I took the old - and when I say old, I mean built in 1943 - K31 to the range last weekend, and after some heavy scope adjustments, sighted her in at 100 yards with a 1" 3-shot group to finish it off... I think next year, I'm going to pick the M91/30 - also 1943 - and take her out to play with iron sights only... But more than likely, I'll just take the scope off the K31 and shoot that, because it's a tack driver out to 600 yards.
On a side note, great to be back. =)
