Used one for over 40 years as my most used deer rifle. I still use it because it works very well.
There is a trend among shooters to put down many cartridges or rifles that has no logic or reason to support the criticism and mocking that often occurs on forums like this. Those "put downs" are most often the efforts of insecure, or uninformed, or inexperienced hunters who read too much and hunt too little. If you want to promote the "modern" cartridges (like the Creedmoor or the short magnums as examples) as improvements over older rounds, go right ahead. But anyone who tries to convince you that hunting with the cartridges that have been doing exactly what is needed on game for anywhere from 40 to 120 years is going to hinder your success, is just blowing smoke or trying to pump up his own ego. The .270 (and several others that many try to disparage) is a perfectly fine hunting round. It's even better than it was 50 years ago (as are most "older" rounds) because of new bullets and powders. If you can't kill it with a .270 and a good bullet, you can't kill it with the newest and most exciting marketing star of the day either. If "advantages" that will never be detectable in a hunting situation seem important to you, then the subtle changes that many newly designed rounds are marketed as revolutionary and new may be fun for you. If you need to be "modern" just because - go ahead. But to suggest that the .270 is somehow not capable and should be declared obsolete, is just dumb.
