Forum Boss said:He needs a bag that will fit the Caldwell front rest -- to replace, presumably a tri-lobe bag. I may have to modify the side plates a bit, but you should be able to use a SEB, Edgewood, or Protektor front bag. They are all good. I personally like the SEB bag because I don't like to use powder or lubricants. The SEB front bag has a microfiber fabric on surfaces that contact the gun. This stuff is as smooth as silk, yet durable. The Edgewood is very well made, but some guys say you have to be careful not to run it too hard.
