I just went thru the very same thing. Had a Ruger 77/22 that wouldn't hit a barn from the inside. Ordered a CZ 527 from the LGS. Single set trigger, comes with rings
Took about six months, and got it a few months ago. Haven't shot it yet. Need to sell a 6x20-40 Nikon scope I have so I can get a new one, probably a Zeiss Conquest 3x9
I frequent another forum (Varmint's Den), and I asked the same question here and over there. CZ was the number one response by far. Most of them seem to shoot in the 1" range. Couple guys had Browning Micro and they look really nice and shoot better than they look.
I personally just can't warm up to Savage. Reviews seemed to generally good on them. Once in a while you"ll find a Ruger that will shoot well, but for every good one there are probably five bad ones.
The European 22 Hornet chambers are a bit better, accuracy wise, than those made in America. I am afraid I forget the exact details but it is the difference of how the two allow for headspace. It is not an issue if the owner hand loads as he can tailor the cartridge to his chamber.
Biggest culprit on Hornets seems to be that they headspace on the rim. If there is ANY slop in the space between the bolt face and the area of the chamber that holds the rim, it allows the cartridge to tilt pointing downwards in the chamber. The bullet skids off the bottom of the barrel when it's fired
I suspect the accurate Rugers have a tight tolerance. Bad ones have slop. More slop means the bullet whacks into the barrel harder, distorting it more. Better guns (CZ & Browning) hold tighter tolerances.
You can over come this by using certain bullet and loading combinations. A 40 grain V-Max has a rather blunt profile. It can usually be seated out long enough that it will still mag feed but the bullet seats on the lands when chambered. This holds the bullet/cartridge in alignment as it is fired.
You can also space the sizing die from sizing the whole neck, and only partially neck size. This leaves part of the neck the same size as the chamber, which centers the round
Took me a couple years to get all this info figured out. Sold the Ruger before I had this info, but by that time I was tired of messing with it.
Your easier alternative is to get a .221 Fireball. Almost identical performance to the Hornet but less drama. It does lack the "cool" factor though
Hornet brass is tissue paper thin and doesn't get many loadings. You can do a little better if you anneal every three firings or so. Otherwise the necks split. I'n gonna try to get a Lee Collet Die so that only sizes parts of the neck.
