I shoot about 1000-1500 centerfire rounds/year. My shooting for load development is done at 200 yards. Most of my long range practice is done at 500 yards at a range close to my house. I have limited access to 1000 yards, but it's not very convenient. I shoot 500-1000 yards a few weeks a year combined with my hunting out west. The 500 yard practice seems to pay off and enable fairly straight forward extrapolation with good success out to 1000 yards when I shoot and hunt out west.
