I have limited experience hand loading so I just want to make the best decision and go with it. That way I have a solid platform to build from.
I have never chambered the 280 or the AI version in a SP, but I have had SP's in 284 Win, 7mmRem Mag Imp, and the 7mm Dakota (as well as 260 Rem, 6-284 & 6.5-284) and they have all shot great.
If you are going to have an 18" for unlimited and a 15 for production then I would go with the 6.5-284 for 15" and the 280 AI for unlimited.
FWIW--I will be shooting a 6.5-284 for production myself and I will be shooting a big 7mm for unlimited.
