You are looking at a .177 stainless DC probe, through the transfer port of a CR steel breech fitted with a .177 CR barrel.

No Mark that is not right!!!!
If your bolt handle is locked down (as if you had loaded it). then the bolt handle
is too far back, which would also mean that the bolt has entered too far into the barrel.
It should not be able to go that far in!!!!
Which (IMHO) means.
A/ the bolt is too small in diameter.
B/ the lead in crown on the barrel is the wrong angle and too deep.
There are probably more reasons for this problem but A. and B. are the ones that jump out at me plus as I pointed out the bolt handle is in the wrong place.
I'm sure others will have more and better ideas but looking at your picture those three things look like high probabilities to me.
OOPS. Something else has just occured to me.
The T/Port holes are in the wrong place. This would only apply if it's an after market breech.
If you have a standard CR Breech and barrel then I doubt it is that.
Sorry Mark I just read your post again. Please ignore the OOPS. Part.
HTH.

IF that's not a Crosman bolt, then I'd have to guess that it is the problem.  Crosman barrel's port lines up with teh breech's port, so unless both of those factory parts were made wrong (little chance of that), then suspect the bolt.

Have you contacted Cothran to give him an opportunity to correct the issue?

Cothran made part. All of his stuff is cnc'd, and everything that I ever received was right on the money. However, I have had cone across more than one bolt that another tuner made that had port alignment issues, and off center bolt handle holes that led to the handle binding in the slot.
If what you have is one of Dons bolts, I'm more than sure that he will do the right thing.

If the O.L. is the same as a Crosman bolt probe for that caliber then the handle is in the wrong location.

Have you compared a stock Crosman bolt and handle to the DC parts? Just lay them side by side and compare them. Do a couple simple measurements. It should be obvious if their is a problem.

I also have used many of Don's parts and have never had an issue of any sort.
