28 ga Repro
 

New to new me a nice straight grip two trigger 28 with 26” imp/mod barrels. It is a 800 serial number gun but was a bit surprised when I checked chokes, right .004 and left .018.
No signs of having barrel work that I can tell, this fall in normal range for chokes?

I love the combination just curious. Thanks

That sounds more like Q1 & Q2 chokes to me but I’ve heard of other Repro chokes that didn’t measure to correspond with the choke stamps on the flats.

As you go to smaller gauge the amount of constriction needed for a particular choke designation becomes less. For example in 12 skeet is .005, in 28 .003.Mod in 12 is .025, in 28 .012. This table was found on Google and attributed to an obscure organization called the PGCA.
When i first found this i checked a .410 Stevens ''turkey '' gun made to use TSS and to my suprise its ultra full choke was .017.
According to that table your gun is skeet and improved mod. a great upland gun or it is as stated imp/mod.

Kathy’s 28 gauge Repro’s chokes measure Rt. .005” and Lt. .007”…. FWIW

For comparison purposes my 28ga. DHE factory stamped IC/M chokes measure .006/.016. I am the original owner having purchased the gun new from Cape Outfitters at the closeout in 1995. The chokes are un-touched original.

My 26", marked IC & Mod, measures .011" and .020". That sure looks like Mod & Full to me.

Chokes
 

The charts I have reviewed mine is Skeet/ imp. Mod.

I can't comment on a the reproduction chokes but I learned over many years of shooting 28 gauge guns that you are much better off ballistically with tighter chokes.

Damn! He is good too

Edgar, yours are proper mod and full. However, 28 gauge Repro fulls are usually .039, twice a normal full.
