I am looking for info...I have an sp-10 an have been shooting federal loaded rifled slugs. accuracy isn't very good. I am using an improved choke. should I try the full choke?

You need to Cut one of your slug load a part and check the size of it this will tell you what choke to use. You need your slug to be tight in your barrel about .01 to .02 over the size of your bore. Hope this help you
