Accurizing a 22 rimfire

What rifle? My priorities would be:

1) glass bedding
2) good glass
3) find quality ammo that your gun likes
4) trigger work

Agree, as long as the platform has the potential to meet the requirements. What level of precision and at what distance ?
 
From my reading, the best investment in .22lr accuracy, after glass/epoxy bedding is having the barrel set-back and given a proper match chamber.
(providing that the crown doesn't need attention).

The CZ 452 varmint is already a good rifle for an off the shelf rifle. You may want to try various types and grades of ammunition to see what flavour the rifle likes. What level of precision are you looking for?
 
If the barrel screw were not to be used would I want to add a screw to the action or find some other way to support the action
My rifle is very accurate I picked it up second hand and has already been bedded, brooks trigger kit installed, I have tried several different premium brands of ammo and am now setting one up for a friend. Just wondering what other tricks are out there
Thanks for input

You may want to check the CZ forum on RimfireCentral about the use and placement of a 2nd bedding screw. If your rifle is already accurate you may have done as much as can be done short of rebarreling with a match grade barrel and changing to a synthetic stock. It depends on the level of precision you are expecting ?!

:agree: Dryfire has given you excellent advice.
 
Thanks for the advice guys. Although the rifle is already quite accurate is there such a thing as being too accurate or accurate enough? Who has the best synthetic stocks for cz 452 varmint and I'm thinking hard about taking the barrel mounting screw off and trying it that way to see if it makes a difference

That rifle should have come from the factory with all the accuracy built into it.
Don't undo a hundred years of their experience, by playing wth the bedding.
The trigger may be too heavy, you know, lawyers adjustment instead of a rifleman's settings. However, I think that trigger can be lightened with no other adjustment than replacing the present trigger spring with a lighter one. Otherwise, don't do anything with the trigger.
I am not belittleing your shooting, but I will bet right now that the rifle has more accuracy built into it than you (or I) have in us!
Concentrate on the right amunition for it.
 
I might have to back track a bit on the CZ trigger.
I have two forerunners of the CZ, the Brno Model one and the Brno Model 5. I thought the CZ had the same trigger as the #5, but they are not the same.
There is a big difference in the triggers between the #1 and the #5. The #1 has a shorter compression spring, making it harder to get just right, and the trigger has two way adjustments for creep and over run. A bit critical to adjust, but ends up as an excellent trigger.
The #5 has a long compression spring which is easier to get what is wanted, by changing springs to get the right tension. It then becomes a first rate trigger.
But I find out the CZ trigger is different again and I am not familiar with it.

Not sure which trigger you were looking at, but the Brno model 5 trigger is exactly the same as the 452 trigger.

Not sure which model CZ I am talking about either, but an owner got a kit for his trigger, which included some type of shims for adjustment.
That is what I was thinking of, and as I said, I'm not familiar with the CZ trigger.
My last post was just to make it clear that I am not familiar with the CZ trigger and my first post may have been misleading in that respect.
If the CZ has the same trigger as the Model 5, they have a great trigger.
 
The brass tubing shims for the CZ trigger kit work on the Brno model 5, too. I've put in a handful of those kits for people in CZ 452 rifles, and also put one in my 1957 Brno Model 5. They're the same. :) But CZ 453 triggers are entirely different, and also don't require a kit as they have adjustments for everything. I haven't seen a CZ 455 yet, so I don't know if they retained the 452-style trigger or not. I haven't done any reading on the 455 yet, either, but I imagine the trigger info is out there, as quite a few people have picked up a 455.
