need info on baikal choke tube diameters

[hornsurgeon]

anyone here have a baikal 12ga with choke tubes? i'm looking for the inside diameter of the barrel without the choke tube installed. i'm working on a project that involves removable full length barrel inserts in 20" barreles and need that dimension to determine if i want to order one of these guns to use as my platform. the stoeger coach gun appears to be a little large in this dimension.

thanks!

Every inside dimension in a shotgun barrel is different..
You need to have stotgun in hand to get the right inside diameter ??

what i need to know is what the inside diameter is with the choke tube removed. i don't need to know bore size, i need the inner diameter at the muzzel with the choke tube removed. this should be just a fuzz larger than the outer diameter of the choke tube. it's a standardized dimension for that choke tube design.

just like all remington shotguns using remchoke will have the same inner diameter so they can accept the remchoke tubes, and remchoke tubes are also all going to be the same in outside diameter.

Will the diameter of the choke tube get you close ??
Is the tubes in a Baikal interchange with any other ??

according to the carlsons website, it's a standard truchoke system. the outside diameter of the choke should be close enough to get me started.

My Truchock Reamer is .796.5 ( from threads to end of barrel)
.777.3 ( from threads to bore )
Tap .794.0

what do you charge to ream/thread a double barrel for chokes?
