perhaps tapped on the shoulder.
I know what you mean. Case capacity
and bullet diameter favor the .270 a
little. But I have seen no difference in
the field. I had a frontal shot on a big
whitetail a few years ago and took him
at 275 yards with a 140gr Nosler Partition.
Shot through him stem to stern. Piled him
up like hit with a freight train. I hunted
with nothing but a .270 for years. Started
with the 6.5x55 about 10 years ago and
have had just fabulous performance from
it. Like you said, no practical difference.
Especially at past 250. Those high BC's
and SD's really pay off here.

P.S. you can load a .260 or 6x5x55 to the
same pressures as a .270 if you want to.
.270 is really a "magnum" cartridge with
no belt. SAAMI 55,000 PSI factory loading.
Then the line gets pretty thin between these.
