What part of Wyoming are you in. There are several Rifle Clubs affiliated with the Wyoming Rifle and Pistol Assn, and CMP. Most put on rifle clinics for little or not charge. I believe Lander charges a modest fee, I run one in Weston county for the Weston County Sportmans Assn. and we dont charge anything.
If you let me know what general area, I'll give you the information on clubs in your area. If you would rather, you can IM me for the information.
DONT GET RID OF ANYTHING UNTIL YOU FIND OUT WHAT YOU HAVE AND IF IT WORKS FOR YOU. You dont want to ruin grandpa's rifle.
PS. You sound like my grandaughter, I let her use my 257 Roberts this year now it appears its automaticly hers.
