A worthwhile exercise SD. At least you know where you stand performance wise with regards to the ammo you have. The amount of .22’s I’ve got through over the years, just trying out different brands and types. Many I’ve found to be crap, so I plink them off for practice if I don’t consider them of serious use to me. The good ones I use for live quarry. Trouble is, I like to try something different if I come across it, and it’s often poor. Sometimes though, surprisingly good.?
