Im going to immediately disclaim myself as a complete newcomer and am really looking for answers here but may come across as dumb in my question process. Im in the process of building a new rifle for no other reason than I just want to try something new. I chose a savage as my base because I want to do most of the work myself. I had originally thought 270 WSM or 7mm WSM
which is still probably the road I will take, but recently stumbled across the 280AI and am now considering possibly building that instead, mostly because it is unique and yet very powerful. but this isnt about discussing why I should do one or the other but more to address my questions about reloading for the 280AI. Currently there is one supplier of 280AI brass, Nosler, which from searches I have found is quite good, and also really expensive and almost always backordered at Midway, amongst my searches I also found that you can chamber and fire standard 280rem factory rounds to make AI cases, now for my real question. I can get a box of cheap Remington blasting ammo in 280rem for $28 at midway so heres my thought, can I use this to fire form my cases for the 280AI build while breaking in the barrel and then reload em with the good stuff for hunting and targets? If so what is gonna be my expected case life/ success rate fire forming this stuff? Is Remington brass of decent quality? Or should I bite the bullet and buy some Norma cases for the 280Rem and fire form those? I have also heard of monkeying with Lapua 30-06 brass but among other problems doubles or triples the work. What in the long run will be the best solution? This is just a thought experiment, I may still go with the WSM especially just for availability of components but thought this was a really cool alternative. Like I said, Im new to this so please dont be too hard on me.
