223 AI AR upper

[REELDOC]

Just had an AR upper re-chambered to 223AI. The barrel is a 1/12 twist. I have 40 grain V-Max and Sierra 52 grain HPBT to start with as well as other basic 55 and 60 grain bullets.

Load data for an AR based 223AI is unobtainium so I thought I would ask for your suggestions. I can't find any OAL data either.

I pretty much have all standard 223 powders on hand but do not have H335 which seems to be a standard.

Thanks in advance for your help.
