CZ455 Bedding Worth it or Not?

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.

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 has 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 did the same, sort of. I bought a Savage, shot it, quite well actually. Then traded out the stock to a Boyds and bedded it at the same time. It shoots amazing, but was it the stock or being bedded to it?

Yes! Obviously.
 
I bought a 455 Varmint when they first came out and it shot ok, but I decided to make some improvements. First, I installed pillars and bedded it, then changed the trigger spring to bring it down to 6 ozs and installed an adjustable sear. Not satisfied with that I replaced the factory barrel with a Lilja barrel. Finally I replaced the factory stock with a BR stock and now with the only original parts being the receiver and the bolt it shoots like a dream, consistently under 3/8 of a inch.
 
Properly done, bedding is never bad for a rifle, and almost always better. Always worth it, for me. Nice shooting!
 
Worth it, and your results prove it.

One of my .22’s came from the factory glass bedded (Cooper), and it is a favorite.

Now if it would consent to reliably extract when it gets dirty.... the joys of a tight match chamber.

A tight chamber shouldn't make a difference in extraction of a bolt action rifle. I'd blame the extractor, unless the chamber is very rough.

A couple of suggestions:
1. Push a lead slug down the bore from the chamber to the crown. If the bore gets tighter at the crown, that's good. If it gets looser, at the crown, it may make sense to cut and re-crown the barrel at the tightest point near the muzzle. Recrown and don't thread the muzzle, but do an 11* target crown.

2. Where it's pretty much a range gun, consider installing a pressure point with bedding compound at the tip of the forend with about 5 lbs of uplift. Place about 3 inches of bedding material ahead of the front action screw while you're at it.

If you do these things and it's not shooting as well as you'd like, consider a new match barrel.
 
Chamber is very smooth, no burrs or machine marks to be found. Some ammunition doesn’t like to extract though unless the chamber is clean. Winchester Super X in particular. The chamber is cut so that the bullet is seated into the rifling, and I suspect that some brands of brass are not consistent enough in length and end up getting pinched in the lead/throat. Combined with the sometimes inconsistent rim on some cases and this issue pops up. But only after some carbon has built up.

I’ve never had an issue with wax lubed match ammo of any brand. For that matter CCI, Federal, Aguila (Eley Primed), Eley, Lapua, and RWS have all functioned just fine.

Winchester and Remington on the other hand, yeah not so much.

I have the same problem with my 540XR. It won't chamber some ammo and extraction is harder than my standard rifles. The chamber is very tight.
 
In spring of 2003 I shot NRA Collegiate Nationals for pistol at Ft. Benning, GA at the AMU range. Our team didn’t have enough free pistols to go around so SgtMaj Blankenship (retired) lent us 2 of his, both Anschutz made back when Anschutz made free pistols.

The chamber was so tight you had to use a dowel rod to chamber a round.
 
I have Lilja barrelled 40x with a Eley match chamber. Often times closing a bolt on Lapua ammo is a little hard. However, I can only recall one time in thousands of rounds that I had difficulty extracting a spent casing.
