Title: Mossberg SA-28 Cycling Issue
Post by: deltabowhunter on March 26, 2023, 03:34:34 PM
I have an SA-28 Bantam that will not cycle Apex 9.5's. It will cycle Federal game loads and AA factory loads just fine. Has anybody else ran into this issue?

I have not had this problem but a friend had this problem.  The Hulls were just a hair too long.  He talked to Brice Hensley at Foxtrot and went that way.

Have a good one, Bo

My wife's SA-28 will not cycle the Foxtrot shells & it's due to the chamber being a little undersized. Apex cycle fine. From what I understand some of the Turkish guns have this issue. I use Foxtrot in other guns.

Yeah, you're right. I am shooting Foxtrot out of my Charles Daly 28 gauge Semi, and they cycle well for me.

I have the SA28 bantam and the SA28 tactical turkey and both cycle Apex 9.5's just fine.  I've shot cheap game loads, Foxtrot, Apex, hand loads, Rogue, and Viper and all have cycled just fine.

Let me clarify my statement a bit more... it will cycle the spent shell out fine, but it does not load the next shell from the magazine. I can manually cycle the bolt slow or fast, and it works, but it doesn't work when shooting. Apex said they haven't heard of that issue, but would be willing to refund me for the ammo.

We have a trip to Texas this weekend. I guess I'm going to ghost load one under the bolt for my wife just in case she needs a follow up shot.

I actually just took mine to the range and sure enough it shoots the first shell fine and the other 2 did not even come out of the mag tube.  Apex and hand loads both did it.  I posted earlier that mine didn't have any problems but after I thought about it I've only ever loaded one at a time.  This is wonderful 8 days before the opener.   What would keep it from not pulling the next shell out of the tube?  If I hand racked it, it worked

I contacted Mossberg today via email. They first said the shell was too light of a load. When I pointed out it was a 1 3/8oz load they said it was an ammo issue not a gun issue. Very poor customer service.

I just ran a couple of tests. If I put a target load in the chamber and Apex in the magazine it cycles fine on first shot. I think the issue is that the Apex loads are so hot that they're cycling the bolt too fast and the second shell doesn't have time to load.

I tested that it works, so what I plan to do for this Saturday is load one in the chamber and ghost load one under the bolt. That way, you can get two shots off before manual intervention is required. Not ideal, but in Texas, you better be ready for more than one turkey to show up at once.

What are you planning on doing after Saturday?  I was going to call Mossberg in the morning but it doesn't sound like I'm going to like their response

Post by: deltabowhunter on March 30, 2023, 10:26:42 PM
Well, we have our youth season the next weekend and then regular season. I'm going to continue the necessary load process for two shots and then take it to a gunsmith.

If Mossberg gives you a different answer, I would love to know what their solution is to the problem.

I went back to the range today and Apex did it again, but Viper, Rob Roberts, and hand loads all seemed to work.
I called Mossberg on the way home and all they could tell me was to send it in, and there was a 6-8 week turnaround.

I am also curious, because I have a SA28 turkey on the way.. how many rounds have been shot through your guns? Just wondering if they need a little breaking in??
Title: Re: Mossberg SA-28 Cycling Issue
Post by: FL-Boss on April 02, 2023, 10:00:44 PM
My brand-new SA-28 has had zero issues. A handful of high brass shells to get the red dot on paper.. then about 12 rounds of Apex #9 and #9.5 to test different chokes. No problems...

Mine has somewhere around 300 rounds through it.

Anyone have an update on this. Mine is doing the same thing. It cycles federal top gun flawless but apex and foxtrot won't cycle. Kicks spent hull out but the others won't even drop out of the magazine tube. If I single fire the apex and foxtrot it won't lock the bolt open but the lighter load will work every time

I bought mine unfixed in the box. I took it home and disassembled it and cleaned every part. I then polished every surface I could with a scotch brute pad. Sprayed the parts down and reassembled. The cosmoline in this gun was gross. Small chunks were cleaned out. The gun runs smooth as silk. I also shoot a few rounds of sporting clays before the season as well. The wife's new one was just as caked , but the initial cleaning took care of the issue. This is a $500 semi auto shotgun, remember, you pay for materials and machining. The better the materials and tighter the tolerances, the price goes up. This is a great gun for the money.  :z-twocents: Z

I ended up just trading in my bantam.  It wouldn't cycle anything except target loads.  My SA28 tactical turkey model functions flawlessly though (so far).

