I can't decide if I want to try the AI route or not. This will be going on my 12FVSS that is currently a 22-250 but is in need of a new tube BAD! Will be used for a variety of shooting i.e. targets, long range steel, crows, etc. My concerns are barrel life for the AI and what twist to go with w/o spinning it too hard. Have heard they tend dirty up fairly quick and require more frequent cleanings. Thinking maybe just stay with the rem 22-250 but man that AI case looks nice!
