I have been wanting a new rifle for a while, and I am stuck on .270 (I LOVE .270 WIN). Most of the rifles I have been looking at are offering some fairly new chamberings (.280 AI, 28 NOSLER, 30 NOSLER, ETC) and I have been Intrigued by the .280 AI Specifically. I almost bought a rifle in .280 before covid hit, but I decided not to due to my lack of knowledge of the .280 at the time. Now with Covid behind us, I'm wondering if it is even worth it to get into a fancier cartridge like the .280 AI, or if just sticking to what I know is the better option. I am open to opinions. As I said, I love the .270 Win and I'd be open to adding one more to the gun safe, but I also like to explore options, and it seems like the .280 is very popular right now. I think one of my biggest concerns is finding brass for it as it is pretty $$$. Is it worth it? Or is it just a fad that will die off? I have also read that fire forming .280 Rem brass in the chamber is in option for procuring cheaper brass, is that even worth the trouble?? All input is appreciated.
