Gday Ian.
I strongly believe that the arrow is more important than the bow when it comes to penetration on game.
heavy arrows with a strong 2-blade broadhead and high FOC that are properly tuned to the bow are a great start. I base this on a small amount of personal experience and the fantastic penetration testing/studies that Ed Ashby has done over the years.
Some people harp on about "minimum" poundages for certain species which I beleive is the wrong way to look at the whole thing.
I beleive the more sensible approach is to say "what arrow setup at what speed will garuantee good penetration on the game I am hunting."
The bows poundage then becomes less important. High poundage doesn't necessarilly equal high speed. One hunter could be pulling 75lb with a slug of bow, shooting 450gr noodles that are poorly tuned with multi blade broadheads. Another hunter may only pull 40lb but his bow is an efficient design with well tuned heavy arrows setup as above.
I know which one I'd rather use.
The above hypothetical is extreme but it emphasises my point.
As for shot distance yes heavier arrows will drop faster but my personal limit on game is about 15yards - not enough distance to notice any difference in drop.
I am confident that I'll have no problems getting passthroughs on the goats, deer and pigs that I will be after with this setup. I doubt one could cook up a much better performing game arrow than these without some major work.
