I have a non windowed magazine so I’ll be putting it in the first band. Thanks for clearing that up. Now if I can just get an idea of using powder load range. 33 to 35 for lil gun sound right? And what range for H110?
I would have ventured 34-36 Lil Gun at 2.18 COL. Watching for pressure signs = case head growth (CHG), you might be able to noodle a little above 36gr. If you have a micrometer, take it to the range with you. measure a few case diameters for their widest spot, shoot the rounds and remeasure. If that widest spot jumps more than .001 after shooting, you're done going any higher. Wildcatter would push that sometimes to .0015 but .001 is a good rule of thumb, unless you have as loosey goosey chamber. It will falsely indicate excessive CHG even with moderate loads. I know because I had one. Chambered and ejected just about anything I fed it but the CHG was sometimes alarming where other members, using the same make and model upper, had less CHG for the same load, same COL, same crimp, etc. It was one of the reasons I got rid of that barrel. I actually miss it sometimes to this day.
With H110, figure on a grain higher charge weight from my experience. Having a hot primer is essential with H110.
