Isn’t the 201 basically a dumbed down Parker Repro (minus dolls head, etc.)?
I don’t think I’d shoot ultra high pressure steel loads in a 201. I personally don’t think that the locking system is robust enough to take that kind of continuous punishment. At least a BSS has two locking lugs.

Moderate pressure & velocity bismuth/TM would probably be best to use in that gun.
