I was sent these prototype 12ga Shotgun Shell holders to evaluate without graphics on the package or instruction manual. They’re polymer and fit 12ga shell securely enough (I didn’t have any 20ga shells to test). They attach to the side of your shotgun receiver using 3M-style adhesive pads, though I’m not sure how well the pads will stay on long term if exposed to gun cleaning solvents.
I gave my contact at the Shooting Product Club some feedback. The product works but is probably better suited for airsoft than reel steel. I’m not sure who the market is for in real firearms? Sure, it’s a budget way to attach a quick load set shells to your shotgun but I personally don’t like the idea of exposed shells that could get snagged.
Trap and clay shooters have round restrictions when competing. Bird hunters are often restricted to 2 round in their gun so perhaps them? Or maybe 3-Gun users maybe who want just an extra backup holder? Looking at Amazon, I see they’re now on sale and quite affordable with 2 packs going for under $10. https://amzn.to/3ciJZEg
