I do the same. Carry at least one rifle when traveling in a common cartridge. I also have a 280 Improved being built. Actually asked for a 270 or 280 and let the gunsmith talk me into the improved. He said it was way better. (That means he already had the reamer)
Like a true loon, I said sure, go ahead.😊
Well, at least, now, the good news is that you can buy brass if you don't want to enjoy the range time doing lots of fire forming.
