Six Guns by Keith.

I know there was a post about this in the past. 

I just saw in my current issue of Handloader magazine that Wolfe Publishing is reprinting this book and it might be available again.  I think they sell them on their website also.   Just an fyi for anyone looking to find a copy.

DEERHUNTER. Thanks, I've been trying to find a copy of that and hell I was there too. My library can't even find a copy of the latter. They got one of sixguns and it was in pretty rough shape. POWDERMAN.

  Powderman, I just bought a book of Elmer's letters...bought it from Amazon...they also have used books..don't know if they have the ones you need but it is worth a try...I have both of the ones you are looking for, and every couple years reread each...Good luck..You might check the Elmer Keith website, and ask if anyone there knows of any for sale...
