i was browsing an american forum when i came accross this article, it talks about .260 rem, 6.5 x 47 lapua and 6.5 creedmoor. These all look like great stalking calibres, firing 6.5 mm 140 gr bullets at 2900fps. i think they would be great a compromise between 6.5 swede and 6.5 x 284 norma. flatter shooting with less barrel burning than the 6.5.
but a part of me says we have loads of calibres already. why not just choose a 270 win. (coming from a man with a .243 a 7mm08 and a .30-06 maybe thats a little rich).
