Partially due to a shoulder injury and partially due to age I was looking for a rifle in 257 or 260 lately and they just don't seem to appear in gun stores. I guess gun stores stock what sells, but I would think those mid range cartridges would be a lot more popular.
What makes less sense is that I have seen two dad's this year start their first year hunters out with 30/06s and both cases ended up with wounded and lost elk. My guess is that those kids would have had a better chance of killing elk with a skaller cartridge.
