Mike made a video about overboring paint back in 2008. In the video, he said that he though it was best to overbore due to ball deformities, humidity, and extreme temperatures causing barrel breaks in barrels that are underbored. Mike said the .693 was a really good barrel to use. Not long ago, Mike released a video saying paintballs have slowly gotten smaller. He said that his old tips about overboring was outdated, because paintballs have gotten smaller. What's a good overbored size now? I'm looking for a new barrel and I'm unsure of a good size. I'd like it to be big enough for the ball to easily roll through the barrel. Thanks for your responses!

Your stock barrel will be fine for an overbore.

Plus depends on weather. In cali, a 689/691 is best.

.685 seems to be a good all around size.

Just wondering, why would the difference of a open/closed bolt affect the suggested bore size? Not doubting your advice as I like the .685 and .680 bore, but I was just wondering...

Closed bolt as in like pumps. Don't want roll outs, but still want it to be slightly bigger.

Pumps and autocockers are closed bolt. Opens are guns like Axe, Geos, And Luxes.

Would a .689 be good for both humid and dry days in the southern states?
Does anybody know how the cp advantage barrel differs from the normal one? It's more expensive so it must be better quality, right?

It's milled differently to look a bit better. Also, that mentality will destroy your wallet. But no, no real difference. Just like every other barrel on the market. None of the barrels will make any difference on accuracy or preformance. Sound signature and looks is really all that can change, and sound is only by a few decibels, while looks are subjective.

Again, just use your stock barrel to overbore. Unless you want to underbore, there is no reason to even get a new barrel.

I use a .685 barrel, stock, all day every day.  Efficiency gains are minimal underboring with the greater chance of breaks if underbored too far.  Like what was stated before, unless you are worried about rollouts, really a stock barrel is all you need.

 

I don't even use an Apex anymore as it tends to make people longball, including myself.  The last few years I've like being up close to my opposing team.

I just bore match my paint, or I will, once my new BL barrel arrives from the anno shop, and I get the back freak bored.

Is there a limit to this? It almost looks like I could fit two Marballizers down my stock Proto Rail barrel... side by side. I'm exaggerating of course, but I'd say with a ball in the breech end and looking down from the muzzle there is at least 0.010" of daylight above the ball. It seems like that has to be killing efficiency.

What's really killing the efficiency on the rail is the actual way the gun is designed. It's a gas hog

Thats because the paintballs are oblong. Youll see that sliver of light even with an underbore.

All good advice has already been given. See what paint you shoot and go from there, if you change paint brands a lot then I recommend that you get one of the insert/back systems and size it before you play. I had recently first gone with my stock barrel and checked that everything worked right with my marker, adjusted it then changed to my other barrel with an insert sized one over what the paint was and had a 40 fps increase over my stock barrel (I do play in Germany where we play at 220fps so results may vary ;) )
