I would put them on any game in washington with the correct application of accuracy and weight.
Same here. I'd hunt elk or moose with BTs of the correct weight without a second thought.
I've usd BTs for probably 20 years. I've never had one stay inside an animal. I've never seen them work anything less than perfectly.
My brother uses them also. They've worked great for him for a lot of years as well.
I think a lot of the badmouthing of BTs comes from dudes that are just regurgitating something they heard some other dude say.
My experience with BTs has been nothing but positive. If they stop working (doubtful) I'll start shooting something else.
