Re: Info on 22 rifle accuracy
When it comes to new match 22LR target rifles you pretty much get what you pay for. Anschutz is probably the leader in this respect in the $700 to many thousands of dollars. You pay extra for tricky Olympic style stocks (totally adjustable) and for fully adjustable triggers (dual stage with ounce level let offs).
If it is a more normal rifle you are looking for, the bottom of the Anschutz line Silhouette rifle is set up for scope mounting with the correct stock for that and can be had with a better trigger that is a fully adjustable two stage. If I had to shoot in any contest that allowed it, that is the gun I'd take to the game if I could not afforded the better ones.
In the CZ line the CZ 455 Varmint Precision Trainer might be an option. But I can tell you it may not be in the same league as the Anschutz Silhouette. The trigger, while adjustable, is not adjustable to the same degree at all. There may be some bedding required for the CZ too. The Anschutz is good to go right out of the box and is priced around the CZ price ($900).
There are many used guns that might do the job but they too may take some trigger work and/or bedding work to shoot with most Anschutz rifles out of the box. You'll have to do some research but for some time years ago Anschutz was imported by Savage with Savage's name on them. That might be a rifle to try to find used.
If accuracy is what you are after then you'll have to pay the price. You'll not get an out of the box CZ to shoot accurately out to 150 yds, in my opinion without lots of work. The CZ 455 Varmint Precision Trainer May (??). When it comes to guns you intend to use in the field or for plinking, other guns have a hard time competing with the CZ's. The CZ's, across their entire line, are most certainly the most gun for the least money, in my opinion and I have several in all different calibers. But for a match gun you may need a step up if you can afford it.
