I shot 2 groups with it after I sighted it in. Both were about 3/4". I didn't do any load development or bullet seating depth changes. I loaded 30+ more rounds with 120gr Hornady Vmax's (the amount I had left from a bag of 50 rounds of brass) with the same load and went and shot rock chucks and squirrels with it. Then I put it in the safe about 3 years ago and it's been there ever since. Since I have several bigger 7mm's already I don't really need the gun and would rather build something bigger.
I have about 30 custom rifles
and don't shoot most of them near enough but I like to tinker with stuff (like this 7SAUM). I tinkered with it briefly and got bored so it's up for sale.
To answer your question no I wouldn't take 800 shipped for it. No offense implied but the gun is worth at least that in parts.
