They may well be harder to find than AYAs in Ukraine!

However,used with the right ammunition (and 2 1/2" shells are ample for all game shooting)they have no more limitations than a modern foreign version.

In fact, they are better made and less liable to shoot loose in my experience.

The point about ammunition is a good one - if availability is an issue in Ukraine - if only 70mm shells are available, be sure to buy a gun chambered for them.
