I have used Winchester Power Points for many decades in my CZ452 Varmint, but in recent years, quality has deteriorated and I've had three misfires in one box of fifty! All fired when rotated 180 degrees in the chamber. CCI Mini Mag or Velocitor is very good, reliable ammo for hunting. For target work, I use both CCI Standards [cheap] for informal metallic silhouette shooting out to 100m, then I'm using SK Standard+ [twice the price] for more serious accuracy [I'm shooting out to 300 yards on metallic silhouettes]. One thing you might want to look at is putting a stock ammo pack on your rifle, because cheek-weld may be poor with your set up. Your scope mounts are quite high, and you may find the stock doesn't naturally align your eye with the scope as a result. The simple solution is to add a stock ammo pack. If your trigger is stock standard, various options exist to improve it. A light, crisp trigger is a real aide to better accuracy. Enjoy your rifle!

My first rifle and she’s a beauty
Just need to do something about the factory trigger as she feels heavy and long creep before breaking ... any recommendations? Timney? https://timneytriggers.com/cz-452-trigger/ .. what pull weight do u guys look for?
Edit: I read this on the Timney viewtopic.php?f=13&t=2959#p186058 - might be too tricky for a novice
I’m also using G96 on the bolt to try and loosen her up a bit - do u guys use anything else? Or spray it on a particular part of the bolt?
I think later on I’d like to swap the rings for something that looks more traditional .. these look a little “tactikool” but they seem to be doing a fine job
Had a great morning shooting her and zeroing in the scope - being a novice and with the trigger, I was getting 20 cent groups with CCI Standard, SK Rifle Match and RWS Rifle Match (all the ammo I brought along ) - but definitely more consistent with the SK and RWS
hope ur having fun with yours GN
Actually .. another question .. I had a couple of the CCI cartridges not eject after firing and stuck in the barrel .. i could pick it out easily enough but any thoughts on this would be appreciated

Will also get a few varieties of SK .22 ammo to see what all the fuss is about!
Never used it before. Range report soon.
Diamond Jim wrote:Regarding trigger, a popular trigger kit when I bought my CZ452 varmint was something called the "Yo-Dave" kit - I think from a fellow in Canada. It was about $18 for 4 springs and 4 tubular shims. I bought it online and within a hour or so trying different combinations I had a trigger pull of a little over 1kg and zero creep. The latter is important because people who try my rifle always comment that it is a "hair trigger" - it isn't. They are just not used to having no gritty, long take-up. I can lift a 1.25L bottle full of water without the trigger releasing and I can pound the butt with a rubber mallet without it letting go.
If you keep the original spring you can restore to factory standard issue any time with a few minutes work.
I'm not sure if they are still available but if it is legal for you to work on your own rifle and you have basic handyman skills I highly recommend if you can find one.
rookie wrote:Appreciate that great info flyer! That close up really shows how the mechanics of the ejectors work, many thanks.
The ejectors on my cz 452 look crisp so the jams must have been the nut behind the trigger
.. I think I was being a little reserved with the rifle early on and am now finding a confident cycle of the bolt is the best way to avoid the issue.
Good luck with yours GN. I got the tri-MOA reticle in the Leupold but am sure with the clarity they’ll all do the job
Hope the SK Rifle Match works well - they’re a greasy round (as are the RWS Rifle Match) so not sure if that’s something to look for in rounds that the CZ will shoot well.
One of the range officers said European rifles like European rounds (SK and RWS both originally from Germany?). Not sure if there’s any truth in that as CCI Standard (American) also shot well and I assume different types of ammo from the same manufacturer will shoot differently anyway.
I’m curious to try some ELEY (British?) and maybe Tikka/Sako (Finnish) soon
rookie wrote:Thanks Flyer, I went to the range again today and again experienced extraction issues with CCI Standard. The range officer said exactly the same as you and we were shining light down the chamber to see if there was debris stopping the claws from getting in far enough. Talked about getting a bore snake as an option when the rifle starts doing things like this, etc.
The guy next to me, who was a bench shooter, also said CCI was a particularly dirty round. That it could be the different lubricants used by the different rounds compounding each other. Hence the bore snake and cleaning before trying new ammo (with the understanding that you might have to shoot 20-40 rounds before they start shooting consistent with the new ammo after cleaning). Maybe that the different rounds used have different rim tolerances or could also be their “head space”, etc.
At the end of the day, the new ammo I tried today: Federal Champion seemed more consistent than the CCI Standard and ELEY Sport was awesome. I’m going to have to try a couple others of ELEY but glad the cheapest (sport) went well. RWS Rifle Match also didn’t have extraction issues.
I’ve got about 150 of the CCI Standard left and I won’t get any more of these and I’ll see if it avoids extraction issues in future.
