Well, I've made no progress in selecting a scope mount for it, but I did take the MS to the range today. I started with a hyper-technical selection of cartridges -- the cheapest .270s Cabela's sells (Federal 150 gr which seems to be heavy for caliber).

Here are a are a few observations:

(1) the excessively carved stock, which is discordant to my eye, is actually a good fit for me, and, it turns out, that the white spacers don't really detract from accuracy;

(2) I got 2 inch groups from a bench rest, centered about 2 inches high at 100 yards -- I expect to shrink that group by 50% with a scope (65 year old eyes) -- and 3 inch groups at 50 yards shooting off hand;

(3) the double set trigger is a hoot -- I haven't used one of these in 20 years and I've never hunted with one (what are your experiences hunting with them?).

Anyway, it's a shooter and a keeper. I will have to put a scope on it; I've got no chance of picking up the iron sights in poor light.
