My pattern testing about 20 yrs ago confirms to me what Dick said. Patterns are better with long cones. The longer, smoother the transition, the better the pattern got in my tests. I tested three cone lengths. A 4" long cone was the longest I tested and it produced consistantly the best patterns.

PS, I would not modify a vintage gun with long cones. The improvement is not worth the devaluation or the cost.
