If cockerpunk happens across this thread, maybe he can fill us in on the brand and brittleness of paint that he used to test barrel breaks.
Of course, I'm more interested in the performance and reliability of higher quality paint that flies straight, not cheap rental paint or house paint. Paints of interest to me include makes such as high quality rec paint like Grafitti, GI 4 Star, etc. as well as uber-brittle tournament paint like Redemption, GI 5 Star, etc.
I have so many questions about your test; Do you recall the brands of paint that you used in your test to achieve such significant results? Any chance you remember what the drop test results for said paint was? Do you think I could replicate your results using HK Supreme, which breaks reliably in a drop test on drop 1 from a height of 18"-36"? What was the approximate temperature during your test? Was the same gun and loader used throughout the test? Did you adjust your velocity to the same fps each time you changed bore size?
It was a while ago, but I believe the paint on our test was Draxxus. I can't remember the grade, but the seams were really weak for that batch. They were a 1 drop break for most of the paint. We only tested the drop from shoulder height so I can't attest to how low it could go and still break. The hopper used was an VL Egg. We didn't want something that would provide a force fed ball into the breach. The weather conditions were cool and dry. I suspect it was about 50 degrees farenheit. This paint had a flaw that allowed a test like this to exaggerate any results. The 50:1 ratio is pretty exaggerated and doesn't represent how most paint will function in similar tests but it does highlight a potential issue. I suspect any really brittle paint will give breakage results but may not give the exaggerated results we had, because of the flaw that our paint had.
The paint that broke on every shot was a random paint that someone gave us. I don't know what it was. It was just brutally brittle.
I used the results for personal play style. All tournaments going forward, were played using overbored barrels in all instances. I played several years of X-ball and can count on 1 hand the number of ball I broke in my guns using overbored barrels, even when others using the same paint were having multiple breaks per game.
Except for the Automag in front, its usually the man behind the equipment that counts.
