I have an Ion with a Freak Jr. Barrel. I just got in some RPS AllStar paint and according to a chart I found on the net the average ball size is .686 - .689.

What is the best way to match a barrel insert with these balls? I have a .689 insert so I should be ok but should I buy a smaller insert for this paint?

I assume the best way to check the paint against the inserts is to put a few balls through the insert and see which one has the snuggest fit?

Any help would be appreciated.

Thanks,

Marty
