I have a couple of boxes of 12 ga slugs that I have had for 25 years. I had thoughts about shooting them. My question is; all i have is a smooth bore Remington 870 with a modified choke in it, will slugs shoot accurately out of this shotgun? I have not hunted with a shotgun slug since I was like 10 years old so I have literally no experience with shotgun slugs so any help is much appreciated.
