Whatever shoots best out of your gun and that you shoot the best. True Blue may not be my first choice, and in your LCR you can easily load the top end of 32 Mag...AA5 and AA7 will bring you 1300 fps plus.....which only matters if you can hit something with it, lol, and the LCR can be a handful with hot ammo.
I'll add this, because this argument drives me nuts. Fact: "factory for self defense" is a myth started by Mr. Ayoob in the 80s to sell magazine adds for ammo companies....he has doubled down over the years, and still talks about it in his **paid** speaking engagements....he has never been able to produce an actually documented court case where a conviction or a sentence turned on a reloaded defense bullet, and neither has anybody else. I've had a standing offer on the interwebs for 20 years, I'll shoot a nice chunk of cash to the first person who can produce a documented court case with case number, transcripts, etc. Nobody has been able to take me up on it. You will see after this statment the normal "well I heard...." and "I was a cop and I saw....", but none of them will be able to produce a single documented case reference. So ignore that mythical invented deal right there, and carry what you want.
