Gordy, I really can't say.
There was time when I was fairly well up to date on who made what, and what company was really what part of what conglomerate, but since my participation in public shooting has all but died, I don't get to hear the horror stories any more.
I do know CVA has put some very accurate, very reliable guns on the market and it has always been a guessing game as to who actually made what when it comes to this company.
Now I'm hearing that Colt Black Powder Co. (Not to be confused with the original American Colt.) has always been made by Muruko of Japan...not that this is a bad thing.
Muruko makes some excellent guns and was a builder of Weatherby's for years. I suspect their "Colt Black Power" guns are of equal quality.
del asked, "Can someone give an idea of a safe , light load for this pistol. I have some .45 cal conicals that I have shot from my rifle, will these be ok to play with? "
Del, in the interest of safety, I would stay away from the conicals...at least for now, maybe forever.
Personally, I would start with a "lightly" patched round ball, meaning relatively easy to start, and I would use the same powder that Mitch recommended.... 25gr FFFg.
Depending on how 25gr FFFg works, I would start increasing my powder charge in increments of 5gr...
I don't recall reading if this was a caplock, or a flinter, but some reason I suspect it is a capper. Cap locks are fairly easy to see pressure changes in and blow-back, or rebounding hammer, is a sure sign of waaay to much umph....BACK OFF!
As always, with old, untried firearms, safety is paramount...use the KISS method in everything you do until you are intimately familiar with that gun.
Uncle Russ...
