Russian caliber ammo instantly brings to mind AKMs and SKS rifles, firearms never known for stellar accuracy. While it is true there USED to be widely available piles of surplus ammo, that ammunition wasn't exactly match grade, and while a good fit for ComBloc rifles, most didn't work exceedingly well in a bolt action rifle.
How do I know?
Because this CZ 527M is mine. caliber 7.62x39mm.
Why did I get this little carbine? Easy - I already reloaded 7.62x39mm and really liked the idea of a light and handy camp rifle that was a more accurate bolt action as well as a detachable magazine rifle. The CZ 527M fit the bill.
It worked well for me in its original guise - please note, I am NO great rifle shot.
Started experimenting with casting my own bullets for the caliber, too,
Until I got my NOE 129grain mold and some hard good lead, it didn't work extremely well, but that changed. That's a GREAT bullet!
I mentioned to a gunsmith friend of mine of my idea for a camp/scout carbine, with a spare magazine in the stock and a handy pistol grip, but something that shouldn't cause loose bowels among the week-kneed crowds of out of state tourists. He took the idea and ran with it, creating this,
Took it hunting the other day,
When we decided 112 degrees was a wee bit too warn to be wandering the desert, we did a little informal target practice on some foam plates one gent brought, and I did get this group,
I think the caliber, loaded right and with someone, (unlike me), who can shoot straight has a lot of potential. It it was renamed/rebadged to some American sounding name it would be looked at in a better light by bolt action rifle enthusiasts, but sold as it is, it will always be looked down and sneered at. That's OK, more components for me. If you don't like it, no biggie - I can't find a single use for .243, myself, but lots and lots of people love it.
The beauty of America - diversity of choice.
