It's possible (but unlikely) that you have a #10 nipple or one that's defective. I bought a brand new #11 nipple once that the caps would literally fall off from if you were to tip the rifle upside down. I'd buy a new nipple (I like Uncle Mikes) but the TOW nipples should be fine, just make sure you get the correct thread for your rifle.

Yep...I've pushed it down very firmly. The nipple is factory from TC. It came with the 209, musket, and #11. I put it on and it will stay on if I tip it up but I can hit it with a feather or blow on it and it would fall off. I need one like today but since no one has them I will just have to order and hope it gets here before season.
