I have a 16" barrel Creedmoor that has hit steel @850yds.( Verry windy day)
I can regularly hit steel at 450 yds.
250-300 yds is a chip shot for that gun.
There is commercial ammo that that gun likes and others it doesn't shoot near as well.
For a hunting gun your not going to miss the extra 2" of weight or the slight decrease in muzzle velocity.
