From what I have heard, it seems as though the Deerfield may be best for you. It is not as powerful as a 308, but at short ranges, even as long as 100yds, I am pretty sure that you would not notice much of a difference. Then again, ammo would be a big difference. Which reminds me, a Deerfield will pretty much take any 44 mag ammo that you can stick into it. The action is extremely strong, but the chamber is not long enough for the really heavy stuff.

<br>That said, I would still go with a Guide Gun. If you are worried about safety, then keep the hammer down, or better yet, work the lever when you are ready to shoot. A 45-70 really gives you alot of flexibility. Lighter factory loads will drop a hog without knocking you out!
