I was gifted with a nice custom .338-.280 Improved in a custom Interarrms action a few years ago. It has proven to be very accurate with a 210 Partitions, 200 ABs and 185 TTSXs. It is one of the last two rifles that I will ever part with. After messing with fire forming various .280 Remington and .30-06 cases, I now just buy Norma .338-06 brass and fire form cases to my chamber during load development and hunting.
