I have owned & used 243's & 7mm-o8's & can recommend both to you.
With the 243 i've shot pigs up to 350 pounds with no problems & lots of smaller game out to 300 yards or so & found it to be flat shooting & will wack most game comfortably up to about 300 pounds.It is pleasant to shoot.

The 7mm-08 is a great calibre & i'm really impressed by it,with light bullets 110-120 grains it shoots as flat as a 25-06 & have shot wild dogs,foxes rabbits & crows with them out beyond 300yards.
The 7mm-08 really shines with 130 & 140 grain bullets & i've taken many pigs up to 400 pounds with them,also 2 donkeys & one wild bull,dont know how much he weighed but he was a large animal,shot him just behind his front leg,thought I was going to be way undergunned for him but the 140 grain barnes x did the trick & I didn't need a second shot.Cant notice much difference in recoil between the 243 & the 7mm-08 either.

I like the tikka they weigh around 7 pounds & are a very accurate rifle so have a look if you can.

I've no experience with the 260 but can imagine it would perform pretty well on small to medium game,it should fall somewhere between the 243 & the 7mm-08 closer to the 7mm-08 I think.

Both are very accurate rounds

Anyhow,hope this has been of some help & good luck
