Question!!

headed to WMU 2B for some doe hunting after christmas, what is the best shotgun slug to use?? ive shot sabots before but missed several deer and im usually a trusty shot, just wondered if maybe the flight path wasn as true as i thought, thanks

The best slugs to use are the ones that you site your shotgun in with at the range. You obviously haven't done this or you'd be able to answer your own question. Stay home until you do.......respect the game you hunt.

I have to agree with JK. I sound as though the poster has no put any time in at the range. Otherwise he would have known before missing "several deer", that the "flight path" wasn't accurate. Sounds like he picked up a box the night before, and just headed into the woods

Don't know much about shotgun slugs since I never hunted with one, but it sounds like you are not using a slug gun (rifled barrel). You are not going to get good acceracy from a smooth bore, like said above. Another thing is your scope a shotgun scope? I heard shotguns can mess regular scopes up mabey why its jumping.

Smally Hunter -
 
Two people have asked, and we really can't help you till we know: Are you shooting a rifled barrel slug gun or a smooth bore?
 
It makes a huge difference in the advice you're looking for. 

Check scope mounts,to see if there tight,scope may be the problem,or shooter or slugs,I've played with a lot of slugs,my 1187 love rem.cooper slugs,my little 20 mossberg,loves Fed Preimum Barnes Exspanders,most shotgun have a rather stiff trigger,you my have to get some trigger work,I know I've spent a ton of money on different slugs and shot less than 15 deer with them,but in Ohio,and NY you got to use them.

If you have the $ to upgrade, I'd highly recommend a Nikon Prostaff scope. There is a model made specifically for slug guns. It's what I have on my Mossberg 500 slug gun.

As Tuna said, are your scope mounts tight? If you're a kid, not saying that you can't do it, but it might be a good idea to get a knowledgeable adult to check that out for you. Heck, even if you're not a kid, and you're not familiar with the gun & scope, get a knowledgeable person to check it out for you. Most local gun shops would be glad to do that kind of thing for you - many for a few bucks, some for free.

I'd definitely recommend shooting 2 3/4 inch slugs. If you're shooting 3 in. mags you could be pounding cheaper, improperly mounted scope right out of alignment. I really can't ever see a reason that I'd ever go to 3 in. slugs in my gun. They just hurt, and IMO, do not provide the accuracy that the 2 3/4 in. loads do. As has been suggested, Remington copper solids are decent loads. My gun prefers Lightfield Express. Buy a pack of each till you find what works.

Here's another issue that's very easy to diagnose: are you flinching? With a slug gun, even a slight flinch can send a slug way off target at 100 yards. It took me a LOT of practice and time shooting with my slug gun to cut down on flinching. Next time you go to shoot, have a buddy go with you and load your gun. Once in awhile, have him put in a spent shell without telling you. When you pull the trigger and flinch, you'll both have a good chuckle.

hey thanks for all that, ill def give it all a try , about that scope im sure i can afford one , i work a decent amount for a highschool student and beings that ive been a bum and yet to get my liscense all my money heads straight to hunting and fishing stuff, ill update on results and once again i appreciate the advice

The scope (and ~ or) mounts sound like the culprit to me too.
Does it still have open sights on it too, or just the scope?
If it has open sights you could just take the scope off & see if it'll group better without it.
I'd be willing to bet it just knocked the snot outta your scope & it won't hold zero anymore.
Slug guns really put a wollup on a scope, that's why they make special scopes for shotguns...bet that'd take care of it.

smally,

I shoot a Mossburg 500 w/ a scoped cantilever rifled barrel.  Lightfield Hybreds shoot very well from my gun.  I have tried the Rem copper solids with no luck, as well as the Win sabots.  However, i have friends with the same gun as me and lightfields don't shoot well out of their guns at all.  Slug guns are finicky and you need to do some experimenting with different loads from the bench.  I understand your shoulder will ache and buying boxes of several different types of sabots will be pricey, but like mentioned, you owe it to the game your hunting to be confident in a quick clean kill.

Secondly, your barrel is rifled and you should only be shooting sabots from it if you plan to keep the gun for any length of time.  If you shoot not saboted slugs through a rifled barrel, over time the soft fragments of lead will foul the rifling grooves in the barrel.
 
One last thing, double check your rings and scope mounts like Pork mentioned.  If you can't find any load that will shoot well from your gun I would be the scope can't handle the recoil.  A good shockproof scope is a must for a slug gun.

Good luck and shoot straight!
