I am no expert on bolt action design but can testify to the material CZ 452 is made from. Clacamus Kimbers are not current. Strong actions in my opinion.Need one for R&D, testing of advanced military .22lr ammunition. Going to be pushing the limits so need a strong, safe bolt action rifle. Any thoughts on a modern rifle that fits this bill?
That's what I was thinking but just want to be safe. I've been through this too many times and somehow was able to keep my face in tact! Check this out:Vudoo on the Rem 700 pattern action would be the best I would think.
The week link in the 22 LR chain is the case, not the action. I can think of no action that is strained in the least by the 22 LR.
Which is why CZ walked away from producing 5mmRM rifles. It was too close to the maximum of what the actions were rated. They were talking about it, but I think when the pressure specs were conveyed (most back then just assumed all rimfires operated at the same Max pressure), the talks slowed down, and eventually just fizzled out.The cz’s made today that have the CIP proof markings pass a test which subjects them to 30% more pressure then the listed maximum.
RTHI liked this thread from the start.
AZ, I have a thought you might want to consider if you have not already.
I am sure not all rimfire cases are created equal. Have you considered testing for strength? I suspect some of the present Hyper velocity type rounds may be beefed up for high pressure. Stinger, Yellowjacket etc. At 1800 are you not just duplicating the Stinger round with a Sabot type bullet?
Thanks for sharing.
They are light years ahead of all but one 3 letter group on this rock, when it comes to a 22lr an eliminating 2 legged vermin.They have a sniper "MOS" that is pretty much strictly 22LR usage
Thanks for that info. Saved me research some time. I have no idea how to source cases in general. Looked several times and could find no one selling even standard primed 22lr cases. Let me know if you have a source.CCI Stinger. Hyper Velocity. Utilizes a 32 grain bullet at 1640 FPS. Has a nickel plated case that is longer than 22 LR but chambers in standard chamber with shorter bullet. High pressure so case may be just what you are looking for.
Resizing/reloading an priming 22lr dates back to the depression, very easy to do. Priming mix is on net, use the one with ground glass. Reloading dies for 22lr all over the place as well.Looked several times and could find no one selling even standard primed 22lr cases. Let me know if you have a source.
