Asking which gun to buy is like asking someone which religion is the best or which political party. Lots of great replies but I if you just like plinking a 10-22 is hard to beat. If you like something with a little more muscle a 223 like a Ruger ranch rifle or any ar15 is lots of fun. ~~~
I like this response as much as any. Choosing a long gun is as much how it fits your body as what caliber it shoots. My personal favorite is the Ruger
Mini-14 Ranch Rifle. It is available (or was, last I checked) in 223, 30 Russian, 9mm pistol and a "drop-in" 22. Many "short action" rounds could be fitted, with a little finagling of course. I had to have a retrofit stock 'cause I'm so big. My wife is 5 ft nothing, the stock stock was a good fit there.
The key to me was the mechanical action. I have had experience with the early M-16 and swore
at it more than I shot it.
I don't like the M-16. I went through boot camp with an M-1, had some experience on a range with the M14.(a grandchild of M-1) The newer M-16s are sworn
by rather than at, but my size may be a factor there. I'm 6'3" with long limbs. A Medium Tall shirt is a poor fit, the sleeves are too short. Call me a knuckle dragger,
when I'm walking. The AR-15 is a civilian version (semi auto) of the M-16, to my understanding.
The Ruger Ranch Rifle has a "Williams" action, derived from the M-1 Carbine and M-14. It works, period. If it gets mud or sand in it, you rinse it in a creek and it's functional again. In the 223 action, a magazine for an M-16 will fit. It is a well balanced rifle, but has no recoil supression. With a hot round, you feel it.
I have "disposed" of my firearms, except for shotguns. There's not much left of my
one eye now, I can't see well enough to aim, even with a scope. Which I never depended on anyhow. There are other similar long guns around, the Marlin 9mm carbine for one. But I personally come back to the Ruger Ranch Rifle in the end.
That's my opinion though, that's all it is.
