One of four barrels a little "off"...

(Editing to clarify I meant Barrel SHROUD, not Barrel!)

So I had not yet got around to shooting the 8" barrel that came with a 6" & a 2.5" with a Monson made .357. Noticed a little problem when I first put the barrel SHROUD on, in that it looked slightly cocked off to the right, and sure enough, shoots a decent group, about 5"off to the left at 30 yds. Rats! The other barrel/shroud assemblies and the CZ 4" that I added all time or clock very nicely at 12:00 and group within the same area, windage wise. I don't want to crank on the rear sight to zero one of four barrels and then have to crank back when I change. Is there any solution or do I scope the 8" and call it a day?

Oh, and one other question; what was the brand and model number for the Pistol Pack Cases that came with these guns? I'd like to start looking for one.

 A new/used 8" barrel. May have been threaded wrong/crooked.
The shroud itself can't pull the barrel sideways unless it is loose in the breech end.
Any wiggle in the barrel when it's threaded in the frame to it's proper position?

Not sideways, rotational error, rotated slightly right of top dead center.

If you loosened it a half turn would it be left of center then?

Is the fault with the barrel tube, or the shroud?

What happens if you just thread the barrel in with no shroud?

Is it still "looking slightly cocked off to the right"? DON'T EVEN TRY TO FIRE IT LIKE THIS!

If the shroud is canted/leaning to the right then you will shoot left of POA. The barrel will still be aligned properly, it's the movement of the front sight to the right that causes the difference oin POI. is the hole in the rear of the shroud wallowed out causing the movement of the shroud?

Thank you for understanding what I was trying to say, I guess I did a poor job of explaining the problem. Yes it's my perception that the whole shroud is cocked or leaning rotationally slightly to the right, causing the sight to cant right, causing the rounds I was testing to group 5" to the left at 30 yds. The 5" to the left comparison I am making is in relation to the other three barrels, which, when installed, all shoot center for windage. As to your question regarding the alignment hole in the shroud being wallowed out, no, in fact it was the snuggest of the barrel shrouds to install at that final point where it intercepts that alignment stud screw and frame.

I’ve had similar issues with two of three of my DW’s. The only one that I can have the rear sight reasonably centered is my W12. My 15-1 and 15-2 both need to have the rear sight cranked nearly all the way to the right to hit the point of aim at 25 yards. Anyone know why?

Well, so far, the best I can figure is that the aligning hole on the frame end of the barrel shroud is just slightly misdrilled towards the outer edge of the shroud wall, causing the barrel shroud and thus, the front sight attached to it, to be slightly canted to the right, which in my case, is causing my 8" barrel to group about 5" to the left at about 30 yds.

Does anyone know what the standard height of the Dan Wesson 357's front sight?  I'm considering replacing some of the ramped ones with Partridges.

.280 is what I’ve measured on my very early 15-2 barrel assembly. .130 on the width to match up with the rear sight.

The only way I can think of to fix the misdrilled hole is to fill it and redrill in the right place. Maybe you can find a gunsmith who can do it or perhaps Eric at EWK would take it on. However, the cost might be higher than it is worth. 

You could buy a replacement shroud.frown

That seems to me to be the most expedient solution. At least the shots group. 😲. You could try putting a different roll pin in the hole. That is a $5 item and it may help. If you need one PM me with your address.

If the frame hole was off wouldn't ALL you shrouds be off too, not just this one?

Yes, I don't think it's the frame at all, I think the misdrilled hole is in the 8" shroud.

I do believe that is where I'm at (new shroud), I think the slightly misdrilled one is a great candidate for a scope mount. I've got an email from Gen and we are discussing purchase of a new 8" shroud. My eyes were dilated for an eye exam all afternoon, so I didn't follow up with her today, tomorrow I'll do it.

I thank you very much, but that pin works great holding three other barrel shrouds in perfect alignment, I'm certain that's not the culprit. As I said above, I'm opting for a new 8" shroud and I'll install it, test it with a few loads I'm working on and see if EWK can sell me a Partridge sight for it and the 6" barrel. I'm also experimenting with a Bowen sight, in that he, Mr. Bowen, very kindly sent me a Ruger Blackhawk rear sight to see if it does indeed replace the Dan Wesson rear blade, on the premise that if it does, he'd vouch for his Bowen Target Rear Sight as an also suitable replacement. In return I promised him I would take pics and document the Blackhawk install for him. This was over the phone, what a nice guy he is.

And thank you again for your offer!

Hey one more question; The pin that holds the rear sight in the frame, do we have a size for that for a replacement, or do you guys get by with reusing it once or twice more? I'm going to try this Blackhawk rear sight swap here soon, maybe I should ask Gen if she can send me one or two with that new 8" shroud. You know, just holding the sight in alignment over the sight recess, it's awfully clear that it LOOKS like it would drop right in.  And lastly (ha, right!), being that's a roll pin, do we have a drive it out from right to left, or vice-versa, or just a straight bored hole, either direction is fine?

The 6VH CZ/USA barrel I recently bought has a shroud that is clocked noticeably to the left and I assume is because the hole in the shroud for the pin is off a little. My other barrel shrouds are better aligned on my 15-2. Haven't tried it at the range yet.

Using the proper size dimpled punch the roll pin pushes out to either side and should be  undamaged. If you need one let me know.

Well, okay, I now have an 8" iron sighted shroud and an 8" scoped (Weaver 1-4), and shooting the scoped barrel extensively yesterday, between the glass and the improved trigger (Wolff Springs), this thing is VERY accurate and a joy to shoot. NOW, on to a custom case!
