My shotgun will eat pretty much anything but I usually use Win AA light target loads at bigger matches just because they are so consistent. I always bring along some Win AA 1300 fps loads in case there is a stage with a swinger or heavy set poppers/long steel.
Club matches it doesn't matter. Fiocchi, Win, Rem or Federal bulk packs. I have a huge pile of Win AA and Fiocchi that I bought a couple years ago with big discounts so that is all I have shot for a while.
9mm - handloads. Pretty light. I'm a gamer. Precision "Black Bullets" because they have been working very well for me for years. Very accurate and easy on the wallet.
Rifle - Usually handloads but I bought a couple cases of Federal 50gr ballistic tips on a 4th of July sale. Always full power because I want flat trajectory, more gas works a comp better, and I have an adjustable gas block. Has to be '3-gun accurate' with a hot barrel. Bonus points if it matches my BDC really well but I have an EZ-Dope so if I need to I can reference that very quickly.
