I read cape buffalo can only be hunted with a 80lbs bow, and most recurve bows are only 60lbs maximum. Cape buffalo can only be hunted with a compound bow? A 150lbs crossbow is enough for cape buffalo?
I know that hippo, elephant cannot be hunted with any bow, but I'm interested in game like kudu, impala, wildebeest.
Well first off it depends which country. For SA, for the animals you list you would need a long bow, re curve bow or compound bow of 60 pounds, launching an arrow of minimum 500 grains with kinetic energy of 60ft/lbs, up to blue wildebeest.
Long bow, re curve bow and compound bow is legal. (For cape buffalo as well as long as it meets the minimum requirements see below)
Crossbow is illegal no matter the poundage.(The reason is the arrow length minimum is 50 cm)
medium game, including reedbuck, impala, blesbuck, warthog, bushpig, springbuck, and nyala (Category 2)-
(i) bow with a minimum draw mass of 50 pounds;
(ii) bow generating a minimum kinetic energy 50ft/lbs; and
(iii) minimum arrow weight 400 grains;
large game, including wildebeests, kudu, gemsbuck, zebra, waterbuck, sable, and hartebeests (Category 3)-
(i) bow with a minimum draw mass of 60 pounds;
(ii) bow generating a minimum kinetic energy of 60ft/lbs; and
(iii) minimum arrow weight of 500 grains;
Cape buffalo (Category 4)-
(i) bow with a minimum draw mass of 80 pounds;
(ii) bow generating a minimum kinetic energy of BOft/lbs; and
(iii) minimum arrow weight of 750 grains;
giraffe (Category 5)-
(i) bow with a minimum draw mass of 90 pounds;
(ii) bow generating a minimum kinetic energy of 90ft/lbs; and
(iii) minimum arrow weight of 750 grains.
In addition to the above following conditions apply-
(a) in the case of mechanical broad heads 5% additional kinetic energy is required for Category 1, 2 and 3 wild animals;
(b) broad heads must have at least tv.o cutting edges; and
(c) the minimum permitted arrow length is 50cm.
