I used the 150gr SST in my 303 to take a 150 lb buck at 115 yards and got complete penetration. Went in just behind the shoulder (he was quartering away slightly) and punched through the offside shoulder leaving only about a dime sized exit wound. I suspect mv was close to 2650 or so. i just had great luck accuracy-wise in my 308 Model 70 and Browning with the Game Changer, but no way I'd push it in my 257 even though the 100gr Hornady is incredible as far as putting them down. I prefer the 100gr TTSX. I could never get my Weatherby to shoot the 100gr Partition with great accuracy, although my 300 Weatherby likes the 180s and my Browning (Pencil barrel) 308 Safari ONLY likes the 165 partitions. Go figure..

A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
