Long sad story about how all this came about but I was just able to op check my Dan Wessons after better than a year. One seems perfect. The other still shoots sweet but I'm seeing some ragged holes in the target. Wondering if that may be indicative of a timing issue. Any help appreciated as always.

Shoot it from a rest, single action, slow fire to establish a benchmark for best case accuracy.
If "ragged holes" means a not clean hole for each round (keyholing?) I'd look first at barrel condition, clean, bright, shiny all the way through. No rust, scuffs in the rifling.
One more suggestion: If your Large Frame has the Power Control B/A, shroud and vent holes in barrel must be spotless and clean, clear of any powder residue or bullet shavings. Interior of the shroud and exterior of the barrel likewise.
Dan Wesson's Power Control system is a PITA!
I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

On the KD range in the Marine Corps we referred two rounds leaving shot holes that overlapped as a key hole shot. Its amazing how many times people have a completely different read on vernacular. However this is not the case here. Each round is leaving a ragged hole. As if perhaps the metal jacket has a ragged edge on it and the round is not punching the paper cleanly. These were jacketed flat nose rounds. I normallly don't like these rounds and would suspect that they might be the problem but the other gun was punching clean round holes.
This barrel is not vented but I actually have another 6" barrel I can try. I guess that would eliminate the possibility of a rifling or carbon issue. I suppose if the timing is off a little bit and damaging the jacket it will still to it with a new barrel. Seems like a good trouble shooting step.

Fired with new barrel and still had some ragged shot holes. About 50%. My 8" barrel is shooting perfect round holes every time so I'll put that one on it as one last check but it's looking like something other than a burr or carbon in the barrel. I was only guessing at timing originally but don't know much about it. Should only be effected by bolt, hand or the star on the cylinder I think. Just don't know much about it. I'll check back in after the test with the 8" barrel.

Take a look a the primes from that gun after you shoot it. If the timing is off very much, the primer should show very off center firing pin impacts. Also, are you seeing jacket material shavings around the forcing cone? If its that far off time to mess up the jacket, it should be showing signs of bullet shaving.
Anything worth doing is worth doing well.

Can you post a picture of the "ragged hole" target compared to the "clean hole" target shot w/ the 8" barrel? Thanks.
