Just shot my Sig SSG 3000 for the first time today and have to say I am quite impressed! This is the first bolt action rifle I've purchased and I got the 24" version from Palmetto (they still have them for $1399). I went with this after debating getting a Rem 700 or Savage and putting it in a chassis and then reading some of the early reviews of the SSG 3000 and this thread too.
The setup today was the Sig SSG 3000 with a Bushnell 6200ET 4.5-30x50mm scope, Harris bipod and rear sand bag. I shot a variety of different ammo to see what it would do. The ammo was: Lake City 147gr bulk ammo (2012 headstamp), American Eagle 168gr OTM, Norma 168gr (the military overrun stuff Midway had a month of so ago) and Federal Gold Medal Match 175gr.
After sighting in the rifle at 50yds with the Lake City ammo, I took it to 100yds and shot 3rd groups with all the ammo. Best 2 groups of the day went to the AE 168gr OTM. The best group came in at 0.375". That's the smallest group I've ever shot! Had another group at 0.50" (2nd best I've ever shot) and one at 0.70" with this ammo. This ammo also seems to shoot the best in my JP LRP-07 (my best group being 0.81"), so that works out well.
3rd best group was 0.625" and that was with the Lake City 147gr bulk stuff. That was shocking as that ammo shoots very poorly in my JP and I usually just use it in my M1A to shoot at the silhouettes with iron sights. Two other groups with that ammo were were under 1" but not as good as the 0.625. Still, if I can get this ammo to regularly shoot under 1" I will be quite happy.
The Federal Gold Medal Match 175gr and the Norma 168gr shot about the same with both giving groups between 0.656" to 0.7". I'd say those two may have shot more consistently, but they didn't give the best groups. That could very easily be my shooting though...
Overall, I'm very happy with this rifle! The stock seems quite nice to me (though this thing is a tank) and the trigger is excellent too. I didn't bring my AR with a Geissele SD-Combat trigger today, but from memory I'd say they are pretty similar with the trigger on the Sig maybe being a bit nicer. Nice, smooth take up in 1st stage and then a very crisp break. Can feel the recoil more than my JP LRP-07, but that makes sense and I think a different brake would help. May try to put the same type of JP brake on the Sig to see what that does.
Going to shoot it some more on Sunday with a friend who has a Rem 700 5R in an Accuracy Intl chassis and a Savage BA10 to see what he thinks of it and to also try out his rifles. I have a feeling my first bolt gun won't be my last....
