if it has the STAR in front of the gauge is is supposed to be ok to shoot steel up to #2 as long as it is not a fixed full choke.

that was Remington's marking

I have worked on 100's of 1100. To me they are one of the best auto loader ever made. The Magnum model was designed to shoot 3 inch 1 7/8 lead load. I opened up the gas port in barrel to shoot light 2 3/4. After I was done with them, you could shoot 1 oz trap load thru them.

There are two different 20 ga 1100. The LT is on a 20 ga frame and is a 2 3/4 inch gun. The other is a 20 ga on a 12 ga frame and is the 3 inch model. The 3 inch model is hard to find.

You have a great gun, it will last another 50 yrs.
.

It’s got the star

Other barrel markings.

You have the small frame gun. It's lighter Then the 3 inch model

Modified choke, shoot it!

It’s a sweet handling gun I’ll tell you that. Small frame, light. I give Bobby 5 shots for his single shot 20 next spring. If he can knock down 3 or more geese then he can have it

He’s still got a couple 410s too so it’s up to him what he wants to use until he can shoot well enough to justify me buying him a benelli (which he talks about on a regular basis)

That’s cool! Do you remember what size you opened the port to in the mag barrel?

the gun my dad bought when I was 11 for me to use , 20ga Rem 1100LT mod choke barrel

the LTs were a dream to carry a little harder to find parts for

as I grew dad added a big 1 1/2 inch thick soft recoil pad and when I bought my own 1100 in 12ga he started using it liking the light recoil

If you are in Edmonton this winter, driving then PM, me and we can line you up with some 20gu shells

Just off hand I think it was a # 47 or 46 drill bit. The gas port on 1100 magnum model is #49 .073

Do not quite me, I have to look it up.

EA is the barrel date code so it was made October of 1980. The "decoder" is the work BLACK POWDER and that is how you date all later Remington's, not by serial number.

There is other non toxic shot other than steel that is supposed to be okay for older guns.
And that one sure is a beauty.

I think it's a # 47 or 48;drill, but have to look it up

I have a mod 1100 12 gauge, vent rib, 3 inch chamber, full choke, 30 inch barrel and a 28 inch barrel mod choke 2 and 3/4 inch chamber. Does anyone know where I can find a 28 inch, mod choke 3 inch chambered barrel?

I shoot steel through both barrels no problem.

Sundance I'd check Brownell's for another barrel or even Scheel's or Cabela's .

Ryan I like Bobby even more now I also have a soft spot for Benelli shotguns !

That Remington shotgun is a good choice also as you know a 20 gauge is more than enough for any game birds add a slug barrel and slugs it's a fantastic brush gun !

its a Light 20, or LT20, I bought one new many years ago. Used it for grouse and rabbits mostly.
The gun never gave me any problems in the many years I owned it.
One thing it ain't tho, is Light, for a 20 ga semi auto it is heavy.
Got tired of lugging it around and sold it.

I didn't see it mentioned, what choke has it got?

Modified choke.

I got an M2 field the year Bobby was born Allen. It was brand new on his first goose hunt at 8 months old. 16 days at camp that year.

Why not just pay a little extra for some Bismuth? Its only 2 3/4 in a 20 gauge so Id rather shoot something more effective than steel anyway. Boss shells are 35 bucks or so for 20 shells.

That is awesome!!

Does he shoot south paw?

I know even if it’s uncomfortable, it’s best to get young shooters to shoot with their dominant eye rather that what “feels right” at the time.
