Thanks for all the input.
I'm looking over ballistics tables and trying to make a decision. :? The easy way out would be to buy two rifles: one for medium range and one for long range. That's easier than trying force one rifle to do diffent tasks.
As far as long range shooting, I don't know if I'd attempt anything over 300 yds. I'm a member of two different gun clubs, but their longest rifle ranges are only 200yds, so that's the greatest distance at which I can practice. I don't have a chronograph but I do have a laser rangefinder, so I am able to tell how high a particular load is shooting at an exact distance, so I can extrapolate how it will perform at a different distance.
