CZ455 — Bedding is it Worth It?

| May 13, 2018 | 3 Comments

Shooting 22LR is one of my all time favorite things to do. Over the years I have a number of 22’s that end up joining me on just about every range visit. My family enjoy’s the 22LR just as much as I do, every year during the summer we will have a family friendly competition on who is the best 22LR marksman/woman in the family.

A few years back I acquired a CZ455 Varmint and it quickly climbed the ladder and is in the top 3 of my 22LR favorites.

Wanting to squeeze the most accuracy out of the rifle as I could after 400 rounds I started looking into bedding the rifle. It’s not that the rifle wasn’t accurate I was just looking for more, pushing the envelope. One of the things that kept it from becoming my favorite is that it was not threaded. This is an easy fix there are a few barrel manufacturers out there that produced threaded barrels and more than likely these after market barrels would improve upon the accuracy, not to mention a barrel swap on a CZ455 is very easy to do. The ability to kill two birds with one stone push the envelope of accuracy and a threaded barrel was very attractive but this is not the most cost effective. One of the barrel manufactures charge more just for the threaded barrel than I paid for the rifle. A more cost effective alternative is to just order a threaded barrel directly from CZ. But I did not chose this route either, when I started to tally up the cost of acraglas, having a local smith thread, recrown the barrel and trigger spring swap that totaled only $35 dollars more than a factory threaded barrel by itself I decided to go that route. The driving factor for me was the recrowning of the factory barrel. When discussing this alternative method with a friend of mine he essentially said look get a quality barrel that’s what makes it shoot, I believe his words were if you want accuracy you can’t be cheap. There was a lot of debate about bedding a 22 as well his thought was no bedding is needed with a quality barrel with a 22LR, he thought it was a waist of time. Being stubborn I decided to do the exact opposite and started this journey of bedding the CZ455 and having the barrel work and trigger done.

Here is the CZ455 in it’s original state and 50 yard group with RWS Subsonic HP Ammo. I do understand that higher quality ammo would most likely turn in better results. I also know that receiver torque settings can make a difference, this rifle is setup with 20in pounds in the front and 24in pounds in the rear. CZ’s recommendation for wood stocks is 25in pounds. I used these exact settings after the bedding as well. The trigger went from 4pounds down to 1.5.

I would like to caution every newbie out there to bedding much like myself to not start out bedding a CZ455. The stock is missing wood in the front and rear of the pillars which makes it a bit more challenging to deal with, also use plenty of agent release.

Groups with suppressor.

Group without the suppressor.

With so many additional things done at one time other than just the bedding it makes it difficult to answer the question is bedding a 22LR worth it, but it is definitely easier on my wallet getting it all done at once and makes this rifle my own. I am completely happy with the results of how this came out and the rifle have just went from #3 to #2 on my favorite 22LR list dethrowning my CZ 452 from the #2 slot. Though I am now thinking about doing the same work to the CZ452 after a save up some cash.

What do you think worth it or not?

    I have a CZ455 in .22 WMR and bedded it, but it still didn’t shoot as well as I’d have liked, so looked at the firing pin strikes and noted that the pin was hitting pretty well, but too far onto the rim fold, so took a Moto-Tool and ground the upper portion of the tip, so the pin now concentrates impact just below the rim fold.

    Pin strikes are properly aligned with the case body to better pinch the priming mixture and deeper, to better spread the flame around the rim. My .22 WMR CZ 455 is now a true 1 MOA rifle, which is very difficult to achieve with the .22 WMR.

  2. Agree consistent ignition is very important in rimfire. In my CZ’s I have added the JP extra power striker spring

    I have found this is all I have needed.

    On the trigger spring I have a Yodave kit in the 452 but decided to go with the MCARBO spring in the CZ455 trainer. It reduced the pull from 3pounds 11oz to 1pound 8oz.

    I just don’t think the quality of 22 wmr ammo is as good as the match 22LR has improved dramatically over the last few years but just not where us guys that like nice tight groups need it. I have a Ruger 77/22 with aftermarket trigger, bedded, barrel free floated, etc. It shoots well, but not like a tuned bolt 22LR ….
