Ok. Went to rent a set of gauges from elk ridge This threw me for a loop.

“The 280 Ackley Improved Original gauges which are 0.004\"" shorter than 280 Remington gauges and now the new 280 Ackley Improved SAAMI gauges which are 0.014\"" shorter and compatible with factory cartridges. Be sure you know the needs of your project before renting”

I’m taking the barrel off a savage 110 and installing it on a CDC CDG action. Guessing I’ll need the SAAMI guages, not the “Original”?

That’s 10 thou difference, quite a lot!