My sa-28 turkey is the same way. Will eject but not chamber the next round. I have a 20ga sa-459 doing the same and both are using the same powder. Tried a diff powder load in the 20 and runs fine. I'm guessing the slower powder is still burning while trying to eject the hull simultaneously and its throwing it out of time.
Eta I've tried the same load in inertia and recoil operated guns and they ran it fine. Gas systems seem to be a no go

When the cycling issue happens, are you shooting from the shoulder or some type of lead sled? Or, even the hip?
Title: Re: Mossberg SA-28 Cycling Issue
Post by: turkey_slayer on May 05, 2023, 10:28:53 AM
Shoulder while sitting against tree. I use bags on the bench but only loaded 1 at a time. Will test that after the season. Just to clarify, the shells in the tube stay in the tube after ejecting the fired hull. I can rack the bolt and it'll load the next one. The brass is dented and rim will peel from the extractor. Neither are excessive but the same load shot in any other non gas gun come out fine. That's why I think the slow burning powder may be still burning while the gun is  going through the ejection/loading process or it's overloading the gas system. Could be totally wrong. I didn't notice it till I killed the first turkey and it's done it on every bird since. Thankfully haven't needed a second shot yet.

I just got bit too, my pride came back to bite me. The new primed hulls I loaded are about 1/8" longer and are not cycling real well. I had to manually slam the bolt ahead to get a second shot off the other day. I either need to get a case trimmer or get a pump, lol. I am dreading cutting open these shells. Good luck and God Bless.

Anybody have any update to this?  I took both of my SA28 tactical turkey guns to the range with me yesterday when messing with some other guns.  1 ran apex just fine.  The other one shot the first shell, then didn't bring up the next one.  Hand racked it, then ran 3 through it just fine.  Thinking about trading one of mine in for something else if there's no fix for this.  Mossberg blames it on the shells, but what kind of shells do they expect to be shot out of a "tactical turkey" model?  I don't have the $ to just keep blowing through tss to see if it's going to keep happening.

I discovered that mine does it on all steel duck loads as well except for 7/8oz Boss Shotshells

Basically, anything that isn't a 7/8oz or 1oz load it won't load from the magazine.

The manual says it works best with those size loads, but making a gun primarily marketed to turkey hunters shooting heavier TSS loads is pretty sorry of Mossberg, considering they know it won't cycle.

I fixed mine by sending it to CRums and had him tap the ports for 6-32 screws. Now I can adjust the port size by drilling out set screws. Pretty much ended up blocking the ports off by 60% when tuned perfectly. I tuned by loading only 1 shell at a time. I started off undergassed and kept increasing port size till the bolt locked back on empty. Then went to 3 shells to verify cycling. Increased ports slightly as it was barely ejecting, but ejecting never the less, till I started seeing extractor marks and dropped back down to the next lower drill bit #. Runs like a machine now and recoil is noticeably less.

Sent in the trigger group to work on also and dropped a MCarbo spring in. Down to about 3.5lbs now. He done excellent work

If it was me, I would order a new Wolf or similar recoil spring/mag spring.
While changing springs I also get a trigger spring, M-Carbo.

I never heard of any updates.  I had 3 and sold them all due to cycling problems.  Seems like they're hit or miss.  For every 1 I hear about that has cycling problems, someone else says theirs runs perfect.   I really loved that gun, and hated to let them all go, but mine wouldn't cycle anything and I tried just about every TSS available.  I had one that was fine for over a year and a lot of range time, then just mysteriously quit cycling.   Very disappointing, but I don't have the time, money, or patience to deal with faulty guns.  All of mine were meticulously taken care of, so I don't know what the issue is other than I believe them to be over gassed with TSS.   They all shot fine with target loads.  The only fix I've heard was posted earlier in this thread, and that is to have the gas ports manipulated.

I shot mine yesterday to confirm POA/POI and it continues to cycle. Hopefully that's not a temporary thing. (https://uploads.tapatalk-cdn.com/20240402/4a292674fdb741b7580ccfbc5bdbe897.jpg)

I was having cycling issues with mine but I switched from H110 to Lil Gun in my handloads and have yet to have an issue? Might be coincident IDK but I am getting to where I am starting to trust it and hope that it doesn't fail when and if I ever need it.

How do I get ahold of CRums? I need to have mine tapped so that I can adjust the gas to get it to cycle properly.

It's not the gun most likely. The gas ports weren't designed for the powders we shoot. Nature of the beast. That's why field loads cycle just fine
