anyone know what the bore diameter is on a CVA 45 caliber in line?
i want to shoot some pure lead rounds and dont know if to buy 451 230 gr. or 405 gr 458's.

I doubt that all are the same. You should slug your own barrel. Flatten a round ball so that it is bigger than the bore. Tap it through with a wooden dowel and measure; then you will know.

why?

The "Why" is that manufacturers have no set tolerances for caliber in muzzleloaders. And as tooling wears, bore sizes vary. Green Mountain makes some of the most consistent bores I've seen (for Knight and others). TC bores can vary quite a lot from rifle to rifle.

CVA is not exempt from such variations and may be even more lax with their product. It's hard to imagine a ~$25 Spanish barrel being held to higher standards.

Your best advice is to do just as MLKeith has suggested and slug your bore - that way you will know.

I have to add though, it is highly doubtful a .458 could even be made to go down that bore without a great deal of force. The bore is likely in the range of .448 to .454 land to land. Of those two bullet sizes, certainly buy the .451 - the bullet may not fit ideally but in pure lead it will at at least work.

cva's reply was that the model was .451.
looks like powerbelts or pistol bullets.
