Funny you should bring this up. I bought one of these after they first came out, thought it would be pretty neat to have. I have had trouble with it every since. I got the barrel from the bass pro shop. It was kind of funny I went in looking for a .45 cal. and they said they didn't have one so I settled for a fifty but when they gave it to me I went to check out with it and as I was walking down the isle with it I looked at the box and to my surprise it was a .45 cal. I thought cool. Well, I got it home got some powder and bullets for it and went to range with it, this thing wouldn't shoot worth a sh$%. I tried different bullets, different powder charges and still couldn't get it to shoot. I sent it back to T/C and told them about it and they shot it with such and such bullet/powder and said it would shoot a inch group @ 100 yds. I tried it with the bullet/powder that they used and they lied! So I started to do some checking around and some research and thats when I started hearing the horror stories about the 1:20 twist rates that they put 'em when they first came out with them so I had it check by a gunsmith I know, yea thats right I had one, so that sucker went back again to T/C with a nice long letter and they sent me a new one supposeably with a 1:28 in it, but I am fixing to have it checked because I can't get it to shoot worth a sh$% either. I haven't put very much time into this one but its coming. I just read a real good artical about .45 calibers and what kind of bullets that should be used in them so I am going to give this barrel the bennifit of the doubt before I raise hell with T/C again. I have been burned twice with T/C factory barrels already and that kind of lets your confidence level down whole.
