7X57 as a Target caliber.
This would depend on distance, It's a great caliber and will possibly give you very good groups. However , in the sport of target shooting a lot of times it comes down to equipment. That is the guy with the tuned action and custom barrel & stock will do well, and may be more consistant. however if you're thinking about long distance 1000 Meters there are better calibers. Take care and enjoy the shooting sport Bill ( for our high power I use a ROSS 303 Br ).
