BC .243 Speer Grand Slam?
Question:
Does anyone out there know the Ballistic Coefficeint for the 100 grain .243 Speer Grand Slam bullet? It’s not listed in my number 11 speer manual and I knoe they have it as it’s now offered in their Nitro Express Ammo. While I’m at it, does anyone out there have any experience using this particular bullet on deer sized? How about other deer killers? This will be out of a 6mm Remington which has about 150fps advantage over the 243 win. I am considering the 85 grain X BT at the high end of the cost per loaded round spectrum and at the low end, the Speer. The Grand Slam is still considered a premium bullet isn’t it? — Sheldon Charron Registered Relocation Specialist Accredited Buyer Representative RE/MAX real estate inc.

The 12th edition of the Speer Reloading Manual lists sectional density at 0.242 and a ballistic coefficient of 0.351 for the 100gr grand slam. the writeup in the front of the book on grand slam bullets said somthing I was supprised at. "Grand Slam bullets in 24 and 25 caliber have a single-alloy core. The jacket walls in the shank are so thick relative to the diameter that the bullet is very tough even without the two-piece core." Until reading that statement I thought all grand slams had a 2 piece core. I am going to use a 243 for some of my hunting this year and have decided on the 100gr Hornady Interlock. The little locking ring in this bullet seems to do more than it should in holding the core in place. I know several people who have been using the 243 for years on deer that have switched to the Hornady Light-Mags since they came out in the 243 with good results. The interlock bullets are cheeper to reload than either the grand slams, X-bullets or Nosler partitions, nad I have found a load my rifle likes. Kevin M Remember the price of the advice
