Either of these rifles are good and well regarded for their segment. Your Vepr should shoot well.
Here's a review of a 7.62x54R version:
It's sad that some folks still make blanket statements about how any Eastern Block rifle are not accurate, poorly constructed firearms out there and haven't owned or shot one.
Wasn't double/triple tap a solution to the poor stopping power of the 5.56 rounds? Is double/triple tap necessary for well placed .308 rounds? Either way, don't get caught up in the caliber wars. Your .308 Vepr will serve you well.
