Morning Steve, Bill here, no I've never had a bbl. obstruction, & yes I would take it to a smith to remedy that. The only bbl obstruction was just a bullet in the lands & the powder all through the action was worse that the bullet in the throat deal. Way back when, I was into the make every thing perfect reloading, including getting as close to the rifling as possible. Thank God I got out of that stage. I've said before that if it's not a bench gun I don't think ya can tell the difference, me anyway. Now I spend time shooting my rifle to get better accuracy and not, trim,turn,uniform,weigh,check uniformity, . . . . Thanks for the concern and I hope ya have a good week ahead of ya! I'm out. πŸ‘£πŸΎπŸ‡¨πŸ‡¦
