Hey everyone, CockerPunk and I did another barrel test.
I became curious while reading Mann's barrel test on PBN about a few things.
1. What sizer is optimal for a particular ball
2. What effect does drastic over and under boring have on efficiency and consistency
Our test rig was the following:
* emag
* shooting chrony (accurate to %99.5)
* 500 anarchy paintballs (pretty fresh mid-grade paint)
* bucket
I shot 20 shots through the chrony from each of the following:
* freak kit (12 inches with teardrop front) all 10 inserts - we had a couple of duplicate sizes
* CCM carbon fiber kit - 5 backs
* 4 random cocker threaded barrels we had sitting around including 2 identical Dye 12" aluminum boomsticks
We recorded velocity from each and the results are posted in the following spreadsheet:

Our results indicate that the smallest barrels / inserts / backs had both the highest average velocity and the lowest standard deviation. This test would indicate to me that if given the choice under-boring is your best bet.
I don't know the implications for barrel break increases with fast shooting - that would take another pile of paint and some more testing.
