The 100gn Hornady Interlock is my faviourite bullet in my Ruger Ultralight 20 inch barrel with 1:10 twist. As everyone knows that bullet is discontinued but i have 11 or 12 boxes that I squirreled away. The 100gn Ballistic Tip was too hard in my rifle as velocity at 2772 fps in the 20 inch barrel. The Hornady seems to drop pigs a lot quicker where they ran aways with the Nosler bullet. Bullets of 100gn are the only weight I have ever loaded in mine.
