Bronko, have you ever used those Sierras on game?

The reason I ask is several years ago I tried them in my Lyman Mustang and they shot real well. I then had an exchange of e-mails with a technician at Sierra about using them in muzzleloaders. His opinion was that they are very tough bullets and suggested that they would be great if you hit bone, but could not rely on them to expand on soft tissue.
