@ Ridge Runner, What is your reasoning on maximum ranges here? Accuracy or penetration?
Both actually.
Back when I was 3D tournament shooting, there would be side tournaments, 0ne particular and very popular was the 100+ yard 3D buffalo(bison) target.
Attached to the bison's scoring ring is a 2x2 inch exploding target. Explode the block and you win a table prize pack.
In hunting we want to be accurate and we want more than "enough" penetration to make a clean kill.
I may be able to hit the kill zone be it at 20 yards or 100 yards, but if the bow weight isn't strong enough or the arrow lacks in performance at over 50, 75, 100 yards why attempt to make the shot?
My longest shot on a deer is 61 yards, facing me, it went 5 yards and down. Bow weight 65 pounds; Arrow: Victory, VForce, 350, 322 grains including the 100 grain, cut on contact, G5 broadhead.
Kudu, eland, wildebeest are not whitetails, thus as a bow hunter going to Africa after an "elk" size animal, which I have never been able to go after with a bow...yet..; I am trying to put as much information together to get an idea on what I need to do to prepare.
Back in my "younger days", I use to shoot a York 80 pound draw bow, using 400+/- grain arrows out to 90 yards. Those days are gone.
Now I shoot an "advertised" "70 pound" Mathews bow at 68 pound max draw weight. My 450 grain X7 Easton Eclipes arrows look like logs flying through the air.
Question: Using a 450 gr arrow, traveling 270+/- fps, with proper shot placement:.....will this properly kill a kudu, eland, at 60 yards?
My bad...I should have communicated better,...going after PG gemsbuck and smaller only, "personally", I would be comfortable with shots 60 yards and less using only my 322 grain arrows only.
If I was going after anything bigger than gemsbuck; ie kudu, wildebeest, buff, and under I would be using the same 450-500 grain arrow weight for all game.
