Well I decided it was about time that I bought myself a bolt action 22. I never had one from new or a 22 that shot as well as I would have liked. I was looking for something easily affordable and would shoot good out of the box with just minor improvements. Alas the CZ 452 Varmint.

First things first. B4 I headed out to the range was to give it a good cleaning. Next was to get the trigger pull down to something I was very happy with. Tough act to follow for someone who uses Jewell triggers on whatever they can put them on. I actually was able to safely get it down to 1-1.1 lbs with a very crisp break. The only cost was 28cents for a roll pin to replace the center staked pin of the trigger asssembly. I had a spring that worked for the trigger. The creep was taken up by the use of aluminium tape. I put about 4 wraps of it on the center pin. I also polished the areas of contact with my Dremel tool to help smooth it out. I now have a trigger that I can live with.

Next I made sure there was no wood touching the barrel. I removed what needed to be removed then resealed the raw wood with tru oil.

Now I was ready to head to the range.

First thoughts on the CZ 22 was this is a keeper. Out of the box it shoots great. Here are a couple of the targets I shot yesterday at 25 yards. I have not really shot it at 50 as the winds just never seem to drop down a whole lot this weekend. The few groups I did shoot definately shoot better than my 10/22 with the Green Mtn barrel at 50. I just cannot get it to shoot at 50. It will keep them in a 1/2" or less.

The ammo that I have shot is just Lapua Standard Club and Eley Target. This the best ammo I have access to.

Here are the targets. The first target is as follows. The 3 target bulls on the left was fired kwith a clean bore with Win T22. Starting at the bottom and going up. Switched to the Eley for the middle top to bottom and the far right 3 bulls bottom up. The second target was Eley as well on all 5 bulls. Groups were 5 shot groups. I think not bad.

Future improvements will be a BR stock for it. I really feel that is where my groups open up. If I had the flat forend it would be more consistent.

In the meantime I plan on pillar bedding the action screw. I also plan on eliminating the recoil lug and bolt that attaches to the barrel and replacing it by drilling and tapping the rear of the receiver to accept a bolt. This will be pillar bedded as well. Then the entire receiver area of the stock will receive a skim bed of Marine Tex.

I have heard comments that what if the bolt in the back srews with the groupings. I just remove it and all I have is a drilled and tapped hole in the back of the receiver. I look at it one will never know unless they try it.

Really I feel if you look at the tagets closely and were able to move the shots that just missed out of the groups it is one hummer of a gun. I really feel those misses are me and nothing but.

I got to some more

thinking this morning.

How about trying shooting it without the front recoil lug/bolt in place? I have removed it and will hopefully get out to the range to try it out sometime today. The receiver and barrel stay fairly rigid without the front bolt.

I will also take some very dense foam that I have and will try it out with a pressure point at the front of the barrel.

I am starting to like playing with the ideas.

I also had talked to Guntech about my ideas and he mentioned many years ago how they used to take older Brno's and put them into CIL Anschutz 190 target stocks. They would bed the action and the first couple inches of the barrel. He was not 100% sure if they did it without the front bolt but he thought more along the lines that it was without. He said they shot very well.

Will keep posted with my findings.

I should also mention (I hate to say it) but the scope I am using is a cheap Bushnell Banner 6-18X50mm. I should put the 36X Weaver on it but it is sitting waiting for Guntech to finish my 6PPC Benchrest gun.
 
Just curious, with your new CZ shooting so well as is, why do you want to fiddle with it?

It seems to like the way it is right now.

If it were mine I would shoot it more, at further ranges and in better conditions to see what it is capable of before tinkering.
 
Why do I want to fiddle

with it? That is easy. I want to take every variable out which may potentially effect the accuracy of the gun. You never will know it until you try it.

Really it is no different than those who are adement to have a Sako extractor installed on there Rem 700 bolts. Is it necessary? No. Is not the factory extractor good enough? Is there a possible safety concern with the modification? Yes. People still do it.

Just as I will still do the modifications to see what effect there is if any.

I did get back to the range for a while this afternoon. What I did prove was it did not like a pressure point on the front. I also believe that the gun will shoot better ( more consistently) without the recoil lug/bolt in the barrel. I just used the one bolt that is in the receiver and it shot quite well. I will post the target later. It just took some time to figure out how to hold it to get consistency from group to group. I think I figured it out.
 
