Ok so now I have my new leftie CZ452 what should I do about the trigger? Not that it is shabby or anything but what are the choices? I see on another chat the mention of a Brooks kit for it and wonder what I can expect from this. Also what other options are there for this rifle or does it really need any? Not like it shoots poorly or anything. Amazing accuracy even after only 100 rounds of mixed origin. Curious.

The trigger
on my 452, I took up the creep using the aluminium tape trick around the center pin. Put a few wraps until I could not feel anymore creep. I polished the contact surfaces between the sear and the trigger and was able to get a softer spring that worked for me. Last I checked my trigger was at 10oz. It has not failed me once. It is just the way I like it, light.
The triggers on my bench guns are Jewells set at 2oz and about 6oz. The 10 oz on the CZ is about as high as I would go on the bench. This is one time when I prefer them soft.
I have since ordered a adjustable sear from Brownells. It should be in next week. That will take the place of the aluminium tape.
The other thing I did was removed the bolt that is attached to the barrel and pillar bedded the action to the stock. I left the barrel totally free floated. With the bedding and the single screw there is no movement at all. Does it shoot. Most accurate rimfire I have ever had. Shoots circles around my done up Click Clack.

Yes if you are going to be shooting benchrest as you mentioned 10oz is a bit heavy - especially if you are going to be shooting free recoil. On my brno #4 (appears to be the same trigger mechanism?) I replaced the spring (or maybe just took it right out) polished the sear, etc and it is around 7oz. Still a tad heavey for bench rest but it works.
The brooks kit won't help you much now...

Well, I plan to shoot bench as well as hunt with it so 10oz might be a tad light. Floating the stock is a good plan too. I have only had it to the range once so far and put about 100 rounds thru it. Quite a bit different feel than the 1022-much more refined. Are these mods specific to benchrest or will I benefit overall? Really necessary or just a good idea? Feels pretty good so far but then that is after shooting a 1022 for quite a while.

Ok, if you are going to be hunting as well 10oz would be too light. Probably around 2lbs would be just about perfect. The brooks kit has different springs that will allow you to lower the trigger to different pull weights. I have heard of some people not recieving the items they have bought from Eric (brooks) though 
. All of these mods will help with accuracy a bit but - it really just depends on how accurate you need/want it to be. Glass bedding and pillar bedding take a bit of time - and maybe are a bit risky for first try but the will help with accuracy - maybe not a whole lot but "enough"

asked about bedding the CZ. There was nothing special about bedding it. I did make sure that I had ample clearance around the barrel from muzzle end to the front of the receiver. I then relieved the wood where the receiver touches it all around.
This is a B4 picture. I drilled the hole where the bolt fits thru slightly larger to accept a steel pillar that would bottom out as close as possible to the reciever. I relieved the wood along the sides with a deep socket and 100 grit. I used a Dremel tool to remove and roughen up the tang area. If you look at the picture it is milled out flat and the receiver is round. If anything bedding the tang would definately be beneficial in supporting the tang area.
I prefit the barreled action into the relieved stock and put tape around the barrel near the front of the stock till it sat the way I wanted it buy using a level.
I removed the trigger by knocking out the front and rear pins. Filled all holes with putty. Painted it with a few coates of the liquid furniture wax that I use for bedding. I also removed the dovetail attachment from the barrel.
I should note that I kept the bottom metal in place when I bedded it so the pillar would bottom out against it.
Mixed the Marine Tex and installed the pillar then painted the stock with the compound. Set the barreled action in place and lightly threaded the bolt into the reciver to make sure it was centered. Let cure.
Sitting curing
After initial bedding. Did not have enough compound in the corners of the tang and forgot to do the front part of the receiver.
After second bedding and B4 final cleanup. The thing with bedding the CZ is the compund around the pillar. Fill it in really good. After it cures you will have to remove quite a bit of it on the trigger side and the magazine side of teh pillar or everything will not fit. Just use the sanding drum on your Dremel. This is what it should look like when all is said and done.
You can see where I removed the bedding compound from either side of the pillar.
I cannot see any movement at all of the barreled action in the stock when I try and twist things. I do not use the bolt that is attahced to the dovetail in the barrel. I removed it and am running with just one bolt. As I said I see no movement at all.

Nice job on the bedding.
That front pillar is actually a barrel tuner. Can really help your gun shoot. Will help with sorting through all the different ammos too.
However, don't expect to turn Wally bulk to Eley Tenex. It will make Wally special bette though.
rimfirecentral.com has lots of info on this rifle. There are adj bit and pieces to get the trigger under 1lbs.
I fully expect that you can shoot 1" or better at 100yds under calm conditions with the right match ammo.

Excellent instructions and photos, thank you. (like the jig too).
I think I understand the pillar is really a sleeve for the bolt that tightens against metal plate under stock and receiver so holds action against stock without really compressing stock. Am tempted to try this, just a little afraid.
Cheers

I am still in the process of trying different ammos but I am heading to better ammo anyways. I have a brick of CCI Minimag hp and some Velociter but have a mix of Winchester and Remmie ammo too to play with from testing the 1022. Already finding nice groups at 50m with the CCI and still tweeking the scope yet. After the 1022 I do not find the trigger all that bad but will look at it closer next time. Anyone in Canada carry the trigger kits mentioned? Also no mention of "pillar" in the parts list. Is it a bolt or sleeve? Google only refers to columns. Yeah,copy that on the pics and the jig. Sweet. Aside from that-my trigger is adjustable for pressure and creep. Any trick to the adjust or just try and see?

I purchased an adjustable trigger from Brownels and wouldn't even consider having another 452 without it. It took that hard crappy trigger on my 452 style and made it the most fun to shoot .22 I own. I now just got a laminate stock for it from Richards microfit, to replace that plastic piece of crap, and am going to start the fit and finish job on it soon.
No, it's just a mount.

Allows you to apply varying amounts of tension on the barrel. This can affect the barrel tuning thus the accuracy of any ammo going through it.
A pretty crude set up. Try it.

Have you tried tightening and loosening that bolt while shooting?
On my Bruno #4, it certainly had an effect on how the ammo shot but it was about midway on the barrel length.

The fact that it exhibits certain traits doesn't change the fact that it is simply a mount. It is not a barrel tuner. Tightening and loosening the other screw in the action will also have an affect on accuracy. Does that mean it is an action tuner?
