Home Forums Reloading Varmint Rifles V-Max vs. Blitzking

My "go-to" load for the .223 uses a 50 grain V-max. A friend suggested I try the Z-maxes, and I loaded up some 50 grain Z-maxes with the exact same other components and specs as my normal V-max load. Groups were about 1/4" to 3/8" larger with the Z-maxes. I am not sure, but there must be SOME difference to explain the lower price of the Z-maxes, and whatever it is, my rifle doesn't like it with that load!
