.38 Special: 158 grain Lawman very accurate and feels close to self defense loads, 130 grain FMJ UMC, light recoil and shoots very nice out of any of my .38s
9mm: Any flavor of S&B, I started shooting it in Germany as it was the cheapest and easiest to find. I've shot thousands of them over the years and never had a problem.
PMC makes a nice accurate 9mm load, it is light recoil and accurate. The Glocks loves them some PMC.
.223: Most anything seems to work but the prefered is Federal 50 grain JHP. My Stag shoots those into less than 1" groups. The Remington 700 shoots these real nice also.
