Alright y'all, I've done a quick search on here and didn't come up with anything so I'm gonna ask the question. I have an 1100 mag with a Hastings barrel chambered in 3" on it, which has interchangeable chokes. I noticed this barrel also has gorrves cut down the barrel. Now I remember seeing something on here a good while back about folks having grooves cut inside their barrel, but I cant remember anything about it. I was wonder if anyone could tell me anything about this barrel? I'll have to measure it, but I'm pretty sure it's 28" long. I bought the gun from a flea market about 7-8 years ago, and wasnt sure about the Hastings barrel, so I bought a Remington barrel to replace it. I guess I need to take the choke out of my Remington barrel to see if it will screw into this Hastings barrel, unless someone on here says other wise. Again I would appreciate any information you all might could give me on this barrel. Thank you for your time and help.
