Did you read the thread "BP version of an SAT analogy"? It is so funny that you would post this right after that thread. Just drives home what I was talking about. Seriously though, I don't think they should be that tight in a new gun with a clean bore, unless there is some manufacturing residue in the barrel that you failed to remove. I have heard that you MUST properly clean the bore before using a new gun for the first time.
Or maybe you bought the wrong size sabots.
