A good small caliber double will shoot accurately in that range. Most likely you will have a scope to aid with sight definition.

Regulation is often misunderstood. It is sometimes stated that a DR is regulated for a specific distance. This implies that the two barrels converge to a single point at the stated distance, and that they then cross and diverge at greater distances. Although a DR might be regulated this way, I don't consider it to be proper regulation. In my opinion the proper regulation is that load which causes the barrels to shoot parallel. There you will see the two barrel groups separated by the distance between the centers of the bores (a negligible amount in terms of hunting). This separation continues uniformly down-range, with the barrel groups opening up according to the accuracy of the individual barrels and the load.

I am a strong advocate of light caliber double rifles, and I have posted on the subject on this forum at various occasions.

I personally killed a whitetail standing across a harvested cornfield at 265 yards with one shot from my .300 Mag. DR a couple seasons ago. The bullet was right to the heart, as I knew it would be. The shot was no more difficult or improbable with the DR than it would have been with a bolt gun.
