It really looks like you guys have a great collection of toys assembled. A word of caution here. This fest is not for those who think a .30-06 kicks like hell!
I have posted this linke before, but here it is again. This will take you to Chuck Hawks' recoil table.

I am seriously thinking about such an event here in Pennsylvania. My buddy with the .460 says he is not interested in having others shoot his rifle, only me (I am the only one who is dumb enough to sight in his scope for him).
Have a blast, guys.
