A good buy at $5 per box out the door at a gun show over the weekend.
Kent Gamebore 65mm (2-1/2")
Traditional Game 20-gauge shells with fiber wads and 28 grams (1-ounce) of bare #7 shot. That's right, no plastic shotcup. These British #7 pellets are very slightly larger than our #7-1/2's. Box printing states they're made for short chambered 20's that are proofed for 3 tons service pressure. That's a little shy of 9000 psi and well under our US SAAMI 20-gauge pressure max.
First pic shows the comparison with a RST 2-1/2" shell on the left.
