28 gauge slugs...???...

I have 2 or 3..They were made by Remington in green paper casings back in the 40s or 50s...

As far as CURRENT ( or even recent) manufacture of 28 gauge slugs, I have never seen them anywhere, nor HEARD of any, including Canadian and European manufacture...

I'm not saying they do not exist, but I would be REAL surprised if they do...If so they would an expensive purchase from some obscure European source...

Take the above advice and get your boy a 20 gauge if he wants to hunt deer with a shotgun..There is an excellent selection of 20 gauge deer slugs/bullets available out there..
