Hello All,
I am new to the group and kind of new to the TC line of firearms. I am having issues with an Encore that I purchased second hand. I shot it the day that I bought it and knew that the tigger is VERY light, but it shot great and was very accurate. By accurate I mean 3 shots in one elongated hole at 100yrds. After about 5 rounds through the rifle I am now having misfires about every 3 rounds. I can pull the hammer back and fire again which will go off the second time. Any suggestions on how to fix this? I would really like my rifle to be dependable during hunting season.
Thanks, Adam

Adam,
First and foremost - does your rifle have an aftermarket hammer extension on it? If it does, take it off and see if that solves the issue. Some people don't realize the trajectory of the hammer extension, and they end up lightly scrapping the bottom of their scope ocular lens bell. If it's not lightweight aluminum, it might also be contributing to the misfires due to the added weight added to the hammer spur. You can fix that second problem by installing a heavier hammer spring from Bellm.
You may also have headspace issues. I suggest checking out Bellms page here to address that issue:

Change of subject, since you mentioned it:
Also, since you said your trigger is VERY light, does your hammer rebound properly?
If the trigger pull is very light, the trigger/sear may not be strong enough to rebound the hammer to half cock after you take your finger off the trigger after letting the hammer down manually. If that is the case, I'd be very careful with that firearm, and I'd have the trigger looked at / springs changed to something heavier than 2 lbs. Bellm recommends 1.5 lbs as the minimum. His instructions are very adamant about this, and I've had issues with one of mine that I had to go with a slightly heavier spring. It's still awesome. Just not a hair trigger like it was before, and it's safe now.
All the best,
Glenn
If at first you don't succeed... buy newer / better equipment!

The first thing I'd check: The previous owner may have over-Bellm-ized the setup. I'm talking about super-polishing the sear/hammer engagement and creating a slippery-slope as he calls it. Insert a snap-cap, close the action, cock the hammer and push it forward with moderate/heavy hand-pressure. If the Hammer drops you've got a safety issue. Heavier Hammer springs will add to the problem. While you're at Bellm's site, check up on that. For super-light trigger pulls plus heavy hammer springs, he recommends going from a 90* to an 80* engagement angle.
If your chamber is too deep, the first hit shoved the case forward, the second hit had enough force to ignite the primer. Take your barrel off, and shove the loaded round into the chamber as much as you can with your thumb griefing all you can muster. Then take a steel straight put it across the breech end and see if there is any gap under the straight edge and the case end.Shimming the bushing forward will only work so far. You still have to maintain .0015 to .0020 gap between the bushing and the barrel's breech end. Cases going too deep can be adjusted by adjusting your dies to move the shoulder forward to keep the case from going deep. Within reason, you can push the case back a little further to account for excessive headspace. Shimming for one barrel may create problems with other barrels you may have and want to use on that frame. I'd suggest adjusting the bushing for the shortest gap barrel still leaving .0015 to .002 gap for it. Then use die adjustment on the rest of your barrels. Unless, of course, you don't mind having dedicated barrel/frame combos.
Failure to fire can also be caused by insufficient lock-up--locking bolts not going in deep enough. You can read about that at Bellm's site as well.
