I was thinking of putting choke tubes in my 90t but I'm not sure who I should send it to and what kind of tubes to put in it. If anyone has any info they are willing to share I would appreciate it.
Why alter one of the best fixed, factory choked barrels ever produced. It may get you an extra bird, or two until the confidence again goes back to normal. Then you have to maintain them with grease, and cleaning on a regular basis.
Seems once you find a tube you have confidence in, it is what stays in the barrel all the time anyway.
Not many originals left. Spend the money on a good book of how to build confidence, or one of the many from the big experienced shooters. JMHO
