Hi Miles
and welcome to the site it is nice to see young blood coming into the sport and thats coming from a middle aged one ...................don't seem that long ago when I was a young blood.

What you will eventually gather is that there is a tremendous enthusiasm amongst SERIOUS stalkers of high reputation, for the 6.5x55 Swede.
I was some what hesitant about responding to this post as you have had some good replies and also I don’t know if I am a serious stalker but in my area we have two of the most respected deer stalkers in the Scotland one of them renowned for his roe and lesser extent Sika and the other for his west coast Red deerstalking, and neither of them use a 6.5X55, the female stalker Jan Andrews uses one I believe. Still you can read the pros or cons of that calibre else were on here and make your own mind up.
So seeing that you have a bit of time to think things over I will give you my input.
Personally I have found that the only deer legal calibre that I have shot and been able to see the deer’s reaction to the shot is .243 with 100gn bullet max’. That is without a moderator fitted.
On most factory rifle stocks the comb is too low for any scope above 42mm objective lens in low mounts so if you have a scope fitted in medium or high mounts you will loose cheek weld with the stock, this leads to you having to hold you cheek slightly off the comb to see your recticle, when the rifle is fired it recoils back and up and in doing so you loose your sight picture.
So first and fore most the rifle has to fit you properly, you can get pads to fit to your rifle stock to raise the comb on the stock, some are leather and these don’t look to bad on a wooden stocks you can also get dense foam ones that have a sticky backing that work well on synthetic stocks. You can buy after market custom stocks with adjustable combs and butt plates but these are mostly built around a target style.
It amazes me that while most shooters know how important it is to have a shotgun fit you correctly they spend so little time considering how well there rifles fit.
There were some pretty horrible synthetic stocks when it comes to absorbing recoil, the early Ruger M77 come to mind, but a modern Kevlar stock from a custom manufactory will absorb recoil better than a wooden stock, all other aspects being equal.
Moving on to the cartridge
First ,one of the laws of physics:- for every reaction there is a equal and opposite reaction.
So you want most energy put into your deer for as little energy being absorbed by your shoulder.
There fore you want the most efficient cartridge or for each grain of power burnt, you want the most ftlbs of energy in your bullet.
The relationship between amount of powder burnt and velocity of the bullet is not linear. For example a .308 uses about 45 gn maximum of powder and a 30-06 uses about 60gn maximum of powder, so the 30-06 has %33 more powder than a .308 but with a 150gn bullet it will only push it %10 quicker, and if you upped the powder charge by another %33 you would be lucky to see another %5 increase in velocity.
So which cartridge gives you the most energy for you gn of powder, well some Americans kindly did a lot of research and they reached the conclusion that the most efficient medium game cartridge was the ……………………………… 7X57 Ackley Improved.
This should not be such a big surprise as the British military did a lot of work in looking into the replacement for the .303 and came to almost the same conclusion however, the yanks wanted the 7.62X51mm (.308) so that’s was that for NATO and for us of cause (the French stuck two fingers up to the yanks and went there own way and kept the 7.5X54).
There is one problem with picking this “ideal” cartridge or any other wild cat or out of the usual round, when you are in the back of nowhere and you run out of ammo’ the local sporting shop will probably only have these for deer .243,.308,.270,and 30-06.
Fine if you can take enough of you metric rounds with you but if you run out you could be up sh1t creek with out a bullet.
Don’t put too much store in the fact that a particular calibre has a large choice of bullets weights, because of the rifle twist in your barrel will only be able to stabilise a small range of these bullets, it will not for example be able to accurately shoot 100gn to 220gn bullets.
