Virginia Gun Owners Forum - VGOF

I just bought this brand new at the F'burg gun show this past weekend. I probably could have picked a used one up somewhere A LOT cheaper...but hey, I was kinda in the moment - you know how it is!

I also picked up a couple of boxes of 00 Buck Shot while I was at it.



I also just bought a pistol grip stock for it and should have that installed in a couple of weeks.

I really need to pick one of these up. Looks good. That an extended shell tube? How many does it hold? 7? 8?

I drooled over a Remington 870 synthetic at Cabelas in WV Monday. Only $360. Sorry that I didn't indulge myself, but I already had around $400 of ammo in the cart. They had a good deal on .223 and powder.

It holds 6+1 (2-3/4 and 3" shells). I can't wait to get it out and put some lead through it.

Only 6, hmm, memory is off. I thought they held 6 without the extension. Oh, well.
If 7 isn't enough, learn to shoot better, right?

Hmm... I just looked it up - the one I have - the "Persuader", as it's affectionately known - model 50577 - is an 8-shot (7+1). When I try to get that 8th round in there, it's about 1/4-inch too long. Not gonna play with it any more tonight. Need to get it out on the range and see how it likes to hunt clay pigeons

Nice shotgun. What length shells are you using? the 7+1 spec should be for 2 3/4 inch shells, 3 inch would be 6+1.

That's the 500A Persuader I was looking for when I bought my 5+1 model, but the price was right so no complaints here. Good score

I have 2-3/4 Sellier and Bellot 00 Buckshot in there and it's only holding 6+1.

What's the barrel length?. If it's 18.5", then that would be correct.

Weird, mine is an older 500A but with the plug removed I'm pretty sure it's 4+1 for 3 inch and 5+1 for 2 3/4. Maybe Mossberg changed the specs and didn't update their website. Or, maybe they had to plug it to 6+1 to meet some silly state law in one of the communistic states. I'd check for a plug.

So, I bought some Remington 2-3/4" shotshells today and it seems that the 00 Buck shells are about 1/4" longer, even though they're both marked as 2-3/4" shells.

So, long story short - I can get 7+1 into the Mossberg 500 with the Remington shells, but only 6+1 with the S&B.

The S&B are imports, must be cause they are metric.

It seems to me, that I remember reading somewhere, that shotgun shells are measured in the uncrimped position. I just went and got a couple of old shotgun shells (unfired) out of my gun cabinet. The "2 3/4" Winchester actually measures 2 1/4". The "3" (marked) Remington actually measures 2 1/2". Upon firing they open up to 2 3/4 and 3 inch.

That's why a 3" shell will chamber in a 2 3/4" chamber, but the crimp, will extend past the end of the chamber, forcing the shot charge, and wads to compress as they go through that area, creating a dangerous pressure spike. I know a lot of people who do it, but it's sure not a good idea.

It's may be that the European shell is measured in the crimped position. What they call a 2 3/4 inch shell is actually what we would call a 3". I'd be careful what gun I shot them in. In your case it won't matter too much, since the Mossberg has chambers cut for 3", but it might for others.

That makes sense - look at the picture above. The Winchester shell is crimped closed at the end. The S&B shell has more of a "cap" on the end with a rolled end to hold that cap on. So, the S&B shell has a much smaller crimp area that opens up versus the Winchester shell.

I'll go blow a couple of them up and take some measurements.

Have you tried cycling the Aguilla mini slug/bucksot thru it yet? The only pump that I have that will reliably cycle them is a Winnie 1300 but don't have a Mossy to try.
