Overboring question

[JeeperCreeper]

Grab some GI 3 star. Thats all you need to be inaccurate. I feel like a tighter bore with oblong paintballs is going to be less accurate than an overbore. Other things you could try: leave broken paint in the barrel. Use a gravity hopper on a fast marker with no eyes and just send 'er bud. Or try a tippman flatline or Apex barrel tip, those things will give you a wild spread (that might be the least sarcastic suggestion actually)

As you can tell from all the comments, we tend to look for more accuracy, not less. What you seem to be looking for is something that occurs naturally. Even high precision firearms have a spread (MOA)

Not really sure why you would want that but basically you would want to do the exact opposite of the best boring practices.

first get the crappiest, most dimpled, non round paint you can find. Then you want to get a bore size that averages out to a bore match, if you get the right crappy paint some balls will be pretty tight and some will fall through, either way this you have the least consistent relationship between the plant and bore so you will have varying effects on the balls.

generally an overbore helps reduce inconsistencies in relation to the paint touching or not touching while (or so it is claimed) reduces breaks, but you sacrifice efficiency. Underbore (.003-.005” under the perfect match size) is the most efficient, but there’s arguments based on the data that it can slightly reduce your “accuracy” however I am not sure that really plays out in the real world with two piece barrels where the tip is massively overbored; the claim is also that it can increase breaks but I believe someone did some research on it and showed that there was no statically relevant change to support that claim.

so yeah TLDR, get a close to a “perfect” bore match on the shittiest paint. And a one piece barrel probably would also increase that since you could more easily get the effects of the uneven seal releasing at the end of the bore which could drive the balls off line slightly.
