That looks like an excellent string with only 11 fps spread.Good shooting also. Shooting in the wind is tough.Shooting off front and rear bags instead of the bi-pod might help the long range groups some.Jim - jhm757
try some eunjin 43.3 gr in that wind, also does good with 26 gr predator red tips] but by far in the wind the eunjins worked well in mine,but mine is tuned,
