I am just getting ready to load the first batch of 243AI loads in my freshly formed brass. Been doing a little reading and have read several places that you can us near max loads for the regular 243 as a safe start load for the 243AI due to the increased volume of the AI. Thoughts? Suggestions?

I am planning on starting with 58gr V-max and RL15 or RL19 or Varget. I have data for the standard 243 in all powders, I am leaning towards RL15 or Varget. Thoughts?
