Aren't the two related (though not the same), especially long range?</div></div>
You could still get the same accuracy from cartridge with less velocity.
Example: Say a .223 rem with a 16" barrel VS a 24" barrel at 1000m. Same barrels same loads same everything except one has a 16" tube and the other a 24". Lets just say the 16" barrel will give you roughly 800fps less than the 24" which means you need to dial in more elevation at 1000 than the 24" barrel. It also means that the elements will affect the bullet more than that same bullet flying faster out of the 24". However, it doesn't necessarily mean that the 16" is any less accurate than the 24". If there were a 1000m INDOOR range with NO wind or elements and you could dial in the elevation at 1000m for both guns. I'm sure the group size would be the same.
Well, thats the way I look at it. Could be wrong though. </div></div>
Close but you have over stepped it just a little, back to 600 yards the accuracy would be just as good if they were both made with match grade components but at 1000 yards the 16" barrel round will be going tran sonic making the projectiles effected by enviromental factors out of the shooters and rifles controll at 800 yards they will likley still work well but a 24" at 1000 is on the edge you would realy have to push the pressure to make a 16" 23 to stay above the transonic levels but in the rest of your asumptions you are on the money.
This is like a 16" 338 it would lack the velocity and a long barreled 300 win mag would likley overtake it because you can boost the velocity even though the BC is less but in a vacume at 300 yards the accuracy of a rifle will not be determined by barrel length within reason.
