shooting one of these animals. There, that said and out of the way, lets talk a bit about ballistics.
I dont think that any normal large caliber is going to do much harm (lethal) to a sasquatch. You need a good heavy elephant hunting round or bigger. Something on the lines of the M-2 .50 cal round or a 20mm. AND then the shot will need to be placed in a lethal area (brain, heart, lungs). Try doing this, in the dark, shaking, and with your mind racing at 100 mph. Not an easy task. Then you have to take into account, his clan members, will they attack? Will they even so much as let you walk away? How many of them within screaming distance will there be ?? *throwing in the unknown factor*
Forget it, concentrate on finding a naturally deceased corpse, or a good clear photograph (the odds are better i think).
We are talking about an animal whos weight estimates far exceed 1000 lbs ... thats half a ton of muscle and bone, very little fat reserves. Compare a prize bull at 2000 lbs, not a very big animal when you compare them to sasquatch, a bulls bulk is in the chest and abdominal regions (skinny legs) (not so with a quatch, they are bulky all the way thru ).. will a 30.06 springfield fired in the daytime at a marginal range take one of these out (bull)? Not usually.
See one, and you'll understand.
