Anyone that posts a 270 Win kicks MORE than a magnum or ultra magnum must not be compairing like rifles. As said in the last post energy out the front is countered by recoil toward the back. Most magnums recoil 25-50 percent more than the standard calibers of 270 Win, 308 Win, or 30-06. Smart guys in the Club will post the actual figures. I bet the 270 Win he shot was very light and the magnums were all very heavy.
Compare 30-06 rem pump 760 to my rem 700 mountain rifle in 270, 270 is pretty steep/sharp in recoil. So many things like weight, stock configuration, barrel length ect contribute to felt recoil, however, all things being exactly equal, 270 win will be less recoil.
I own a Stevens 200 in .243 it is just as accurate w/hand loads all I use as my $1,200 Rem 700. Great no frills gun for the money cant go wrong with Savage/Stevens. As for the .308 and .270 I own both and can pull just as accurate shots with either. I love the .270 it drops White Tail, Mule Deer, Bear, Caribou, Elk and Pigs w/one well placed shot. I use my .270 99.5% of the time and I own several rifles from .17HRM to 300 Win Mag.
the freakin 270 kicks like a mule it has a very sharp recoil to it,i own 300 ultra mags,7mm ultra mags,300 win mags, i can shoot these a lot better than the 270 because it kick so freaking bad, i have owned 3 .270s none of witch i kept becouse of recoil,go with the .308
I'm an old retired nz meat hunter who has used a multitude of different calibers over 40 odd years.In my experience if you are bush stalking your kills are going to be close range and in open shooting no more than a couple of hundred on average .It is down to your skill at stalking and placement of your shot to get a clean kill rather than the calibre,otherwise you will lose your deer or pig due to injury and it will suffer a lingering death and often you wont find it unless you have a good dog.Saying that I have used a BAR 270 for many years in bush and open country with no complaints,and 308 in the field where it counts is equally as good .All this crap about loads,groups and ballistics does not count for much when you have to make one shot count to keep the bills paid and food on the table .
I am not a gunsmith, but any rifle action can have the barrel swapped for a different caliber if it fits in the parent action. The 308 Winchester is usually chambered in a shorter action because the cartridge doesn't need the full 30-06 length. Some companies save money by using one size action and just block the magazine with a filler pushing the shorter 308 length cartridge forward. They also change the bolt stop so the bolt doesn't retract the full length because it doesn't need to. If you are changing from say 270 Winchester to 30-06 the barrel just needs to be swapped out. The bolt face is indentical. Savage 110 actions look like they would be easy to barrel swap, it uses a method of barrel attachment similar to the 50 cal M2 machine gun. I bet someone will chime in that they have re-barreled one of their rifles.
