I haven’t had a .22 for decades. Not only that, but it will be a springer - .177 and PCP I’m ok with, but a .22 springer...

I will be one of the first with the advice “every gun / barrel is different, you’ll have to test”, but I also remember reading that lighter pellets are better in springers. I’m not looking for “cloverleaf” at 25yds, but 20mm would be nice. So heavy, light, or in-between?
