Paintball barrel selection

Mike from Techpb.com had some thoughts.

Barrels impact the gun performance a lot. Tech PB likes these barrels in Florida where it is hot and humid.

Boring a ball is when you take a paintball and place it in several barrels until you find one where it it just large enough to get stuck about half an inch down the back of the barrel (off the gun).  This is the traditional way of picking a barrel since it uses less air in the long run since air is not escaping around the sides of the balls.

The case can be made that traditional boring isn't good because some balls later on will be compressed and more oblong instead of circular or swell throughout the day. If they get stuck in the barrel, they can explode in the barrel. When that happens, the paint gets on balls that come out and causes them to become innacurate for quite some time. Shooting though it doesn't always clear it out. You have to clean out your barrel with a barrel swab or squeegee.

Industry standard is .689. (Balls can break inside it though.) Traditional boring may have you select around this size.

Planet Eclipse uses .693 and people like their barrels.
BobLong Marq .691
 Dye UL Two piece .692
.693 CP 1 Piece 14"
.694 Bob Long Marq two piece (if humid)

Overboring means less broken paint. Oblong balls are less likely to break.

If you bore in the morning, and it gets warmer, the balls will get larger.
overboring means better consistency, though a bit less air efficient.
The Pros overbore.

12-14" barrels are the standard. Longer than that, like a 16", and the ball may just be bouncing around.
