Since you want to use the same round for both handgun and long gun, I think you are on the right track. Any of the premium 230gr rounds will do.
If it expands at range, great. If it doesn't you will get a through and through.
Up close and personal, the 230gr may over expand, but I have done a good bit of testing and even when the bullet over expands it still does a nice job of penetrating and a 451 hole is not that bad.
One day, I shall come back. Yes, I shall come back. Until then, there must be no regrets, no tears, no anxieties. Just go forward in all your beliefs and prove to me that I am not mistaken in mine.
Never cruel or cowardly.
Never give up. Never give in.
