Depends on what the barrel is choked.
Can you Yes, should you NO. a full choke should not be used to shoot slugs.
yes for a shotgun you need a rifle barrel DO NOT shoot slugs if you have a poly-choke!
n You will need to contact Mossberg to find out for sure.
Yes. Accuracy may be better in an IC choked barrel, but they are safe to shoot.
Yes- but accuracy with slugs in any double barreled shotgun is not the best- the lines of the barrels converge. Imagine a very large X. Right barrel will shoot somewhat to the left, left barrel to the right.
Yes, but an easier method would be to sprinkle salt onto the slugs.
with the wingmaster barrel you can only shoot lead, but if you change the barrel to a slugster you can shoot slugs and buckshot, they also have a barrel for steel shot to.
Whatever the correct ammunition is for that gauge. Sabot-loaded slugs tend to be somewhat more accurate than so-called "rifled" slugs in most guns.
No.
You will need to change barrel's, a accu choke is not on a slug barrel.
Shooting rifled slugs is the ONLY way to shoot thru a smoothbore for deer. If you shoot sabot slugs thru a smoothbore, it will not spin and therefore not be accurate. For accuracy, the slug must spin out of the barrel. Either shoot a rifled slug thru a smooth barrel, or shoot a saboted slug thru a rifled barrel.
