Would it be legal to use a CP muzzle break in a open F class match if it was in the closed position? I`de be one sure buyer it it is! Does anyone know if you could use one?
Probably not an issue with a 1000 yard rifle, when time of flight is about 1.5 seconds or longer. Even at 600 yards, time of flight is around .8 seconds, which may be long enough. Using a seperate spotting scope, it's possible to move from rifle to spotting scope in less than .8 seconds.Shelley said:Being able to see when and where the bullet hits the berm is a very valuable sighting aid.
