3" 20 Gauge Question
 

We're the 20ga offered with 3" chambers? Thanks...

By special order only. "Three-inch" chambers were not a 'standard' chambering but Parker Bros. is known to have made a number of twenty-gauge guns chambered for the three-inch shell. These chambers generally measure 2 7/8" - the practice of chambering a set of barrels 1/8" shorter than the shell they were designed to shoot carried into their "three-inch" guns as well.

Sorry if I was not clear. Question is about 3" 20ga. Reproductions. Were they produced?
Thanks.

My mistake for not paying closer attention to the sub-forum you posted under... sorry.

Yes, I had one and both the 26" barrels and the 28" barrels were for 3" shells.

Dean, are you sure about that? Most 20-ga. 26" guns have 2 3/4" chambers and the 28" guns have 3" chambers.

Frankly Greg, no, I'm not sure about that, I'd have to ask the current owner of the gun.

Maybe he'll pop on here with the answer.

I'm still learning - had previously thought that all the 20 gauge reproductions were 3" chambers...

I have two 20 ga guns, both 26" bbls are 2 3/4". I believe the 2 bbl 20 gauge guns had the 28" bbl chamber3" shells.

Yup, all 28" 20 gauges seem to be bored and marked 3". A 26" 20 gauge with 3" chambers would be a special order gun. All the Repro catalogs can be access in our "album" section.

We all know there have been misprints and mistakes made in some of the Parker Reproduction brochures. Did you happen to notice the 28" 28-ga. chamber length in the brochure above?

Wow- 3 inch 28 gauge!!! Just like the old/original 28 gauge shells I have seen.

But find a gun that's marked that way and we will have something to discuss.

Although the 28” barrels are chambered for 3” shells..it is a bit frustrating that steel is a no-no through the tight chokes that the 28” barrels generally posses considering that is one of the primary occasions for 3" shells :vconfused:

28” - 20ga factory chokes other than M/F appear to be very rare - don't think I've ever happened upon anything other in fact..

With the chrome-moly barrel steel coupled with the chrome lined barrels of the Repros, I wonder if that would hold true on these barrels?






.

I'd be concerned about bridging and the likely result of a bulge / ring

(Edited to add)

Oops..my mistake having not caught what you said in full Dean..Chrome-Moly..has it been confirmed that the barrels are made out of a particular material..4130/4140 as opposed to low carbon steel?

Would that make a difference with respect to bridging and the concern of barrel distortion?

..of course the gripe about the use of steel shot etc. is a 2016 complaint and we certainly cannot whine to much about the lack of forward thinking in the 80's, but it's still annoying :cuss:

3" Chambers
 

Just checked my 20 gauge 2 barrel set. The 26" barrel is 2 3/4" and the 28" barrel is 3". Serial number is DHE 00565.

Those were 2 7/8 inch --

From the introduction of the 28-gauge in North America to WW-II the "standard" 28-gauge paper shell was 2 1/2 inch with a load of 1 3/4 drams of bulk powder pushing 5/8 ounce of shot. The only longer length 28-gauge paper hull offered was 2 7/8 inch. From time to time the companies offered the 2 7/8 inch hull loaded with 2 drams of powder pushing that same 5/8 ounce of shot. In 1932 the progressive burning smokeless powder high velocity 28-gauge loads with 3/4 ounce of shot came out and all the manufacturers put that load up in the 2 7/8 inch shell.

The 2 3/4 inch 28-gauge shell we know began appearing just before WW-II in skeet loads and after the War became the standard for all 28-gauge loads.

Maybe Parker Repro was just ahead of their time --

28" IC/Full Reproduction Chokes
 

[QUOTE=Scot Cardillo;195103] 28” - 20ga factory chokes other than M/F appear to be very rare - don't think I've ever happened upon anything other in fact..


My 20 gauge Repro's 28" barrels came from the factory with IC/Full chokes. Second set are 26" Q1/Q2.

I know of a few 20-gauge 28" that are factory choked Q1/Q2 I own a 20/16 set that both are 28" Q1/Q2.....(-: They are scarce indeed. SXS Ohio

And if anyone would have those rare repro specs, it would be Kenny.

the little 28 ga has gone thru its verious length of shells like all the other gauges for sure.. someday i m gona get me a 28 of some kind....charlie
