I ordered in some primed hulls from Ballistic Products to try out my homemade roll crimper. I started to make an elaborate cutting jig for 2 9/16, but I found out a 16 ga. hull fits nicely in 3/4” PVC pipe. I just cut a piece to pipe to length and cut the 3/16” extra flush with a razor. In researching recipes the SR7625 powder looks to be lower pressure for good velocities. I tried loading 7/8 ounces, but my 1 ounce recipe makes a better stack height.

Have good luck with Gamebore or Eley 1oz loads thru a 1908 M97 or an octagon breech IJ Champion (pre 1920). Fiber wadding, plastic cases. 1165-1220 velocity advertised. Fiocci 2.5s seemed a bit warm, you decide. Older Rem black game loads were shorter hull, did fine in 97. Why anyone really offers 2 3/4" only when the 2.5-2 9/16 hull is perfectly adequate is beyond me. See Rem OBGL. Found 1 box RST loads, they patterned fine too. Doubles of course is up to you, nothing exciting happened when shooting the Champ.
 
Precision Reloadings roll crimper was said to be better than BPI's. I have BPIs, and an old Lyman, most likely for paper hulls(?). Both worked ok on Fiocci 16 ga 2.5"s, but I never cared for roll crimping plastic hulls beyond one firing. Same Fiocci 2.5" 20 gauge. "Pin" count (more than 1) was supposed to be key. Fold crimp I still use an old Mec 400 with 2 9/16" crimping sleeve, press modified with 2 piece drop tube like 600jr.
