The CVA Optima and the Optima pro are the same guns except for the barrel length (26" & 29"). Barrels are interchangable.The optima elite is a newer different gun and I Don't have experience with it.
Around $250 to $450 dollars, depending on where you shop. This website has all the CVA Optima V2 rifles in stock www.muzzle-loaders.com
It all depends on the model. Most of the time if it says Magnum on it you can shoot 150 grain but most are 100 grain and pretty much all muzzeloading rifles will shoot 100 grains safely. I have a CVA Optima Mag. and I don't think is worth the extra money unless your shooting like 300 yards all the time.
A CVA Revolver with the serial number b52937 could be worth anything. But with your discription it is hard to put a price on it. How much it is worth depends on the condition it is in. It could range from nothing to a couple thousand.

Cabela's or Dixie Gun Works would be your best bet, or gunborker website.
50-500
50-350
Both would work, however a standard 209 should be plenty, and a magnum primer runs the risk of blow-back that could damage you and or the gun.
I will give you $50 for it. I will give you $50 for it. call 704-622-6888 dont let this guy cheat you. if you bought it for $170 i would say its worth at least $110 dollars or so.
