RE: 250 shockwaves
I haveheard nothing but good reports on the 259 shock waves. BUT!!!
I have shot 2 deer with them this year one right through the heart who wnt about 50 yards and never found a spot of blood. It's too band as I love there accurecy and the way they load (after 200 shot break in). I'm not in a position to judge yet but I am going to keep using then for a couple more deer and see if it improves.
