I shoot a lot of doubles for practice.I use the universal , there is a learning curve , use a scale and weigh often.
I weigh every 50 rounds , I have more problems with fine powders
This is a DUAL MEC BUSHING BAR, saw this on ebay, long time ago.Link to double bushing bar on EBay:
The seller makes them for single stage and progressive. Good guy to deal with.
Any for the Redding 16 / 32, or Savage 630 ?I have all of the above setups and all have their plus and minis I probably a thousand bars of various kinds and sizes that I have collected since 1974 Mec, Herter's, universal, homemade Various bushings and many hand filed out that just look terrible, buy another bushing or bar instead of grinding on them.
