No, the Saiga will only give 3 shot groups of 1" with handloads taylored to it. It does shoot 2" groups (again, 3-shot) with good quality fmj milsurp ammo though which really pleased me when I first discoved this. That's with optics installed (4x scope). I can count on it to give 1.5 - 2" groups with 150 grain soft points.
I wasn't suggesting that it's of equal quality to the Sauer - no way, just that for pig hunting, it'll do the job just as well and maybe even better if you're out to drop as many as you can find.
Part of it's performance has to do with the Power Custom fire control group that I dropped into it - it's their 308 Veper model and is fully adjustable. I have it adjusted to single stage mode and fairly light - breaks very cleanly.
The stock Saiga's trigger is a nightmare.
Here's a picture of it sans optics and with a 20 round aftermarket mag:
Notice that this is a 16" barreled version - and the barrel is rather beefy. That too contributes to the accuracy I think.
