My dad just got an older used mossberg 500 turkey/deerslug combo and i went to pull out factory choke and it will not move hit it with every kind of oil for that purpose still cant get it to move searched forum have not found an answer. Anybody know a trick ?
It sounds like it's a flush mounted choke, correct? There could be a couple of reasons that it's stuck. It could be rusted in place or it could have expanded and be locked in place. Many times, if it's rusted, you can allow the muzzle to soak in some penetrating oil, WD-40, Kroil or some such and then you may be able to remove it with a good choke wrench. Patience is the key.
If it has expanded into the threads, that may not work. If you try too hard, you may damage the slots in the choke and make it even more difficult to remove.
You may be able to heat the muzzle, as has been suggested and that may work to loosen it but I always have a bit of concern about too much heat damaging the barrel. Unless you have some experience doing that, I'd be very cautious about trying it.
If you have access to a local gunsmith or if not, if you're willing to send it to one, it may be money well spent. They have tools and experience that can help greatly in that process.
Thanks,
