22 rifle
I am not an expert, however I have a similar savage in 22 mag and I have terrible results with winchester ammo. CCI seems to hold groups very well for myself and I have noticed that you can phisically see deformations in the winchester bullet. As a tool and die maker I can assume that if I can see tha t the ammo is deformed and that each round has different deformations it is likely to have a serious affect on performance. Some of the people that I Know that shoot competion 22 rimfires purchase (high end) ammo from a fellow in nova scotia. I will look into the contact for you if you are interested?Thats all I Know, Hope it was some help?
