Hi Lon, the 89 is a bit lighter than the 88 too. But I am a bit of a wimp so I might get a bearer....Hi Kevin, As you know my wife hunts professionally with both a Heym .450-.400 & .404J. She is accurate up to 100 meters with her Heym .450-400. Her 88b weighs 4.825kgs, loaded. She is comfortable carrying that weight day after day. Although she owns a M-70 in .375 H&H it rarely sees daylight.
Like yourself she has a great desire to own a 89B in .470 Nitro. I have little doubt that sometime in the next two or three years her go to rifle will be a "Heym 89b in .40".
I'll PM you about hunts your side.
