48th edition indeed says that the 38-55 was the parent case of the 30-30 (I looked it up after what you said).
Isn't the linage a straight line from the 38-55 to the 30-30 and then branching out? I was looking at the fact that so many cases said they are formed out of a 30-30 not 38-55. This includes 219 Zipper, 219 Donaldson Wasp, and 25-35, 30 and 35 Herrett among a bunch of others.
whimper - I wasn't thinking that far back. OK, OK the 38-55 is the parent of a slew of cases.
I just saw in Hornady's 6th edition - "Nearly all of today's popular cartridges have roots that can be traced back to one of four parent cartridges. Those cartridges are the 375 H&H, the 30-06 Springfield, the 404 Jeffery, and the 8 MM Mauser."
This does not include the 222 family or the 38-55 family, of course the 38-55 family is long in the tooth and many of the cartridges, it spawned are obsolete or wildcat status, like the 30 and 35 Herrett.
Are you going to include pistol cartridges? All that have been mentioned so far are rifle stuff.
Are you going to make a tree, where the parent is the trunk with all of the kids branching off of that? Or are you just going to make a list with the Parent as a heading?
Why so many questions
