My 10/22 has a 20" GM Fluted barrel. It is deadly accurate.
Those are damn good barrels, from what I've seen. Is yours finicky? I shot mine today with it's factory target barrel and the damn thing is so finicky it makes me want to throw it out into the woods as far as I can with one type of ammo, and cherish it with the other kind. Seriously, if I tried to use good hollow point hunting ammo in it for shooting rats and gophers, they'd laugh at me. On the other hand, If I use Lapua S/K match grade ammo, the damn thing is going to win rimfire competitions (shoots consistent sub moa 10 shot groups). Mines a biotch though and like a high maintenance woman, likes the finer things in life: It has expensive taste. With this being said,
my "ideal 10/22" would be one that shot good with all kinds of ammo!!!!!!!!!!!!!
