I've never shot a hawken but can tell you thatI love the musket nipple on my TC Woods Rifle. They're bigger for one thing and easier to grab. I also see no reason not to get more firepower. It can't hurt anything. They're also not much more expensive than the no. 11's. I've never even used 11's.I switched out the nipple first thing whenI got it.

I'd love to buy one of those guns for the more traditional hunting. It doesn't sound like I could ever talk myself into it though. I'm glad you like yours.
