Well I lucked out on the OD...was .630"
My New Alaskan Scout 44Mag takedown with 12" barrel
Good little drybag for when it's together on those canoe trips in the back woods...

29.5" OAL and 18.5" taken down for the receiver. Uncle Mike's 1331-2 sling kit for the front tube. Will allow enough play to twist the tube but is on good when the lever is locked down. Had to shorten the lever a little to make it all work 100%. Going to look for a better side saddle for the rounds. Would have room for 12rds on a velcro strip.
I like it! :D
