I appreciate this one is a bit of an old chestnut but am very interested in any new views:
I've just acquired a 6.5x55 MT which is the 20'' barrel fitted with an ASE Ultra over barrel mod. I've yet to get up and running as still need to find 30mm s/s extra low rings (anyone got a set for sale??).
I understand the round is 'lobby' at the best of times, will the barrel length significantly exaggerate this compared to the full length version? I'm thinking of starting with factory Hornady SST Superformance 120gr and my idea of range is 350-400m max by the way!
Thanks in anticipation
