Round not listed in manual ?
I am looking for load data on a 280AI. I was going to purchase barnes manual but found out this round wasn't listed in their manual. I wanted to try the 140 grain TTSX. Has anyone experienced this with their rounds? I didn't wanna use load data for another brand same weight as I'm unsure if the Barnes needs a crimp or something. I'm waiting to hear back from their customer service as well. Thanks for the input.
