Golden Saber is good stuff, but you do see core/jacket separations with them pretty frequently. Remington does make a Bonded Golden Saber, but they aren't terribly easy to find.
At last year's SHOT show, Remington had promo materials for the Golden Saber "Black Belt," which looked like a Golden Saber with a delrin band around the bullet to limit expansion and core/jacket separation. I never have seen anything else about it, so I don't know if it was ever successfully brought to market.
FWIW, there are several loads out there that are as good, and in some cases, better. The Speer Gold Dot, Winchester Ranger Bonded, Winchester PDX1, and Federal Tactical Bonded are all as good or better, and are all bonded bullets.
Oh, and to answer a previous question, the Federal HST is not bonded. The Federal Tactical Bonded is like a bonded HST... Sort of.
