The barrels are "Acciaio Speciale Al Cromo Molibdeno". The last set Briley chokes were installed and the bores were sized the same with no additional charge. I never did ask any questions about chrome bores. I thought this was a type of steel only. I have been wrong before(O..so many times). I have given some thought of equalizing the bore on the heavier gun if it isn't chrome lined. Then again I am open to other thoughts even adding weight to the lighter gun. I will admit Stan has the most practical approach...if all else fails.

If the two guns differed in barrel length, would you be looking for a solution to make them identical?

eightbore,
If the lengths were different I wouldn't be attempting to make them a composed pair. I do have a few similar Beretta SxS shotguns but non like the 411E 16 gauge pair that I felt were close enough to make a composed pair with. Hunting is over now and this effort will fill a little time before Summer is upon us again.

Hi Rocketman,
Happy New Year. I thought I would bring this back up in hope that you may have run the numbers.

Ron,
That 2 oz in the barrels is knawing at me. I'd measure the bores and walls to figure out where it is.

Chuck,
The bore readings are .665 and .669. The weight of the barrels are 1.80 kg. the lighter set have a .678 bore in both and a barrel weight of 1.55 kg. when the bores were proofed. the light barrel bores were .677 and .669 before Briley work was done. Hope that helps.

While it is possible you can feel the difference, I suggest you consider a different objective. That objective is to give both guns the same feel in terms of balance and momentum. Look at adding or subtracting to the guns to give them equivalent feel.

Perfectly Matched guns are darling but in reality rare and I have seen more than one pair of guns that were slightly off. What matters is they handle identically, not that they are identical

old colonel,
Rocketman was going to run some numbers to help answer that question. I don't feel the difference but the thought of making them closer to the same weight was just a thought since hunting season has closed and the weather is cold.

Ron, I had a pair of British guns (A&N, made by Webley & Scott) that were less than an ounce apart. Have had a couple Spanish pairs, one of which was closer to 2 ounces apart. As Rocketman indicates, I could not tell--without looking at the number on the gun--whether I had AyA #1 or #2 in my hands.

From the difference in bore diameters on your guns, post-Briley work, looks like they might be pretty close in weight if you were to have Briley bore out the tighter pair to match the lighter/backbored pair.
