50 pounds would be a real big one, and 35 pounds more typical. They are very narrow side to side. Probably 6" of penetration would result in the broadhead exiting the far side. I don't recall their hide being anything difficult. I think this is a fine idea. This isn't to brag, but I have killed about 14, all with recurves. They are not a tough animal. Here is a tip- if you blow a shot, just sit tight. One or more will usually go the wrong way, and in a few minutes will come back though where the herd split up looking for the gang. Many of my pigs have been these lost ones.
