I can't remember the year the 1000 yd. record was won by a wild cat cartridge called the 7mm x 300 weatherby . It.s in the old Sierra manual. I had one built on a Sako I think in the early 80's and it shot lights out. About the same time Remington came out with the 8mm remington mag. A guy (Layne Simpson) necked it down to 7mm and the 7mm STW was born . The Weatherby was a lot better, but the factory round won out and Weatherby never pursued it. With today's powder and bullets this would be a great round .
