I don't know if this is the spot to post this or not. If it is not where I need to post this, please let me know where I need to. I am a Hunters Ed and NRA Certified Instructor. I am looking for any burst barrels, bulged barrels, etc that I can use for class. I could use this for those classes along with Boy Scouts and 4-H also. I would be willing to pay shipping to me for these items. If you have anything that you think I can use in class, please let me know what it is. Thanks for any help that you can give me on this.
