Is it possible to mill the "drop port" opening large enough to eject a 30ppc and a 30BR? Would it cause any problems with the 6ppc? It sure would be nice if one port had the capacity to cycle all 3 rounds.
Just askin......
You only have to slightly open up the neck area of the drop port. The length works out fine as is. I also had to change the angles on the drop port in the stock to make it totally reliable with the 30BR. Mainly this involves making the rear angle a bit closer to vertical and making the outlet oval instead of round. I have a PPC bolt face and rebated the rims. Fortunately the brass lasts just about forever if you anneal it every now and then.
