The ancient 8X57 will indeed work, and quite well. I still have my very first deer rifle, a '44 BCD 98K. Not stock per say, has a Bishop stock and a Redfield peep sight, original barrel and front sight. I taken many deer with this rifle, in the Northern MN woods. Not really a long range rig, but I bet I could do quite well against zombies... The 308 is a great round, but all things equal the 8X57 does most anything the 308 will expect that dang fits in a short action... Why that is such a big deal I have no idea.
