Hello,
A well respected gunsmith I know says TC stands behind their products better than any other and that TC's are very well made guns (the best, in his opinion).
I dont' know what I'd say. I've had a TC Renegade for almost 20 years and it has been an excellent rifle. Shoots as good today as it did the day I bought it, in fact, which is pretty good. And it's built like a tank. But it doesn't compare with today's inline's, accuracy wise, but, then, that's just because of old technology; it's not the gun's fault.
I've been shooting a Knight Bighorn for the past several years and it will shoot 1-2 inch groups at 100 yards all day long. And it's a solid little rifle. However, the old sidelock was just as easy to clean (despite what Knight's ads claim), and the Knight, in my opinion, isn't, really, any more reliable either. Keep the powder dry and the flashport clean, and, sure as the world, the gun will go off - old sidelock or new in-line!
My Bighorn will hangfire, and eventually not fire, if I keep shooting dozens of shots on the range without cleaning the flashport (and you you'll be hard pressed to get the breech plug out!) Keep it reasonably clean, though, and it will fire every time, guaranteed. Same with the old TC and #11 caps. I can never remember a misfire, while hunting, with my old TC and #11's. It's as reliable as the sunshine.
What I hate about my Bighorn is the fact that it takes a special (expensive, easy-to-lose, can't-hardly-find-'em-anymore tool) to get the stupid 209 primers out after firing, on occasion! They stick in there like they are permanently affixed! I carry a pair of small needle nose pliers around now to accomplish this. It's a pain. Sure be nice to find a gun where the 209 primer just pops out EVERY shot! Seems like with all the whiz-bang inventer engineers out there that someone could come up with a gun like this. Maybe they have already? Don't know, too busy trying to get the stupid primer out of my Bighorn!
A former sniper tested some in-lines a while back and claimed that the TC's have the best open sites of all guns he tested; the Remington the best trigger, while the Knight tested was quickest to get sighted in. Don't remember if he tested any CVA's or not.
The key to good accuracy is to experiment with bullets and loads and to swab the barrel clean after every shot. Also, keep powder charges, to 100 grains or less. Some folks may beg to differ but no rifle I've ever shot was MORE accurate with 150 grains of powder than it was with 100 grains or less (My Bighorn likes 80-90 grains of 777 the best).
Also, take the advice of others here regarding moisture condensation. I learned this the hard way. You don't need to! Once charged, keep the gun outside during hunting season, don't bring it back into the warm house!
All this said, though -- and sorry for the ramble here -- but I think you'd be hard pressed to find a bad gun in today's marketplace, regardless of make. It's a competitive world out there and duds just don't stay on the market long! You can buy a hechuva lot of gun for a $200 bill if you do some looking around.
Just a few things that work for me -- take from them what you want....
Hope you find the gun that's makes you happy! Good hunting....Raven
