Anyone have a link to info on the chamber specs on these? I picked up one for a Zues to play with and noticed a 80 ELDM at 2.540 COAL (was staying close to MDT plastic mag length) and 2.000 CBTO drops right in and easily does the pinky nail removal on bare barrel . I plan to measure it out however I'm thinking this needs 88-90s to even be close to the lands, or exceed the current mag length?
