I think the super is better because of less pressure. The nature of the way a Glock works makes it more suitable for higher pressure. That said there is little differnce in real world performance between the two cartridges. Running at 28,000 vs 40,000 can only increase the life of the gun. I am loading my .460 to around 35,000 at which it will live forever. When I think I need more I can always step up. Both cartridges are completely capible of taking deer or hogs. The Rowland at the top end can take elk and has done so. reflex264
