well guys today I filled a 1 gallon jug of water and placed it in front of a box made out of wood. the face was 3/4 " plywood and the sides were 2x4s and the back was a 2 x 12 and i put a wet 4" thick telephone book in the box and I shot it from 200 yds away. i must say i would not want to be shot by these bullets there was a good sized hole all the way threw it at the back the 2x12 had a hole about 1 3/4" could not find the 300 gr bullet I used (3) triple 7 pellets and it works
