Hitting the mark and right spot are hard to do at 40-50 meters with a bow, there is a lot more chance of inaccuracy due to wind, glare up hill down hill etc. i dont do it out of pure chance you stuff up and you dont often get second chance with bow, i only hope those guys that shoot from 50 meters are the best of shots and only do it under the best of circumstances as a wounded boar can be dangerous not only for you but some other poor sod that stumbles upon it over the next fews days or weeks until it dies a horrible death from septesemia etc. If they are that bad a stalker that they have to release at 50 meters they should be carrying a hand cannon. For me its the chase and stalk that i remember not the release so to stalk closer means i have a more memorable experience than lobbing arrows from a field away in the hope i injure it bad enough that i can walk over and finish the job.
What poundage do you use on Buffalo i have a jennings 85 pounder and i use beeman 340 camo wrapt with beeman carbonhawks inside them for extra weight and tip them with satelite 3 blade fixed. Total weight 870 grains. I find it goes right threw buff due to momentum even if overall speed is down a tad 290fps
