I'd stick with either original. AI'd cases have less barrel life than originals and the small velocity increase with the same pressure levels isn't worth a shorter barrel life.
260 Rem gets about 2000 rounds of best accuracy from the best barrels. AI versions can reduce that by 30% or more.
Fire forming cases wears out barrels just like normal loads of the same type.
