Good thread, Gryphon - jungle is jungle, no matter where in the world it's located.

The Hydro with a BC of .450 - I'm having difficulty with that high a number. I would believe something in the range of .275 to about .330, though.

Not only the nose shape, but the bands on the shank are brutal to the BC. The bands create a lot of additonal drag - called parasitic drag due to the eddies in air movement they cause by each and every groove, nothing smooth as in laminar flow. Note the difference between the Barnes "X" bullets of old, the smooth ones, and the TSX now used. There is a huge drop in BC due to the bands, even though the TSX of the same weight is even longer.

Still, in a .35 Whelen, a good shot will not have difficulty with shots to 300 yards - even 350 yards. One merely needs to practise at those ranges. Shooting at 50 or 100 yards and reading drop tables doesn't cut it.
