6.5x284 vs 6.5-06

I've got a old tang-safetied ruger 25-06 that's in real need of a new barrel. I'm wanting to build a long range PD rifle and I'm not quite sure which way to go.

With my rifle being a LA, would a 6.5x284 be better when you consider the seating depths of the high B.C. bullets?

A 6.5-06AI would have a little more horsepower, but can a person seat the bullet out where they need to be and still fit in the mag with this round?

Would anyone with experience shed some light for me.

TIA
 
I too was bitten by the 6.5 bug, just wanted a 6.5 to shoot so I could improve my LR shooting without breaking the bank or burning up a new barrel every year.
So after alot of research I came to the conclusions that if built by the same smiths, there wouldn't be any difference in the 2 accuracy wise, both cases are available in high quality brass, but the 6.5/284 holds the edge because fireforming is no longer needed since it has become legitimized.
In my search I went with neither one, I decided to have mine chambered in 6.5 Gibbs, more horsepower than either, sharp shouldered, straight bodied to improve case life, and 264 win performance with less powder and better barrel life.

There is more known about the 6.5X284 than all the other wildcats combined. It is much easier to get it to shoot than the other 6.5's. Case in point, Lapua makes brass for the 6.5X284. Dies are available off the shelf from Redding in the type S bushing die. Most good smiths have a 6.5X284 reamer already.
 
I say 6.5x55AI,.....I can get the same speeds with a bit less powder than the 6.5x284. I also have the 6.5-06AI, and whether it is a difference of barrels or what??? I have had better accuracy in the shorter case of the 6.5x55AI,...and the same would go for the 6.5x284. I just think the tube on my 6.5-06AI isn't as good as all the others,..so either way you go,...run a tight twist and something along the lines of RL22 or H4831sc under a 140gr pill.
 
The 264 win mag has a reputation as being real picky to load for. That is probably because of the original throating specs. With a shorter throat and a shallower angle it might be better. The larger head size will make any misalignment between: chamber, brass, and bolt more important.

The 284 based calibers do seem to benefit from the rebated rim. Any misalignments between: chamber, brass, and bolt are minimized by the rebated rim. Not a big difference, but a little bit.
