Peterson 280 AI dimensions please

[8andbait]

Hi, can someone with Peterson 280 AI brass let me know what a loaded round measures for neck diameter? I assume .314-.316 but I want to be sure the reamer will work so I don't have to turn necks.

Thanks, Gary

I got .314 on loaded Peterson .280 rem fired formed to AI, if that helps.
