Thanks lads, it is 410 yards,
I love my cooper rifle, it shoots very well, i had to order a 1-9 twist barrel as a special order,
it cost slightly more but well worth it, it will shoot 75gr Amax very well,
but i have also shot barnes varmint grenades 36gr these shot .5"at 100yds
also 50 and 52gr hornady bullets shoot very well,
As for negatives all i can think of that they have "very" nice wood,
its a shame to take them out into the hunting field where they pick up scratches ect,
but they also do a phoenix stock which is better for a hunting rifle.
regards
john.
