Good info on the 500 grips... may have to see if brownells sells them as parts... my 329 isn't horrible with 300 cast, but its really close to horrible.
We are loading 270 hard cast GC right now so it doesn't beat the gun up quite as bad.
If not that I'd go barnes of course, but moose seem to not take a lot of killing... Me, I'd grab my 329 and our 270 cast or the mentioned 300 cast, put the first one in the crease through both lungs low, and the second in the shoulders and be done with it.
I do know our 329 is very easy accurate enough for 50 yards though the sights leave a bit to be desired when I'm shooting paper at 100 with it.
