Thanks for the info on gaps. Anyone else feel free to contribute, as I am curious. Going back, I measured my feeler gages with a caliper, and the very edge, the part I was able to get between the cylinder and barrel, on my .014” gage was actually as low as .010” depending which part was measured. Based on this, and comments to this point about gap in other top breaks, I’m satisfied that mine are probably ok to shoot, though I will be cautious taking them each through their paces.
