For anyone that will listen, if your gun has ball detents you should always use a 691 or 693 barrel at events

Good call! I always overbore at Huntington Beach; .683 across the longer axis normally puts me in the 689 to 693 bore area....the paint always swells faster than we can shoot it.

Guns without detents need a tighter bore size to keep paint from rolling down the barrel. A gun with detents will keep the ball in the chamber for you, so upping your bore size will cut down on barrel breaks. You can usually get away with a tight bore but event paint is more brittle than practice paint. Might lose some efficiency but most of us have air next to the field so that's becoming less of an issue.
