Accuracy of Two Piece Barrels???

[Nuwwave]

I have a question or maybe an observation about two piece barrel kits. If the kit allows you to change the bore size of the rear (by either changing the back piece or insert) that will allow for proper paint matching, correct?

But if the same front is used, exactly how accurate can that be? Has anyone done a powder test on a two piece set. Wouldn't the ball bounce side to side when it reaches the front piece because of it's large diameter? Wouldn't you lose the seal around your ball and in turn lose all acceleration when it reaches the front?

Would it be better to just buy a few different bore one piece barrels?

Any ideas?

It doesnt matter that the bore gets bigger after that first 6-8 inches of the barrel. The first 6-8 inches are used to get the ball to its maximum velocity, after that it uses the rest or the barrel for porting to quiet to noise and to stabelize the ball. Most one piece barrels get a larger bore at the last couple inches of the barrel as a two piece does.

Yes. It'll have more control on the ball while it gets up to speed to exit the barrel.

But if the same front is used, exactly how accurate can that be? It'd be pretty accurate. Has anyone done a powder test on a two piece set. Wouldn't the ball bounce side to side when it reaches the front piece because of it's large diameter?

The speed at which a ball is going, and the low friction materials that are used today in barrels, it shouldn't affect it. That's why you adjust your marker's setting to shoot the ball at or around 300fps. And that's why the front of a two-piece barrel is just a bit oversized.

The difference in a barrels bore from front to back is very minimal. It shouldn't be bouncing around like that. What you're doing is a bit of exaggeration.

Would it be better to just buy a few different bore one piece barrels?

It wouldn't matter, really, man. A kit would be cheaper that one piece barrels. And I'd get a kit instead of a whole bunch of extra barrels. That's just me. :-)

Infact a guy has been doing Barrel tests for the last few months and has been posting results on Pbnation, and as soon as he is done he will provide everyone else with the same information. Its very ingenious what he is doing, and very expensive. So probably what ever question you might have about Barrels/kits, hell more than likly anwser, if not allready.

if the first 6 inches is for velocity why is it that the first 6 inches is teh only part that changs tho lol, if its teh last few inche sthat guide and kits keep teh last few teh same....

thats what I dont get, and prolly why my winforce is better accuracy then any kit I have,.

So that it can obtain the velocity more efficiently. The smaller the bore size the more pressure is built up behind the ball causeing it to gain its velocity faster, as well as having something to guide and stabalize it. After the first 6 inches the ball should be stableized enough to where Bounce in the barrel is minimal at most.

If you had a barrel of the same bore size which it was Equal to or less than the size of the ball the speed, accuracy and distance in which the ball would travel will be decreased. IE: More friction

Of course this is my own speculation and what makes sense to me...
