I started all my kids with single shots! They started by simply carrying the unloaded rifle, and I carried the ammo. This was so I could evaluate their safety deportment. When it came time to shoot at something, I would hand them cartridges one at a time.
This worked out very well, because those kids now are 51 yrs old for the oldest, and 44 yrs old for the youngest, and none of them has ever had a safety issue. Also, this tought my kids to make the first shot count! SO! Yes I would say I'm a single shot fan!
I have several Ruger No1 rifles, and sevral single shots by Merkel, and Heym as well. I also like the Sharps replicas as well, and have some of those too.
My father started me off with my first rifle being a mod 67 Winchester single shot .22 lr, and a single shot 410 ga shotgun by Stevens, and I wiped the country side clean of game durring WWII, supplying meat for five families who moved onto my grand father's cattle ranch, in the North end of the Texas hill country, while their men were fighting a war. A job I simply hated
My favorite rifle or shotgun is a S/S double barrel, and have some of those as well, but the single shot will always have a home in my heart!
