Yes, and sorry about that. Even tough all the previous is only loosely related, what you have to realize is the gents on this site are thinkers. Meaning if you suggest something your going to get an answer, and you'll see, these guys are going to put in their data, to what I've suggested and if you will put up with some deviations, you will learn allot too. But the answer to your question is yes, big time..
.451 jacketed bullets will certainly work. If you're looking for inexpensive stuff to get in some volume shooting they may be just the ticket. The responses you're getting from some of us which seem contrary are more related to our search for some self defined ballistic goal, either accuracy or terminal effect. Don't let that slow you down.
