I also have a nice Marlin made Glenfield 30 that i rescued from a pawn shop a couple of years back for $121 and change OTD. In retrospect, I think it would have taken every deer, WT and Mule,,that I have ever killed excep for four long range shots.
I'm on the downhill slope of life and it seems I may have wasted a lot of money chasing the perfect deer rifle. Dad's one and only center fire rifle was a Marlin 336 RC in .30-30. Uncle got along just fine with a Marlin 1936 in that caliber. He ate a lot of venison. Makes one wonder.......jack
A 30-30 through the lungs is hard for a critter to stand.
