Any issue shooting hyper velocity ammo out of CZ?

[cdncowboy]

Does anyone know if there are any issues shooting hyper velocity rounds like cci velocitor out of a CZ 455?

I use the hyper velocity CCI SHP ammo (rated at 1640FPS) out of my 452 Lux as my default ammo for varminting. Call them my little anti-gopher grenades. I get very good accuracy results out of them out past 75 yards, with a nice trajectory - 25 yard zero yields 1/2" high at 50 and 1/4" low at 75.

There are going to be a couple of people who claim the chamber is too tight, but I've put probably 4 or 5 thousand rounds through it (shoot a lot of gophers every year), without any loss of accuracy, and so far, my #### hasn't fallen off.

I have shot Stingers out of my 455 without any issues.

You’ll have to verify your point of impact from the previous ammo you are using currently.
I found it shot a couple inches higher at 25 yards over AE hollow points myself.

your fine in new modern bolt action firearms, there may be risks involved with shooting them in some of the older rifles and blow back semi autos, which if I am not mistaken is the warning written right on the end flap of the box

I shoot it out of my 452's without issue.

Much obliged for the info gents.

Supposedly the CCI Stinger case is too long to reliably chamber, but it might depend on your specific rifle.

I have had 4 cz 22lr's 2 452's and 2 455's everything chambered just fine.

Exactly. Modern firearm and your good to go shooting any 22lr ammo on the market. And I would say in a bolt/lever/pump rifle there is little concern versus a semi with a bolt being forced back with recoil.

The issue I have found with all hyper velocity ammo is that I cannot get it to group decently. Actually a cheap Marlin 80 shoots hyper best of all....go figure.
