The reason for brass over plastic? While one could make the argument of long term of economy; it is mostly because I like them and it is affectation for the most part. They are easy to reload ( minus the sizing issue) and I have some that have been reloaded near fifty times,with other than fire forming to the chamber size, no ill effect or signs of wear.
For my 12ga 2.5 inch I near exclusively use paper hulls, roll crimped on an inexpensive harbor freight drill press. I have simplified it further by staying with two paper hull types (federal & cheditte), two powders (International & Longshot) and limited wad variation. I still have some cut down plastic gold medal federal for my stockpile of SR7625 & 4756, but have not loaded those in years.
Why paper instead of plastic? I believe they more easily roll crimp for a excellent look. Like the RMC brass hulls, a little affectation too. I find fellow hunters are fascinated by the RMC or short paper hulls when I show them.
While I have RMC for 12, 20, and 24, most of my RMC use has been for 16 ga. When i thought RMC was going out of business I brought far more RMC than I should have, but they will outlive me and possibly the next couple of owners too.
