Discovered I have another cartridge that doesn't really agree with the Co-Ax, .218 Bee. I've had the Bee for 25 yrs, Co-Ax for about 6-7. hadn't tried setting up the Bee on it til a few wks ago. Issue is the rim thickness, I have some 25yrs old and fairly new brass as well. I'd ordered the new style enclosed jaws, S and Lg. The brass was sticking under the RH jaw quite a bit, some took some effort to pop out. backed the screws off from 1/4 turn to finger tight, didn't really help. Asked Forster about it. They said jaw rim clearance was .050 on the S jaws, LS may work better as they are .056. My brass is avg .059 to .061, had a few were .063/064, out of what I checked. LS jaw only takes .410 max rim, which would be OK probably, as mine measure .404. Just don't feel like buying them, just for the one cartridge. My old style S jaws work a fair bit better with them, no hard stickers after switching them back in. The Bee is just falls right in that hole in the crossover, between those two jaw sizes. Hazards of a universal setup.
