These things hit hard @ 27-55 yards for sure. Take a look at the deformation of slugs after hitting a spinner at 27 yards and grouped on same tune for my 18gr pellets. Of course holdover is different but man it shows promise.
I'm going to knock some critters out that need took out.I load up Altaros slugs when I want to use my .22 LR active targets. My usual .22 pellets don't carry enough energy.
