Things I liked:Bullet stays intact and should be good for punching thru bone. Things I would have changed:Bullet is very hard, hardly any deformation. Don't know if lead is wrong alloy or bullets were cooled to fast. Bullets are not round and this causes fps drop due to poor seal in bore. Pulled out 20 from box and all measured out of round. Looking at recovered bullets, you can see where the rifling is not uniiform around the bullet. What others should know:May just have gotten a bad bathch. I'd suggest measuring them and fit checking before use.
