I am in need of a bore lap for a 28 ga. I know I've seen lead laps in books and think that this would be just the ticket for my latest project. Anyone know of a source for one? Brownell's sells a brush thingy but I've used it on other gauges with limited success. They are expensive for what they do. Also I need a reamer made for the chambers/and bores for 28, I can get the appropriate measurements if anyone has a source for this custom tooling?
