Just ordered a Mossberg SA-20 last night online so I don't even have it in my possession yet.
But I just had my 1st OH NO moment with this gun.
I am planning on using this gun for Skeet. I no longer hunt.
I just learned the recommended light load for it is 15/16 oz.
That is way above what I wanted to shoot in a 20 ga. gas auto.
I was wanting to eventually shoot 3/4 oz. in this after a break in period.
7/8 oz.would be my max. It never occurred to me a 20 ga. gas auto advertised as all purpose required such a heavy load.
I have shot much lighter reliably through a 20 ga. Benelli Montefeltro.
Should I be worried?
Can this gun be modified to shoot light loads or does it even need modification after break in?
Do I need to get a for sale ad ready for this gun?

For 20 gauge, 7/8 oz. to 1-1/4 oz.

I don't know why they say 15/16 very odd, but it will cycle standard 7/8 target loads just fine.

I have not had any trouble with my SA-20, no matter what ammo I have fed it. In the initial break in, I ran four boxes of 3 inch #6 heavy game loads through it. After that I have been using whatever I have laying around. I have even used some of the Federal cheap target loads from Walmart. I did have a few weak ejections with those, but they did cycle fine.

Regards,
Joe

I will break it in with 1 oz. Rio's and see if I can eventually coax it down to 3/4 oz.
I can't use reloads for the warranty period anyway.
Academy has those Monarch 7/8oz. #8 1300 f.p.s. 20ga. loads for $4.99 a box.
That should do the trick.

Sure you can use reloads.

The SA-20 is anything but new. It is made by Armsan, and whether Mossberg or TriStar or Armsan . . . same, identical barreled action.

Sorry to disappoint you, but the chances of needing break-in is about zero. Armsan, who actually makes the guns, has always said 7/8 oz. That Mossberg / Tristar etc. cannot do a proper cut and paste is nothing to be concerned with.

No I am not disappointed at all. I am excited. This is actually my 1st NIB shotgun purchase in 10 years. Several used in between but none new. The comment about not using reloads was in reference to the owners manual you linked to saying using reloads voids the warranty.
Now how they would know if I was using reloads is another matter.

It is no more possible for a proper handload to damage a shotgun than it is for a proper factory load to damage a shotgun. That statement doesn't come remotely close to passing the sniff test.

It is reasonable to state that a shotgun warranty does not cover damage caused by improper ammunition. Whether that improper ammunition is deemed "factory" or not has nothing to do with it.

I shoot factory 7/8oz loads just fine. Love my SA-20. I also enjoy the Academy Monarchs in both 12 & 20.

I agree with JOESPUD27, I have been buying the Monarch light dove loads from Academy for a while now. I get the 7/8 oz, 1300 FPS #8's. They work great in my SA-20 and you never feel any recoil at all. At $4.99 a box you can't go wrong.

Regards,
Joe

I think I tried a few that I loaded up for my old LC Smith. As I recall it cycled fine. It actually throws 7/8 oz loads pretty dang far. Far enough I was concerned heavy duck loads would damage it. But it’s relegated to light load duty now anyway because the boy is not bigger than me and shoots a 12 at ducks. And my experience matches what Randy said. We cleaned it good when we got it home and went to the range with your basic 20 ga 7/8 load. I would avoid the cheap Winchester Universal loads but then I do that regardless of the gun or gauge.

This was a concern of mine. I recently opened the box of the first shotgun I ever bough, the SA-20.

I went to buy some ammo. I read good things about Fiochi, so I bought a few boxes.

I got home and reading the manual I saw the 15/16 min...so I went back to the shop and beg them to take the ammo back because it was 7/8 oz, which they kindly did. I started looking for 15/16 which of course I could not find in any of the other 10 stores I went. Then I looked for 1 oz...and found none...by then I was like why would anyone make a shotgun that shoots anything but the most available ammo?

Eventually a local store had some 1oz online which I'm still waiting on.
One of the shops recommended high brass 7/8 to prevent ejection issues, so I bought a box too.

I figured the SA 20 would probably shoot 7/8 but I figured follow the manual first. That's what you do when you don't know much, just follow the book.

I'm going to try a bunch of different 20ga ammo in 2 3/4 & 3" to see what I like. The gun looks to my liking in black synthetic but I thing I'm going to wrap the stock and the forend in camo wrapping tape.

Update:
I have been shooting Skeet with this gun throughout most of the Summer.
I started with Herters 7/8oz. factory loads from Cabela's. No issues and they ejected into Broward county.
I started reloading 20 ga. again but down to 24 gram. Again no FTE. Next reloading session I plan on reloading a box down to 3/4 oz using a 7/8 oz.wad and fast load data from Alliant's loaders guide using the Unique powder I have on hand.
So far this gun has been flawless.

Hello,

I know I'm resurrecting an old thread, but I am looking for an answer to this very question. I am interested in the SA-20, but only if it will eject/feed 3/4 oz loads.

Did you end up giving it a try? If so, what velocity were your loads, and did they cycle the gun?

Thank You!

My wife's youth model SA-20 has functioned flawlessly with 1200 fps 3/4 oz. loads. Never had a problem with it or my SA-28 in two years and roughly 3K rounds through them.

Mine won't, nor are they designed to, or claimed to.

My wife’s shoots 3/4 ounce hand loads flawlessly, yours may or may not . After breaking it in with several boxes and a good clean you will know

Thank you very much for your replies!

They will only be used to get my daughter started, and we can move up to 7/8 oz loads. It would be nice, but I can always eject them for her if need be, she'll only be shooting one at a time for quite some time.

2 our of 3 works for me, I'll take my chances, it really seems to be a nice gun.
