Need to get some loads going for my new Defiance .243AI. I've got some AI brass that fits the chamber well, so don't need to fireform for now. I'd like to try 85 grain tsx, 90 grain Nosler E-tips and 105 A-max's in it. Will be a deer rifle, so would prefer to max out velocities. Was thinking Magpro, RL17, H4831 and H414 might all be good powders?

What say you?

Thank you,

Joe
