Can anyone here do it or recommend someone? I have an old H&R 20 gauge single shot that patterns to the left. Like a foot left at 25-30 yards. Yes it's a cheap gun but it is sentimental as it was my first gun 42 years ago and I'd like it fixed.
If you know which way you want to move it, look up and read on barrel bending. This is probably something you can manage.
Get it threaded for chokes, you will love it. I have a 20 and a 12. I shortened mine considerably to use when I am hunting my dogs and I can get around in thick stuff but it shoots great. I would err about shortening it much as it makes many of those guns to hit high and you have to use a very high front bead.I have found my bend to be in the last 1/2" of the muzzle end. Debating whether to cut an in off and let it be cylinder bore or get it threaded for chokes.....
I cut them and and recrowned them myself, as well as replacing the bead, that saved some money. I still had my FFL and I was sending mine to Michael Orlen in Ma. He gave dealers a decent deal and his turn around time was great. He did excellent work. I am sure there are people local. I also hear the guy at Sumtoy is good also.It's 26" barrel, thinking about making it 24" or 25". Any suggestions for someone thread it?
