The only way to know is to either mic the chamber or load a ball. When the ball is pressed into the chamber it needs to shave a small ring of lead from the ball all the way around. This is how you know you have a gas-tight fit. If you shoot undersized balls you are inviting a chain fire.

The chambers of my Remington seem to range from .447" up to .451", so if I want to shave a small ring of lead it seems I might want to go with the .454" balls.
Here's my shopping list:
- .454" lead balls
- FFFg or FFg powder
- Powder measuring device (flask or ??) - look for 20-25 grains
- Bore butter or wonder wads
Anything else?
