PMI or RPS W/ J&J

[tippymann]

I have a J&J Ceramic and I am wondering if PMI Premium or RPS Big Balls will work better. As of right now I am using Proballs, but I am trying to test around with other paint to see which is the best match, and I have found both Big Ball and Premium for cheap. Thanks to anyone who can help.

Well, im not sure how the bore sizes match up on the two... But great paint and a good barrel will probally work fine

actually...

nobody could really answer this question for you.....

J and J barrels do not come out with identical bore sizes from the factory.. you must measure yours, and then we can judge for you.

mine is .689, and i have shot rps premiums decently... but by charts, the bigballs would fit much better.

Thanks for your replies. I was wondering, since I haven't played for very long, what I could use to get an accurate reading of the bore size of my barrel.

RPS PMI premiums are the same size as RPS big ball. they are both med bore and should shoot the same.
