Re: S1\'s Flash Hole Uniformer
When I compared two batches of Norma brass from the same production lot, with and without the procedure, the reamed brass produced more uniform velocities and lower SD's. Unfortunately we have not shot that brass since, although it is on my bench and will get reloaded for another test. My test was limited and I would be more comfortable having done it several times, but the fellow who now has the reamer has tested it extensively and he is a believer.
My partner also bought a uniformer from S1 and he alsolikes the results. He is doing all of his cases, feels that it is worthwhile.
Whatever turns your crank, I will use the little device when I test bullets etc. and want to split Irish Reds.
