Also back of the action screws a bit, my jw15 was shooting 3" groups. Backed them off now sub Moa.

When you change brands its generally recommended you fire 5 shots before grouping, it seems to make a difference for some reason.
If it is only tight when closing the bolt it might be the head space ( thick rim) so again a different brand of ammo may fix that.
Wm.Traynor wrote:My CZ 455 is new too but it has not been fired yet as I am in the process of bedding it. Out of the box, the whole rifle was slathered in oil even where it contacts the stock and this is very bad for accuracy. As if this was not bad enough, the bedding of the rifle is terrible. I always take a new rifle apart to examine the bedding and lubrication of the bolt. No factory rifle of mine has been perfect out of the box and this CZ is no exception.
My bolt has loosened-up considerably but it has been stripped and greased. Initially, it was as you described. There are videos on the web showing how to strip them. Be prepared to spend a lot of time on studying how it all works. I use moly grease.
There are a host of reasons why your rifle might not shoot but the above is a start. Keep in touch mate and Good Hunting

Yeah we tried a lot of the CCI subsonic ammo. It was all the same.
Are these the action screws?
Thanks, I will try this, as well as buy even more brands of ammo next time. Hopefully there are even more suggestions from others

Check all fasteners.
Check the crown for damage.
Try different ammo.
Give it 200 - 300 rounds in a session without a clean and see if it settles in.
If no other ammo shoots better, then start thinking about your scope.
Did it come with a test fire target from the factory showing how it grouped off the production line ? My 452 did, If I was unable to replicate the factory test I'd be placing it on the shop counter where I bought it and asking questions to the point of a refund if the factory grouping can't be replicated.

My girlfriend came with me and used one of the range’s rifles (CZ 452). The grouping I was getting was terrible. We are both new shooters yet her groupings were hovering around 1 inch, while mine spread around 2 inches+. When we swapped rifles, she was suddenly getting groupings over 2 inches and I went closer to the 1 inch mark. I had cleaned the rifle before going to the range and we shot over 100 rounds each from the same ammo boxes using Federal, CCI standard round and hollow point types. The shooting chart I got with the rifle was all over the place and had a 32mm spread over 5 shots btw.
Additionally, my bolt action is much harder than hers (loaded/unloaded is the same) and having cycled it over 100 times while shooting and probably 200 extra times just to try and work it in, it remains noticeable harder than the range’s CZ 452. I really have to push it down hard sometimes while she could use just her thumb on the range's CZ452. A range officer next to me sprayed my bolt with lubricant and even oiling the specific parts that seem to be causing the friction didn’t improve it.
I would love to hear some tips of what to try next time I go to the range Springvale / Eagle) before I try to contact CZ. I have some Elley Sport, Club and Match ammo that I bought for fine tuning my rifle which could be useful. After hearing so much about the CZ, for its accuracy and smooth bolt action I’m very disappointed. CZ specifically mentions their barrels don’t need a break-in although I don’t see why it should be so bad.
POD89 wrote:Hi there, just my 2 cents.
i bought my CZ 455 new 6 years ago.
I think i have put 1500 rounds though it?
still as stiff/tight in the bolt as it was when i bought it.
Let me stress that there is no excess force required to close it, but i've compared it to a friends CZ 452 and mine is way stiffer/tighter to cycle, still, after all the use and lube etc.
as far as groupings i can't help you.
maybe before you start yipping out screws and taking apart the gun, Ammo 1st then maybe swap scopes?
they are great little rifles i hope yours changes its tune for ya.

It did feel stiff, which was not what I was expecting from a smaller caliber rifle but I wasnt overly bothered by it either. In terms of grouping you may have just got a bad apple off the tree. Interested to know how you go with it because its probably the one I'll buy when my license comes through.

I'd go back to the range and shoot it some more, you need to get used to the trigger on your rifle, if the trigger has any creep that can really throw off groups. Try some SK ammo it always had good results in my rim fires.
CZ make good rifles but all rifles need work to make them fit the shooter, part of being a rifleman is getting to know your rifle and getting accuracy out of it.

The scope I get was a Athlon Neos 22 BDC. The shop fitted it and I hope they do find that either that or some other screws are not sitting right. I'm taking it there today and will try to buy at least 10 different ammo types. Yes I should stop whinging haha. It's been such a hassle getting the license and rifle and now these issues are working to dampen my entry into this fine hobby
