I would have a difficult time giving up the 452 for the 527.
What other rifles do you have? Do you hunt?
I don't hunt. I want to learn but there are hoooooops to jump through in order to get a licence. I still hope to get there, but I have been saying that for more years than I care to admit (hangs head in shame).
My other rifles are a VZ58 ex-military rifle reconditioned as a semi for the civilian market, meaning x39 calibre cross-over, my 452 (22LR) and a CZ 550 Varmint in .308.
The VZ is for competitions. The 452 for training, plinking. The 550 is a would-be hunting rifle and longer range target practice when I go practice with some of the "National Guard" guys.
I wouldn't want to use sell any of them, TBH, but the one that is probably closest to what the 527 would be is that 452.
7.62x39 is not that much more expensive than 22LR here.
About €180-200 for 1000 .22 and about €250 for 1000 Barnaul steel-cased x39.
And I can reload for 7.62x39, although not at a lower price per cartridge, only higher quality.
So both work as a training aid.
Both work as that handy survival option.
Both have small cartridges for storage (but 22 wins by some margin)
Both would be a 10-rounder bolt gun, with suppressors as an option.
The only other guns, I could otherwise sell are the single shot 16g Beretta and 12g VC Franchi semi auto that I very rarely use, but these were my grandfather's and the thought of selling them doesn't sit well, despite being a viable option on the logic-front. I have too much use for my pistols to consider ditching those.
