field and stream or outdoor life has an article on the controlled recoil loads......remington and fedral have them out now.....fedrals are called powershok or something i believe.......they are actually reduced velocity AND bullet weight......and after 200yrds they dont have the energy to expand safely from what i got out of the article........in my opinion i dont think stuff like this should be on the market.....it just dont sound like its very good to me......i may be wrong but i dont think it will perform to good in hunting situations........
