Lots of good points here. In my opinion, the 270WCF is still the king of cartridges for deer sized game, hunted under typical conditions. The blend of velocity, recoil, trajectory, and availability is really as hard to beat now as it was 100 years ago.
The reason why it's not the "go to" for so many these days is that it isn't a great dual-purpose round for those that are part-time shooters and part-time hunters and aren't interested in having a safe full of different rifles. Guys used to would have their 270WCF for killing and other rifles for their range days and varmint time. The younger crowd want's to do it all with one chambering and today's marketing tells them they can. They want to go shoot the longer range steel with moderately-priced, higher-BC ammo and also be able to go hunting the next day. Many (but not all) young guys that are just hunters don't care as much, but they see how their buddies are having good success at the range and in the field with their Creedmoors and .308Win rifles, so when they buy something new, they often figure that they might as well go that route, both to take advantage of all the ammo and because those chamberings are available in all the new rifle models. That begins to weed out the purchases of some of the older, more traditional, big-game rounds, especially those with slower twist rates.