I think that is pretty fair shooting.:)I hope to buy a 452 American in the very near future. I too like playing around with all the variables to strive for that perfect combo. I shot Sporting and Match 3 pos. rifle for years and there is no better feeling than putting that round into the X-ring.
 
Here are my targets from the other

day without the barrel lug/bolt in place.

I started again with a clean barrel. I fired a 5 shot fouler group with the Win T22. Then proceeded onto record targets.

What I have found out is it definately takes some time for the barrel to get enough fouling down the bore to settle it down. I figure anywhere up to around 50 roundsB4 it levels out.

I also tried different ways of holding the gun and found that it shot best with face off of the stock, slight tang area pressure with a light hold against the shoulder. It was very inconsistent free recoil. I think that is due to the standard stock configuration. If it were a Benchrest type of stock with a flat forend that would be a different story.

Anyway the groups really do not look much different without the lug than they do with. The first target was starting with the clean bore. The second target was started at round 51 and up and after I thought I had an idea of how to hold the gun. The groups got much better.

Tommorrow weather permitting I will get out and do more shooting to confirm what I think. I will not clean the bore just shoot as is. That will be round 81 fired tommorrow.

Target #1 with the bottom left bull is the best 5 shot group yet. I have had many close but that takes it. I am still very impressed with what I am seeing. Especially on how well that CHEAP Bushnell Banner 6-18 is performing. It used to be on a 22-250 and is still holding.

I currently have a cz 452 style. this is by far the best shooting .22 I've ever had. All I've done to mine so far is changed the trigger spring and bought an adjustable sear for it. What an amazing differance that adjustable sear makes. i havn't had too much of a chance to shoot it with out wind, but even in a wind storm @ 25 yards I'm shooting jagged one hole groups. now, I'm waiting for a black and grey lamanate stock for it from richards micro fit 9was supposed to be here 3 weeks ago. Then I'm going to see how it shoots with the front screw removed as well. I hope my results are as good as yours.
 
Range report from this

morning July 4.

Like stated I started shooting at shot number 81.

The first group was the first target, bull 1. Not to good. After that they did what I hoped it would. This thing will shoot and very well with Eley Target. It is not very expensive but expensive enough compared to most rimfire ammo. It would be nice to try the real expensive stuff buttttttt...............

The next and first real attempt at shooting 50 yards was on the second target. Group 1 was a screamer in my mind. Then things hit me with a reality check. Regardless of that I know it can and will shoot VERY, VERY WELL at 50 yards. The wind too was starting to pick up.

My results on this CZ are that it definately is a keeper.

The only thing that will help improve things is by putting on a more powerful scope like my Weaver 36 and a Benchrest stock. You then will definately be able to disect the bulls and have a lot more stability on the bags.

Sorry I took the pictures B4 I numbered them. Target 1 is Bull 1 from bottom right up and down the middle.

Target 2 is Bull 1 from the top left down, up the middle and down the right side.

Great shooting cybb486 :cool: :)

That one group at 50 is great! Might want to try some Lapua super club in your CZ. Moderately priced and seems to work great in all the CZ's I have shot.

I also use a Cowan windage adjustable rest and that seems to really help with consistancy.

Sorry if you mentioned htis allready but what scope do you have on the gun right now?
 
I just have a cheap

Banner 6-18x on it. I know I should put a higher power scope on it but it is not in the budget right now. I will get a Weaver 36X for it when I get a chance. I have one right now but it is delegated to my Benchrest 6PPC project.

I also am just using a cheap homemade rest on it. I do not use my good rest for the 22 as it is shaped for the wide flat forends. I do not want to put it out of shape.

So yes there are things I can do to improve it.

The first will be to bed the stock but that will wait until I have my other gun build in hand. It will take up my time shooting it so I well get the CZ bedded. I am also thinking of getting a Stith stock for it or anyone who makes one for it that does not need a lot of finishing. Putting it in a stock with that big flat forend will make a big difference.

Maybe I can take the 8.5-25 Leupy off of the 6BR when the PPC shows and put it on the CZ. It is a lot of scope but I have it.

I too toyed with my Varmint until it shot consistently. I bought a Boyd's laminate stock for mine, when they were 65 bucks US. I had to sand the channel and do a lot of bedding work as this stock is designed for the smaller barrel models. I left out the front barrel lug and am only using the one receiver screw. No problems yet, and it is consistent every time out, and shoots better than it did with the original 2x4 looking stock(the reason I changed it). They are very capable guns, but my Brno model 5 will still outshoot my CZ's.

