Glad most recommend 240 grain bullets as I have a bunch of them around.
Planning on loading H110. Somewhere around 22.5 -24 grains. will start with the 22.5 grains. trying to decide what primer to use.
I would stick with jacketed bullets in the 240 grain range. I don't think lead bullets (even hard ones) are recommended for the Ruger due to it being gas operated. I had one quite a few years ago, and I recall at the time that people were having problems with the gas port getting crap in it from the lead bullets, leading to malfunctions.
