FWIW
My CZ455 did half inch at 50 yards, sporter hunting rifle w SK Rifle Match ammo.
Hated the safety so got a 457, but in .22 magnum.
Now am looking for an older Anschutz 64 for a hunter in .22 lr.
Was gonna try NRL22 so picked up a Savage MKII TR. Only tried it w Fiocchi HV, new gun had a box of ammo, break it in.
It too did under .5 at 50 w that stuff. Of course thats the only box I had LOL
The 457 sporter and the MKII TR both had MSRP at 600.
The Savage to me is a clunker, but it shoots good enough to warrant further evaluation.
I got a DiP trigger guard, EGW base and rings, and slapped a 6-18X Freedom VX on it
A little chunk of money in ugly setup.
Id say scope and rifle, medium price/value..........runs $1-2K
SK Standard Plus is avilable here and its 90 bucks a brick.
Trying for a little better accuracy proly means more expensive ammo, better triggers and optics.
