6.5x47 vs 6.5x55

I'm in the process of building a 47 with a 20 inch barrel.
Dies,brass,bullits,and tools are easy to find.
And from my research,it'll take any animal in Canada. Well maybe not a Grizzly:)

As Jerry mentioned, all things being equal (pressure) the 6.5x55 does give you an extra 200 fps. However, all the reloading data I reviewed shows the recommended pressure for the 6.5x55 is lower therefore bullet speed between the 2 is virtually identically. My understanding is that the main benefit of the 6.5x47 is you can do everything that a 6.5x55 can do with a short action rifle. Whereas to seat the long 6.5 bullets out of the powder column in the 6.5x55 you need a long action (30-06 length). Jerry can you confirm?

If you go by the "optimum" lengths using the longer 140 class bullets, the 6.5X47L is "short", the 6.5 Creedmoor is "ideal", the 260 is "long" for a standard 2.85" mag.

The 6.5 Swede is really an intermediate action length cartridge... ie Tikka T3 and M96, but it can work in a "long" SA or a "short" LA.

With varying lengths of mags and bullet weights, this can change as suited. There is no one answer as you can modify things all over the place to fit... or not.

The rules of thumb that do stay... burn more powder, at the same pressure, in the same effective bore length, bullet will go faster.

As always, figure out the tasks, the parts will be easy ...

I would just pick whatever turns you on, they're all going to do what your asking.
Punching paper and a hunt ,here and there.
260,47,CM,55, I don't think you'll notice the diff, I'm sure the animal won't.

I was in your situation a few months ago,after all the research,advice from here, I decided on the .47 with a Short CFW barrel.
It'll do what I want it for. Which is pretty much the same as you. Well except for the 1000 yard part. I'm aiming for 500 ... figure that should take awhile:)

Getting the straight goods on the 6.5x55 loading is difficult due to the older military guns that have been chambered in the cartridge, and are not up to modern day pressures of 60,000 to 62,000 psi. If you buy a new modern day gun like the Savage or Remington 700 chambered in the Swede they will be quite suitable for the pressure. This link gives some reasonable loads to modern pressures. Should be able to get a 140 grain up to the 2900 fps range depending on your barrel length.
 
Wen I was a kid I know a trapper that would take me out trapping one trip we went hunting wolfs he sade the 6.5x55 was perfect for wolfs and it was all he would use
 
Figure out what you want, the rest is easy.

I wanted a Tikka CTR, Lapua brass, only option was 260Rem. Very happy with it. TRG mags are 2.95" long, can seat 139gr scenars to the max.
My SRS mags are also 2.95".
 
Another issue with the 6.5X55SE(proper designation), is that European cases heads are a little wider at .480" as compared to the USA version at .473". The 6.5X47 Lapua (.473" case head)is much more popular in all types of target rifle competitions starting with 300m ISU and no 6.5X55SE and can be used in Rem 700-style SA whereas the 6.5X55SE needs a longer action.

The Scenar 139 is 1.364" long. When this bullet is seated with the base at the neck shoulder junction the COAL will be 3.140" long. A Hornady ELD-X is 1.440" long. COAL seated the same is 3.216". A Berger 140 will be nearly the same...
