Underboring with fragile paint

[Orion3]

I've been reading and watching quite a bit on the subject of underboring and am pretty convinced by what I've seen. Up until now, I've always overbored, so this is a fairly big change for me.

I'm waiting till the end of the month to pick a new barrel set to allow me to give it a go properly, but before then have a question for anyone that is already underboring....

If you are underboring with fragile paint, do you still see as few breaks as when overboring?
I understand that when overboring paint can bounce in the barrel but is this worse (or better) than tournament paint with brittle shells being compressed as the ball is fired?

Appreciate your feedback.
Thanks!

I've always overbored with fragile paint, I would have thought underboring would be just as bad if not worse for fragile paint.

Overboring is only usefull when paint isn't regular.

Else you can just "underbore" a little bit.

I choose my barrel by being the bigger bore possible still having the paint not rolling though (habits coming back from cocker and pump guns)
You break paint when not regular, but never had issue with Hellfire / Pro / Evil / All Star / ... doing it this way.

I have a .688 Boomstick and fire everything out of it.....

If you want to spend the time matching up just match paint to the barrel that gives you a ring of light around the ball if you pop it into the back of the barrel.

Don't underbore as you will just break paint.

Big ball + Small hole = Soup

Doesn't work that way....but I've personally yet to try it with really fragile paint.

Simply - the uniform pressure exerted by the barrel on a spherical paintball means that the paint doesn't break..just squeezed.

The results are better efficiency and shot to shot consistency - allows you to drop the pressure getting more shots per tank with the same degree of accuracy you get from overboring.

My point/question is - normal paint gets squeezed and delivers efficiency and consistency, but will fragile paint break first; rather than uniformly deform?

i've been looking at underboring too, having always overbored....

the trick seems to be getting it to be the smallest amount of underbore possible to get the ball to just not roll/blow through. in that case if the paint is fresh enough the shell should still compress the tiny amount needed without cracking.

i think too much of an underbore, combined with overly brittle or out of condition paint may stress the shell to much.

So we have had reccomendations to Overbore, bore match and under bore . .

wut.

Great eh!

I do this on my nt ...
Dye barrel in .688 and shot anything ....
Work same ....

I would only recommend to match bore if you have a marker with close bolt (cocker , ...)
Else a .688 is good

I overbore.

The accuracy advantage is slight at most. The amount of shots extra in the tank is a small number.

I would rather not risk blending paint.
