Suffolk Custom Reloads Co. 24 Grissom Way Hauppauge, NY 11788

Anyone ever heard of this company? I found a 50 rd. box of their 9mm reloads I had squirreled away, must have bought them at a local gun show back in the early 1980's when I had a 9mm pistol. Never shot any of them. Tried looking up the Co. with no luck, so they must have gone by the wayside. The box is green with a bullseye printed on it. If anyone has ever used this brand ammo was it any good? Most shell ends are marked TZ 78, with a few marked TZ 79, one or two marked TZ 80 and  a couple marked TZ 77 Ends of box are marked:9mm Luger 100gr. JRN HORNADY Bullet

Suffolk County, NY wouldn't be a friendly location for an ammo manufacturer.  I'd bet that they're long gone.
