The classic load of 148g wadcutter and 2.5-2.7g Bullseye is uncomfortable for me after 50 rounds thru an Airweight. There was an article in the 1981 NRA Handloading manual suggesting that you could go much lighter, subject to making *sure* the bullets were always exiting the barrel.
As I recall, they found that .55g Bullseye would reliably expel bullets from a 2" barrel, but they used .75g for a margin of safety. For a 6" barrel they were suggesting 1.25g Bullseye. I've used that 1.25g load in a 2" and it's like shooting a .22, except that the bullet tends to tumble.
Nothing magic about handloading, I would suggest the OP look into it. Follow published loads from reputable sources. While the Lee Loader type tools are fun, you will get tired of pounding on things so pony up for a basic single-stage press.
You could also look into primer-powered wax bullets.
