Sorry OP, You made your point clear that your .22lr choice was Not for Defensive purpose...

OK, I have a Colt New Frontier 4" and 2 pistols. They all shoot something better than the next. For example my Colt really likes standard velocity CCI. My Wife's SIG hates them. Her Walther P22 will eat everything and give you results.
Go to Walmart and pick yourself up a bunch of brands and see what shoots best for your firearm. Best advice I can give. It's not like it's going to break your bank.
