10 gauge 2 7/8"ammo and BRI 12 gauge slug

I have a box of Remington 10 Gauge ammo. It is 2 7/8 inches and 4 shot, It is in a 20 round box. on the end of the box it says 4-3/4 Dr.EQ. PWDR. 1 5/8 OZ Shot then SP10-4. I bought this box new when I was in 8th grade the shell is not crimped instead it has a paper plug on the end of it. I know it is safe to shoot and it shoots well out of my h&r 10 gauge mag with a 36" bbl. Has any one sen any of this ammo any-where?

Next-I found 4 sluggs in the back of my gun cabnet they say BRI and are 3" mag sluggs any info on this?

Thanks-Rob
