Hello,
I personally would go with a break open style. The Thompson's Encore is a great gun. So is the Omega. I considered both when looking at purchasing a muzzleloader but choose the H&R Sidekick (break open style also). I did a lot of research on the topic incuding several visits to local gun shops. I decide that my fat finger where not suited very well for the Omega style action. With that style action to get to the 209 primer cap I would have to use a pimer puller tool. Also to load the gun I would need a primer carrier. (Most primer carriers I've seen include a primer pulling tool). Either way thats one more thing I would have to buy and carry with me. The Encore pops the primer out automatically. I tried to avoid anything made by BPI, which includes CVA, Traditions, Winchester and New Frontier ( I believe Remington also), due to the minor Spanish barrel controversy that going on currently. I know that there are a lot of guns out there that are made by BPI and they are working safely. However many Ford Explorer owners drove their trucks on Firestone tires with out a problem too though it didn't necessarily make them safe. Check out the link below

Or go to

I orginally narrowed my choices down to three guns, the Encore, Omega and Sidekick. The Omega was eliminated due to my fat fingers. That left me with either the Encore or the Sidekick. Now the Encore is an excellent gun and Thompson's support service is second to none in the industry. However I did not want to spend that much for a gun. The H&R/NEF (A Marlin gun company which has excellent service also) Sidekick is made with rifle grade steel using the same process they use for all there other rifles. The gun is also made here in the USA! It is uses plastic re-usable primer carriers to hold the 209 primer. It makes replacing the primer easy. Finally the price on the gun starts at $159. I could buy three of them for less than the price of one Encore. (
www.Cabelas.com) or Gander Mountain.
I just carry a couple of the carriers with primers in them in a film container and when I shoot I just replace the carrier with a new one and put the used one in my pocket. I just recently purchased this gun so I don't have a lot time shooting it but it seems like it very accurate. My primary use is hunting. I took it to the range this weekend and had no problems at 100 yrd using 245 powerbelts and two 50 grain 777 pellets. The gun will except magnum 150 grain charges and has a 26" barrel.
Now if your looking at a gun for hunting I would seriously take a look at the Sidekick. If you a competition shooter I would probably purchase the Encore. Either way do your own research. I would at least drive to a local H&R dealer and look at the Sidekick. It might just save you a lot of money.
Good luck.
