Caledonians and Milbro TR go well in my older pistols as do Falcon Accuracy Plus.
Best bet is to compare the ones you have with a few makes.
That's how I stumbled on TRs for my S&W 78G which was boxed with a tin of SW pellets.
I have a big selection of pellets!
Maybe if you put a pic of the HC pellets on here it would help or email me a pic for shape comparison.
Good luck with this rare pistol.
