My brother has 2-.270s, a Remington and a Ruger...Both are sighted in 2 inches high at 100 with the Federal Premium Sierra GameKing SPBT 130gr bullet...Both guns shoot into 1 1/2 to 1 1/4 inches...Between them they have killed about 100 deer and a black bear...I know it's not a flat based bullet, but it works...
