I have a TC Penn Hunter with a hammer spring that may be loose. It's noticeably easier to pull back compared with my Traditions Perc and my Pedersoli Flinter. But it also has a longer throw. I never thought much about it until I picked up the flinter recently. It's not terribly easy but it fails to ignite about 1/5 caps the first time it strikes. At the range, it's no big deal -- it's just a good dry-fire drill. I can just pull the hammer back again & it usually goes off (yes, caps were seated well beforehand). But it was certainly frustrating when I took it out hunting and had it just "click" on quail or squirrels (smoothbore). Are these rifles known for having a looser spring? Or is it something that should be replaced?
