Seeing this I called GM this morning and talked to Kerri whom I've dealt with for a few years now, and she said that's overstating what actually is happening...said the TC drop in barrel business is a good one which they continue to keep going, not discontinuing it as such.
What they have been doing is a sales analysis that's led them to decide on dropping certain barrels in their normal barrel line inventory as they are not selling enough to justify it...like the series of stainless fast twist barrels, some smoothbores, and Flint will only be offered in the .50cal...for example, their website has carried a clearance sale special on stainless fast twist barrels for a couple years now trying to move them out as nobody was buying them.
I have no reason to suspect she was giving me a party line or anything...just sounds like they're trimming back on what doesn't sell...but I also agree with the other post...if you've been wanting a .54/.28ga or a .62/.20ga dropin smoothbore, I'd get them now as it does look like those smoothbores will be dropped from the normal barrel line...I bought a pair of Flint .54/.28ga smoothbores last year, and a pair of Flint .62cal smoothbores this year...have them in Hawken stocks...outstanding barrels for deer, turkey, squirrels, rabbits, etc
