HULL 20ga 2.75"12mm (NEW) PRIMED p/100 YELLOW 2300c

These hulls are as advertised, an unskived hull and therefore a full 2.75" length, maybe a touch more. They are easily skived with a rotary skiving tool, large kitchen knife or appropriate size broad head. You may wish to measure length and determine if they are a uniform length before skiving. If you have been reloading old age hardened American hulls, like Federal or Remington, like I have, on my 1983 MEC 600 Jr. When you switch to using these you will need to adjust your crimp cam up (clock wise) and possibly the die height, in order to avoid a base kink or bad crimping. These are new soft supple hulls that will last a long time when loaded properly. Do not let operator error deter you. I did not adjust my cam for the first hull and did suffer a base kink. By the third hull I had my crimp cam dialed in and my die height slightly adjusted and did not suffer any further kinks. There is a very slight amount of castling to the crimp rim, That I have tried to adjust out, but I do not believe I can tune that out completely with factory MEC pre-closure or crimp die. I believe I would need to upgrade to a Ribassatore style pre-closure die to get the ultimate factory crimp. These also seem to have a primer pocket that is snug enough that it will hold a 209 primer without swaging the primer pocket, but I still swage my foreign made hulls for peace of mind.
