Is there an accepted definition for "Long Range", Or is it basically any distance difficult for the platform?
For example, 100 yards with a 12FPE springer is long range for the caliber and power. Just curious.
I don't know if there is, but I definitely agree that in practice it is specific to the tools at hand. I too have things that shoot stuff that could not be used for 100 yards. Conversely, for a .408 Cheyenne Tactical, .50BMG or .338 Lapua, 100 yards is hardly long range. You could 10X that in some cases.
For air rifle, I'd be happy to agree that 100 yards is always "long range", but as you say, for a springer, 100 yds isn't realistic, so 50-75 yards might be "long range" in that case.
