I have run across a few of these. Are they any good? Other than an odd scope base are there any issues?

Pretty basic!!... cartridge is great... might be better to look for a P-V, or other Continental double??
Good Luck !!

As much as I like the Brno mod 21 and 22 of that era, and there awsome workmanship, I have to say that Brno O/U is cheesey badness..

I have a BRNO stopper,two triggers,solid rib,hell of a stout rifle,was a 458WM,now it's the 458 LOTT,shoots real accurate,easiest gun I ever loaded for with many different bullet weights.
