    Has anyone run into the issue of only being able to load the magazine with 7+1 instead of the 8+1 of the 2 3/4" shells? I get the 8th shell about 1/2 in but it will not go all the way in?

    I have the standard 590, and have had no issues with getting it loaded to 8+1 with in-spec 2 3/4". Are you sure youre not using ammo thats longer than 2 3/4"? I have had ammo before that I thought was, but turned out to be a little longer (but not quite a full 3"), and it prevented me from loading a full 8 in the tube.

    I measured out the shells...they are Sellier and Bellot....and I measure a few shells and they are actually just tad over 2 1/2 inch...I wonder if they installed the incorrect mag spring?
    This is the description on the ammo box:

    12 x 2 3/4 inch gauge
    12 load
    00 buck shot
    MAX DRAM EQ

    The 2 3/4 refers to the length of the shell after firing when the end is opened up. I thought the S&B shells are a little longer then some others.

    My 590 20" holds 8+1 fine with cheap Winchester and Remington shells.

    What 00 buck shot do you recommend that will actually allow me to load 8 in the magazine?

    Yes mine will also hold capacity if I use #6 shot for steel at competitions.

    I use Winchester Ranger 00 Buck. They measure 2.33 Inches and I get 8 +1 in my 590.

    awesome...thanks for all the replies guys! Consensus is leaning toward shell size...so it's off to find some Winchester Ranger 00 Buck! Thanks for the suggestion Jon_R!!!

    It's just odd as a while back I had a 590 Mariner edition and it loaded up fine w/ the Sellior and Bellot shells.....8+1...if memory serves me correctly...but that was many..many moons ago...lol!

    I noticed some shells do vary in size. Or it could be a spring issue? I am thinking shell size...

    I had the loading issue with S&B buckshot, for the record.

    I use Remington Low Recoil 00 buck. I have the LEO version, but they make a civilian boxed version that is, I believe, identical. It patterns very nicely from my 590. 8 pellets, buffered, and reduced recoil.

    I'm pretty sure its the shells...I tried to load 7 in my 930 SPX and it would only allow 6 into the magazine......so definitely shell size and not a mag spring issue....although i went ahead and ordered a Wolf Spring (590 8+1)....at least I have spares....lol!

    You can also buy it from Ammunitiontogo.com; and they don't care if you're a cop or not. I buy lots of ammunition there.

    I have found Hornady TAP PD 00 to be very short. My 590A1 18.5in holds 5+1 and my Remington 870P holds 4+1. I really don't understand all the shotgun mag exts and sidesaddles. IMO they really throw a shotgun balance off. But to each his own.

    Just a quick update...I was able to load 8+1 in my 590A1 w/ Winchester Ranger (RA12005) 12 gauge, 2 3/4", 9 pellets Low recoil, 00 buckshot! I was surprised on how much bigger the Sellier & Bellot shells were!!
    I was also able to load GHOST load 8+1 into my 930SPX...woohoo!!! Thanks for all the replies guys!

    I LOVE Hornady TAP 00 Buck... it's my favorite load... and it's slightly smaller so you can squeeze and extra round ( or two depending) in...

    my local two Dick's had a TON of this early this year after the seasons and it went from like $13 a box of 5 to $7.97 and I stocked up (and just blew a bunch on a 930 SPX Range session, this baby can kick tho, don't let that shorter size fool you) ... and it actually went down to $5.97 one time I went there early summer and I was like "Give me it all" and they had like 4 boxes left , d'oh!

    But again, all things being equal, 5 packs of Hornady TAP 00 Buck would be my desired stock-up shotgun ammo for SHTF/JIC.

    ...I just attempted to load the Winchester Ranger into my Mossberg 500A persuader....and it will take only 7+1 of the Ranger...as well as the Sellier&Bellot....I measured both barrels and they are both 20" in length......if I swap out the 500A mag spring w/ a 590A1 mag spring...will I be able to load 8+1 in my Persuader mag?
