I've done it.I also use a 22 rifle sometimes.But haven't used my 22 rifle or pistol in years.I got an old browning,heritage rough rider,and a ruger wrangler.But now I just let the kid have at them.He uses a shotgun.And when he isn't with me I just let them go for somebody else.
Been packin a Colt Woodsman for 20 years, and like you, my dad had a Ruger and would take their heads off. What got me started was shooting one with my 270 and forgetting about the drop between the scope and barrel. Aimed for the head, and hit center mass, All I could find was a foot and some feathers!
i hope our grouse population is better this year, last couple years I barely saw any, I have shot grouse with my ruger 22Lr revolver, a glock 26 my bow, shotgun, and many with my deer rifle. good camp meat there
