A warning about Undertaker High Density Choke tubes. I ordered the Rem Choke model and was only able to thread it in a couple of turns. I contacted Hunter’s Specialties and they did offer to replace it. I shipped it to them, but after checking around, I see others have had that problem also. It is a bargain at only $20, but I am not sure it is worth all the trouble. I am going to test it with some Federal HW 7’s since I have gotten this far, but I am not sure I would do it again.
