I just got a slug barrel for my 500. Its the 24" ported w/scope combo. The problem I have is that I only have access to a 25 yard range. I was thinking of sighting it in 1 and a half inch high at 25. I will be shooting rem buckhammers. Any ideas? Thanks!
Need help sighting in mossberg 500 slub barrel....

well the best way to sight in a slub barrel is to place a glob of silly putty in the end of the barrel, then blow really hard from the other end, where the silly putty lands is where you need to adjust your cross hairs. 
To sight in your slug barrel (I'm assuming with a scope, that's at least aligned with the bore or roughly bore sighted) Take 3 shots at the 25yd target, see where they hit, then adjust the scope to change point of impact to the center of the target, then take 3 more shots, if all is well, you should be done.
As far as compensating for yardage, what distance do you want to be sighted in for, are you hunting thick woods, or fields? If you are going to use the gun for hunting, you should really shoot it at distances similar to what u will see when hunting, it's the only definitive way to see where it will hit. I am also guessing that if you are asking this question, you could use the practice anyway. Find a better range.

Mossy Rifled Bbls...
are awesome!
Mata 777--I just concluded working 2 weekends and W-T-F of last week @ my gun club, on the 50-yd range, helping people sight in and practice with their shotguns and slugs.
We had a plywood "running deer"--which mostly just teaches people to not shoot @ a running deer--but they could shoot @ Plywood Bambi standing still and we could coach them, or we had targets @ 70 yd or for people with REAL problems, 20 yds.
So I'm currently VERY experienced with a variety of shotgun bbls, rifled and non, and a variety of shotgun slugs, the fancy Brenneke or Rottweils, or common Winchester lead pumpkins, and several brands of sabots. One shooter even brought Remington paper-shell slugs, would you believe! (How long has it been since those were made?)
Very experienced, yes indeed--TOO DARN experienced in one case--shot a slug gun for one customer to see if the problem was the gun or the shooter, and got kissed soundly in the eyebrow w/his 'scope. (Short stock, long 'scope, short eye relief, my long arms--You do the math.) BTW, the gun shot fine; shooter needed more practice.
For your Mossy 500 Rifled w/scope, you will probably want saboted bullets, not slugs. The Hornady sabots seem to work consistently the best with most rifled shotgun bbls. I know they are pricey--you can work some overtime and buy a couple boxes of Hornady sabots, but you can't buy a down deer; you have to shoot it yourself.
I have a Mossy 500 myself; like the model very much. (Mine is my goose gun.)
Now, as to sighting, you can roughly sight it with about 3 shots @ 25yd, however as Moo JPG 2 pointed out, you need to practice with it @ the range at which you expect to be dealing with Mr. Bambi. That means burning up a couple of boxes, at least, of those expen$ive darn slugs.
If the best range you can get is 50 yd, set the POI abt. 3" above the POA, and you should be lethal to 100 yd and beyond. But PRACTICE!!
Oh, well, if you were going to Africa to hunt, you'd be practicing with .416 Rigbys or .375 H&H's, at $3 or $4 per boom.

Sight 2" LOW at 25 yards.
Due to the height over bore of the scope and the rather extreme drop of a slug, sight a rifled slug (non-sabot) to impact 2 inches low at 25 yards. Then move to the 50 yard line and you'll find yourslef needing very little adjustment to get dialed in there.
Just be prepared to do a lot of cranking on the scope turrets at the 25 line. A click value of 1/4" at 100 yards is only going to move you 1/16" at 25. In other words, 16 clicks to an inch. Eight clicks at the 50 line.
I don't use sabots, so I've got no idea what the trajectory is for them. My slug gun is a smoothbore 500 with reciever mounted scope and Winchester 2 3/4 rifled slugs.
If your barrel has rifling in it, you should use sabot slugs, as Smokey Joe said.

Thanks for all the replies. The shells I have in stock are remington buckhammers which are for use in a rifled barrel or chokes according to the box. Sorry if I got you guys confused by the term slug (I shoot foster type rifled winchester slugs in my smooth barrel).