I decided to get

at it and pillar bed the stock.

One mistake I made was forgetting to get a few pics of the stock with the wet Marine Tex B4 I put the barrel back into the stock. I will show you though pics that I did take B4 there was ever any bedding in the stock.

Initially I made the pillar. I just used a piece of steel tubing cut with a tubing cutter. It fit with a little bit of room around it to take the Marine Tex. I ground it down to length just using the drill press and a file. Finished the ends off with sandpaper. Roughed the outside and set it in Marine Tex.

Be very careful if you ever do this with the trigger still on. I got lucky and almost had to break it out. The way that the trigger works the pillar cannot be larger than the hole that is existing. I still will have to remove a portion of the pillar and the Marine Tex so the trigger will function. I will try to illustrate that in the pictures to follow.

Whether or not the pillar will be effective in this gun I am not sure. There is very little room for a pillar. If anything, it will keep the wood on the underside from compressing when the screw is tightened.

This morning I got at the skim bed of the stock to the receiver. I opened up the tang area of the stock with the dremel tool. The sides of the stock were roughed up using 100grit sandpaper wrapped around a deep socket. There is a gap between the stock and the reciever so I felt I would not have to remove much wood. The trigger was then removed and all holes filled with modeling clay. I also wrapped the barrel at the end of the stock with masking tape until I got the top line of the stock parallel with the top of the receiver. I just used a small level to get it close. Coated the receiver with a few coats of Johnson's wax along with the screw. Mixed the Marine Tex and applied it to the stock. Set the barrel in, aligned it with the screw, cleaned off the wood and receiver of the Marine Tex that squirted out and here we sit waiting. There are a few spots where I did not give quite enough so I may have to touch those up.

Here are a few pics.

Just the curing wait.

Not that it may matter but just to show that I bedded the top of the receiver in line with the line of the stock.

I also forgot to mention

that as tested and with my mods to the trigger it is at approx the 10oz mark.:D:D No creep, and crisp.:D:D Just the way I like it.

I ended up using a Fuzzy Limey's tip with the aluminium tape and a Brooks trigger spring that I got from a shooting aquaintence.

I think it is SWEET.:D:D:D
 
Well here is the job

after 8 hours of curing. That is the nice thing about Marine Tex. Whatever you mixed and was left over I use it as my guide as to whether or not it is ready to come out of the stock. I mix it on paper. When it breaks with a snap when bent I know it is hard enough.

I am getting ready to do a skim in the areas of the tang that I missed. I thought it would squeeze into those areas but I guess I did not have enough laid in. It probably will not make a difference but it bugs me seeing those voids. I am also going to fill in the area by the barrel channel.

The first pic was B4 cleanup and the second after.

I will post one more pic with the final product tommorrow.

Regardless what, I enjoy doing what I did today. Hopefully it will be all worthwhile.

What I can tell you is installing the pillar in the center screw I feel is a waste of time. I will explain in more detail tommorrow with a picture of how much I had to grind down with the Dremel tool on either side of the pillar. The trigger side so the trigger would work properly and the clip side so the clip will fit back in place.

Do you try any different cleaning procedures to see if your groups come back quicker?

With my new Savage 93R17BTVS I was getting very inconsistent groups right after cleaning. Needed between 50 and 100 rounds before I'd get back under MOA. I tried lots of different methods, different bore cleaners, different ammo, etc, but settled on a bore snake, down the bore twice, after 200 rounds.

When I get to 300 without cleaning, the groups open a little, so figured 200 would be a good place to start.

Works sweet, right after the bore snake, the rounds are unaffected. I've fired about 1200 rounds so far this way, workin great so far.

I know it's a different beast then your .22 (copper jacketed VS. lead) but figured cleaning it differently or with something different might keep ya from wasting (lol, if you can call it that) some ammo.

Just my $.02. Normally I never clean any of my guns until they stop working properly. This is the first gun I've tried to keep accuracy consistent.

Finally all complete.................

Here is the final photo of the completed bedding job. Hopefully the weather will hold out for the rest of today so I can make it to the range this evening for the test.

It will be shot without the front recoil lug/screw. It is very,very solid in the stock now. I cannot see any movement of the barreled action.
