I need help understanding the 280AI. Originally I was thinking of doing just one build on my 700 mountain SS but now I think I will build a 280AI on that rifle AND purchase a lighter recoiling rifle as well for fun shooting. The current rifle is a 3006 Remington 700 mountain SS. I will be rebarreling with a 280AI. The plan will be to shoot 120/140 pills. I have read an awful lot on the 280AI and I am just getting more confused the more I read. From what I have read is it used to be a wildcat round but SAAMI adopted it sometime ago. This means there has been a couple chamber configurations where factory 280AI ammo can work and other chambers it may not? I also am not understanding about how 280rem can be shot through it in a "pinch". Can someone please help me on what I need to know for this caliber? Can 280rem be safely shot in it and are they decently accurate assuming the whole rifle and barrel are accurate (I am talking sub 1 MOA). So for example if I built a 280AI and am able to get .5MOA groups with reloads, is there a high probability I could potentially find a 280rem load which will shoot decent enough if I ever need ammo in a pinch? I do reload so what will I need to load? Do I need a special die set to form brass or are there good factory options readily available? I don't mind buying expensive brass if it will save me from having to fireform brass. What twist barrel should I look into for shooting mainly 120/140 grain pills with possibly up to 160. Definitely no heavier than that. This will be a flat shooting woods hunting rifle for deer so I do not need high BC. I may also simply load it towards the bottom end of loads with 120s just for lighter hunting rounds to mimic a 7mm08. I have also read things about possible feeding issues due to the shoulder of the cartridge. Will this be a problem in my Remington 700 action? What else am I missing? Thank you for your patience.
