Promaster chopping

Hey guys, haven't played in a while, but while I have some time to kill thought I'd see if anyone had some input.

So I picked up a Promaster a little while back, used it one day earlier this Fall and it shot well, but had a tendency to chop one or two out of every two hoppers. It had fresh batteries and I was using a VLocity with the eyes on. What I think happened at first was there was a break and a piece of shell got stuck over the eyes, but after that got cleaned out it still chopped once in a while.

Was it the paint I was using? Should I adjust my board? Everything had new batteries and was cleaned before using, just looking for some thoughts.

Thanks

Is it really "chopping" the paintballs? Or are the paintballs breaking in the barrel?

I'm not 100% sure to be honest. It's possible that the first paintball broke in the barrel and then caused subsequent paintballs to seem to "chop" afterwards. The sheer amount of paint that found it's way into the lower chamber makes me think it was a chop, though I could be wrong.

Any idea what your velocity is? Is it consistent? What kind of reg are you using?

Velocity was around 265 since the field limit was 270. I was getting acceptable consistency, probably +-8. I was using the stock reg and a nitro duck 68/3k. I haven't changed anything since playing last.

You may want to check on the velocity again, the only thing that make mine chopped was when my stock reg get too dry and the velocity suffered - so the velocities fluctuate and balls keep hitting each other inside the barrel. What if you try to fire without the barrel on? That at least should eliminate whether or not your barrel is causing the problem of it is is something else.

You may want to check to see if the detent is loose or anything like that too?

I was thinking something about the reg myself so I'll go through and replace/clean everything and see how that holds up. The paint wasn't the greatest either so I'm sure that didn't help. I cleaned the detents after the first set of chopping so they SHOULD still be decent. Thanks for the ideas man I'll give her a once over when I'm done with finals.

depending on your vlo settings, you could have been feeding a ball and a half, but that would have given you lots of paint in the feedneck area. Most chops I get are from misreading eyes (fairly common), serious pressure fluctuations (next to most common) and very brittle shelled paint (least common)

How would one know if their eyes are misreading? I doubt it's the paint I use relatively thick-shelled stuff. The pressure fluctuations are a definite possibility, but they don't seem extreme enough to cause serious chopping issues.

if it won't fire when the bolt is back, it should be good. Also check to see if your paint is super small. that can give you issues also.
