Just bought a box of 60gr Aguila Sniper Subsonic to try something new. Opened the box and was kinda surprised. It is the length of a .22lr but the brass is the size of a .22 short. It makes sense to have to limit the case size to accomodate the 60gr bullet, but just weird to see. Anybody used this stuff. What is the relationship between sub / super sonic (besides the somic boom haha) as far as accuracy with such a heavy bullet? We'll see if my Marlin 25 likes it!
