Gun not accurate
I bought a 17 hmr a few months ago. It's a NEF sporter got it to carry in the truck to pop goundhogs . Well I put a 3/9 scope on it an went to sight it in an the best that it will group is around 2 inches at a hundred yrd's. Called NEF they said as long as it groups under 2 1/2 inches at 100 yrd's that's there standard. My question,is there any way to thighten up the groups or should I trade it off. A friend has the same gun an it put's them in the same hole. I already tried a different scope that didn't help.
