I have great confidence in Orlen, but will certainly consult with Eyster if need be. Thanks for mentioning him.

I may end up having to accomplish it with "screw-ins". I know that can be done by the use of the eccentric chokes mentioned by Gil.

Will definitely report on what happens.

I second Eyster. A couple of months ago in an English sporting magazine a guy talked about having a pair of 28 bore guns made up for shooting high birds. Bought a pair of Perazzi 28 bores with the tightest chokes Perazzi could put in the barrels. Sent it over here to Eyster to regulate.
Went on to say how well he did at getting the barrels to pattern.
Can you tell who the maker was of your 410?

What kind of shotgun is it Stan? Chrome lined suggests recent manufacture. If so, maybe the manufacturer would make it right. Considering you only have .008" of constriction to work with, I seriously doubt if you'd get to where you want to be by laterally honing the chokes, especially in a chrome lined bore.

Nobody mentioned the thought of weighing the cost of eccentric screw in chokes versus the cost of a strip and relay of the ribs, with a slight spreading of the barrels to regulate POI. Yours must be crossing at around 15 yards.

At 15 yards, it will still crossfire, just half as much.

Huh?

It is the Dickinson, with 30" barrels. Funny thing is, I shot doves with it for two seasons before I put up my grease plate and began patterning my guns. I had no trouble taking a limit of doves with it, with pretty fair averages each time ........ well over 50%, but could recall a few shots each time that I couldn't figure out why I missed. Now I know why. There's just not much meat on the "skinny side" of each barrel's pattern.

I really like the gun, disappointed as I am with the regulation. Before anybody kicks Turkish guns too hard, let me point out that my $489 Yildiz S x S .410 is regulated as perfectly as any gun I have ever patterned. And, when you consider that Beretta has an 8" allowance for mis-regulation, there's not much chance of getting this done by Dickinson I wouldn't think. I wish I could get back to the old thread that ChuckH created detailing how much he moved his patterns by honing the muzzle. As I recall, it was significant.

Don't change a thing Stan. That cross shooting provides you with the built in lead that must be what's resulting in your success with the .410...Geo

Maybe you were just flinching

Maybe a 90 degree cross wind came through from the west just as I touched off the right barrel, then reversed and came through from the east as I shot the left ........ and did the exact same thing several times with different loads. Or, maybe the fact that the barrels are not regulated for the proper distance caused it. I dunno. What's the most likely scenario?

Some more clues. I patterned three .410 doubles that day ........... a Verona O/U, the Dickinson, and the Yildiz. Out of the three I only flinched with the Dickinson. Idinat strange?

Stan, I think you are likely correct on your POI, but as mentioned, one can easily flinch on a single shot. May I suggest you shoot a 4-5 shot group at your given yardage? That's what Eyster does to establish POI. Look for densest area of the multiple shot group and that's POI.
