Not all TX's or 97's are made equal. Some just seem to shoot that tiny bit better. 8 TX's and 1 PS so far and only 1 was not a good one(TX with a bad barrel). I have shot half a dozen other TX's that were all good as well. I picked up 1 HW97 and it was a bad one. It's the law of averages for me. I now only have 7 TX's and I would suggest finding a used MarkI or MarkII.
