Love the 7 x 57. My go to load that seems to work in everything is a 139 gr Hornady SP or SST seated a few thous off the lands over 42 gr IMR 4895. This one went into the freezer thanks to the SST load sent from Ruger No. 1 RSI in 7 x 57. 'Twas a bang-flop. I've got an 1891 Argie with one of the new old stock 7 mm military barrels that were everywhere for $35. It's got a Lyman aperture and so only for morning hunts with sun coming up, not going down. Hopefully I'll get one with it next year. Argies are amazingly well machined.
