I want ultimate, not the fastest or the longest barrel life or any one thing, that can all be researched, as stated before I want some opinions, future responders please read the op before commenting
In your arrogant haste to be dismissive, what you missed is that I was trying to help. NO cartridge is the ultimate, they are all a compromise of the things in my first post.
If you had provided details of exactly what you wanted to accomplish with that cartridge, we could have helped. Instead guys are reduced to telling what works for them, as they have no idea of what you want to do.
