I have used Mec press's for years and currently load 12,16,&20 all 2 1/2 low pressure using a Mec sizemaster. IF you are going to load the shorter shell there is a "short kit" you will need also. I have a friend who was reloading paper hulls all 2 3/4 but they didn't reload very well. The are nice to hunt with esp when roll crimped. theres something nostalgic about being afield with a damascuss 0 frame 16 and roll crimped paper hulls.
Brian Erickson at New Era Ammunition is doing some work using a 2 inch roll crimped 16 paper shell. These are really cool. Basically its a 28ga load in a 16ga hull. Great on grouse, Woodcock and Quail
