I used the standard 140gr SP in 6.5x55 to take a mature buck a couple of years ago. Deer was facing me at close range, bullet entered below white patch and exited the back of the neck. Used the PPU Thunder 158gr in 7x57 this year, killed a 3 1/2 yr old buck as he came through the woods chasing a doe. He showed visible signs of being hit after the first shot but stayed on his feet and continued to run through the woods so I continued to shoot. I shot two more times until he made it into the thick stuff. All three shots exited the rib cage, there was no major bones hit other than ribs. Deer ran about 50 yards after first shot. Both shot sub MOA. I would buy again if the need arises.
