How much does .001 really matter?

[BlackNight52]

Ok, I have a stock Spyder Xtra right now and I'd like to at least one upgrade. I'm thinking I dont need an agitating hopper (at least not now) since I normally like to pick my shots and not just shoot out 20 and hope one hits. Anyways, I'm trying to decide what size should a CP 1 Piece should be. I try to stick to the cheaper paint (I dont feel like spending $50 when I just want to have some fun :P). I normally use Zap paint (Sport) which, according to the size chart is .690. And (if memory serves me right) a CP 1 Piece either comes in .688 or .691. I've heard that just rolling a ball down the barrel will do the trick, but (IMO) it doesn't matter if it rolls out or not, its if it hits the target.

My questions are:
Assuming I get a .691 barrel, can I still accurately shoot .688-.691 balls? And (topic) how much does .001 really matter?

Thanks for any help and for just reading~

you can probably shoot those fine, and the .001 i dont think it really matters THAT much, but if you get a perfect fit on the paint to barrel match your shots will be much more consistant.

also... you want to be able to blow the paint through the the barrel without tons of force, not have it roll through

hope this helps

depends on the barrel your using some barels are really paint senitive and some arn't, like my PMI multimetal (worst barrel) if i put in PMI Premium it works OK but if i use Diablo Blaze (only .001 higher) it breaks them, don't worry i don't even use that thing anymore

The cp comes in .685, .689, and .693. Get a .693 cp 1-piece from criticalpaintball.com .

Barrel systems were designed for closed bolt guns. When the bolt closes the paint is now in the start of the barrel. If the barrel is too big the paint will roll out, or partially down the barrel. This will need to not having that first shot, or greatly affecting your velocity. The solution to this problem is a good paint/barrel match. Which would mean buying 5 barrels, or getting a barrel kit.

Open bolt guns don't need paint/barrel match cause they have detents to keep the balls from rolling down the barrel. So you can buy a large bore barrel (.691, .693, or .695) and use that one barrel for almost all paint (unless its freaking huge and need a .697, which they don't even make, so that means your paint is bad).

Now the advantages of a good paint/barrel match is more consistant chrono readings, and slightly better accuracy.

With a large bore barrel your reading may be an extra +-2 and from end to end of a 180 foot field, your groupings may be 1" to 2" larger.

Paint to barrel isn't as important as people make it out to be. For an open bolt marker buy the larger bore and you'll be just fine.

Those numbers are averages and you will find variations of +-.001 in every case.

Hey, if you ever run out of air and your paint doesn't match your barrel perfectly, you can't run around using your barrel as a blowgun.:laugh:

Will paint like .688 to .690 work good on a .693 cp 2 piece on an impulse?

A good match will affect the consistancy some. It's nice not to have the balls bouncing around inside the barrel. But the paint I buy varies more than .01 sometimes! So it's not a real big deal for me. Getting a .693 will assure that your paint won't break inside the barrel(within reason). I'd get the standard .689 that size seems to work very well for all around shooting. However I may end up getting a CP kit for my EVO since that perfect fit helps with accuracy and consistancy. Correct me if I'm wrong people!

Paint size charts are estimations. Depending on the weather, they can shrink and swell. A few diff bore size barrels to cover all the paint is a good way to go.

if this were the case, why don't they make closed bolt markers with a second detent to keep the ball from rolling out.

cuz the ball would already be in the barrel? anywayz ppl said that it would be a waste of energy/air or something like that.
