These two conflict. Consistency is a cornerstone of accuracy. Ignoring all other factors, inconsistent velocity between shots will have variation on the vertical axis. In other word, faster shots will hit higher than slower ones. The more consistency between shots the less deviation there will be as a result.
1. What bore/paint size are you using?
2. What is the average temperature where you play?
3. What length barrel are you using?
4. Have you noted any improvement over your larger bore barrel in either accuracy, consistency, or efficiency? If so, describe?
5. Are you experiencing an increase in paint break?
1: I use a lot of different paint. From various tourney grades, to mid and cheaper, to white box.
2. From below freezing to over 100. One tourney I played where it started in the 30's and ended over 60.
3. Typically 14 or 15 inch.
4. If the forecast calls for a typically consistent weather, then I'll chrono and shoot a bunch of paint through a few different backs and see which one is doing the best that day. If the forecast says temps are going to rise significantly throughout the day I'm playing, then I'll do the same thing with multiple backs, but with overbore. That being said, I prefer to underbore. I typically see more consitancy. I don't care so much about efficiency since I usually play speedball and don't take out enough paint to drain my tank, and filling between games.
5. Only time I typically see barrel breaks when I underbore is when the weather is changing fairly quickly and the paint is reacting.
