A factory sporter barrel can be real good if it's reworked.
From the factory, it's hit or miss. Some are good, some not so hot.
But I've heard if you have a sporter rebuilt, they can be pretty accurate.
There is a guy over there called "nemohunter" I think it is that does
those. They get good reports once he's worked them over.
My 10/22 is a mutt.. I've got a 2000 model stainless carbine, but
my barrel is a NOS blued 18.5 inch sporter barrel. It's ok but nothing
to really write home about. I've been pondering sending it off to Nemo
or one of the others for a overhaul. Either that or consider one of the
bull barrels. The factory "target" models seem to be better out of the box
than most of the sporters.
As far as ammo, mine seems to do pretty well on most all of it so far.
I've used quite a bit of the Federal bulk, and no real problems.
I'll get a few bloopers here n there, but most of those happen when
the rifle starts to get dirty. I've never had a glitch with the good stuff
like mini mags, etc. Mine will start having eject problems with the
cheap stuff when it gets too dirty. Usually after say 300-400 rounds
after starting with a clean rifle.
Mine has the Power Custom trigger parts and pulls at about 2.5-2.75
pounds or so. Also have the extended mag release, and a few other
little goodies here n there like the nylon bolt buffer, etc.
The good thing about 10/22's is you can do nearly anything with them.
But out of the box, it's my opinion that the Marlin model 60 is more
accurate out of the box than the usual 10/22. Or at least that was my
experience. The model 60 I had was a real good shooter. But it's long
gone now. Got stolen years ago..

I bought the present 10/22 off a friend for $100, and all the mods
were already done. Heck of a deal.
