Way back in the 60's,there were a lot more 50 ft indoor ranges with Jr NRA smallbore programs supported by the Director of Civilian Marksmanship.
That has changed to the CMP,Civilian Marksmanship Program.
One group that has some of these programs is 4H.
Maybe,,if you do some checking,you can find a smallbore program to participate in.
The CMP has a website and a rifle marksmanship book.
Another,if you can find it,is "Position Rifle Shooting"
Others here may make more suggestions.If your dad is into it,maybe,referring to what these books have to offer,he could coach you some.Understand,I cannot write a script for your Dad,and I don't know him.Learning to shoot,a coach is very useful.
I agree with the suggestion to dry fire.
You can sling up,find good position,natural point of aim,breathe,squeeze,and call your shot on a target.
Not talking about just snapping the gun at the wall,but doing it all,just not putting a round in the chamber.
Hey,kilmanjaro,thanks!
