Well after a lot of research I finally realized I needed a CZ 452 Varmint.

I wanted another rimfire in my gun closet to keep my lonely Remington 541 HB company. I purchased the Brooks trigger kit and a pair of Low 11mm to weaver bases and the hex head action screws. I have to modify the front action screw as its too long at the moment. The Brooks kit is well worth it. It is a very simple install. After a few dry fires with the lightest spring, I felt that it was a bit too light. I installed the second lightest spring and its fantastic now. Passes all the bump tests and seems as safe as can be. I really don't know why one would shell out the money for a 453 when a simple mod like this kit is all that's required to make an already good trigger even better. The one problem I did have is trying to install a pair of Burris Signature rings onto the new weaver bases. The bases seem just a bit too wide. I was scraping metal off when I got them started and was lightly tapping them forward up the base. I had a spare set of weaver rings kicking around and installed them for now. I have it topped with a Nikon 6.5-20 X 44 Monarch UCC. I have about 20 different brands of ammo to try and then work from there. Testing ammo has always been one of my favorite parts of shooting.

My 541 has always set the accuracy standard for all of the other rimfires I have owned. I plan on pitting these two outstanding firearm specimans against each other as soon as I can. I will do my best to keep the test fair. Both rimfires will wear fixed 10x scopes. One with a Falcon Merlin and one with a SWFA Super Sniper. I'll compile my data and post my results with photos for those interested. If anyone feels there are specific details that I need to share in my results.....please....I encourage your input.
 
Found my CZ 452 shoots anything - cci standard really well, federal cheap stuff really well, dynapoints pretty good. Really such a non-issue for this rifle that I go with what works well with my Buckmark pistols and then also use it in the CZ.

I went with the Lux for the option of having open sights but in hindsight, now shoot Cooeys when want open sights so not likely to use this functionality and could have had ~8mm lower scope mount (sight 8mm higher than dovetail). The solution is of course to buy a varmint as well (hopefully wife wont read this) but think the next one is the Browning SA type IV or the Savage BTVS.

Cheers
 
very nice collection i have 2 lux's cz452 and i am so impressed, my anchutz is only remotley better, my 452's realy like federal gold medal,remington subsonic,winchester wild cat,lapua club, and fares pretty good with eley target,and remington yellow jackets. i once found sum norma rimfire ammo and it shot the best but i cant find anyone selling norma rimmy ammo

You adjusted pre-travel by installing one of the tubes. Good. You have pre-travel how you want it.

How easy was it to get it *just* how you wanted it? Was one tube exactly how you wanted? Or was one too little, the next too much, and you had to compromise and pick the one that was better?

How did you adjust post-travel?

You have the trigger pull how you would like it by swapping out a spring or two until you were in the general range, and then moved the adjuster to fine tune it. Good. You have trigger pull weight how you want it.

What if you want something lighter while you're at the bench?

The 453's trigger has an adjustment for pre-travel. You can set it to the *exact* amount that you want, with absolutely no compromise. You can't do that with the Brooks kit. There's no guarantee you'll get it exactly how you want, since you're just going by trial and error with several seperate brass tubes of various fixed thicknesses. Maybe one will be just right, maybe it won't. You'll probably have to compromise and pick one that is close enough. And there's no guarantee the soft brass won't spread over time and have its characteristics change just enough to spoil your day. That may never occur to the extent to make that happen, but it's certainly possible. The 453's adjustment will not suffer the same fate, and will stick exactly where you put it, for good. Advantage 453.

The 453's trigger has an adjustment for post-travel. You can set it to the *exact* amount that you want, with absolutely no compromise. You have no provision whatsoever to do this with the 452 trigger. It moves as far as it moves, period. Advantage 453.

The 453's trigger has an adjustment for pull weight. But so does the 452. No advantage either way....almost.

The 453's trigger also has a set function. Once set, it lets off at a much lower pull weight than the unset regular trigger does. This has several advantages. I can have a 2 lb 2oz trigger for metallic silhouette competition. I can also have a much lighter trigger for shooting from the bench. All I have to do is push the trigger forward until it clicks, and bingo, very light pull for benchrest shooting. With the 452 you could not easily do the same thing. You would at the very least have to remove the stock and adjust the pull weight adjuster. You may have to do more, such as swap springs. But with the 453 it is literally as simple as pushing forward on the trigger before shooting. Advantage 453.

*If* the trigger were the only difference between the 453 Varmint and the 452 Varmint, I would still have spent the extra money on the 453 Varmint like I did. Making the 452's trigger better with the Brooks kit does just that. But it is still a 452 trigger. The 453 trigger still has advantages over and above what the Brooks kit gives you.

And the trigger isn't the only difference. The 452 Varmint has one action screw, and one screw into a lug in the barrel. As a result the barrel cannot be completely free-floated. And something as simple as differing torque values on that barrel lug screw can ruin your day. The 453 Varmint has two action screws. No barrel lug. So the barrel can be completely free-floated, and depending on the wood you got, may have come already in that condition. This, too, makes the extra cost much easier to swallow. The better trigger and the better stock mounting design both add up to much more than the price difference, if you ask me.

Speaking of the wood you got...general chatter on the issue seems to be that the 453s seem to be coming with better wood than the 452s, generally speaking. Of course, the quality of the wood that you get with your CZ is more or less just luck of the draw, but word is that generally the 453s seem to be coming with a bit nicer wood on the whole.

At any rate, yes, the Brooks kit can do wonders for the 452 trigger. But, really, all that kit accomplishes is letting you make relatively coarse adjustment of pre-travel. You can make much finer adjustment of pre-travel on the 453 trigger, plus you also get to adjust post-travel. Plus you get two triggers in one. It's not a simple matter of Brooks kit cost versus 452/453 price difference. The Brooks kit does nothing to address the stock mount design.
