Thanks for the replys. I have shot a 52gr hollow point and 55 gr with excelent results. I needed to go to the 60 grain partition as I needed a tough bullet for my daughter to hunt with. I have tried Imr 4895, Varget and RL-15 and cant get under 4" at 100yd. With the 52 and 55 grain I've chased animals for hours not wanting a hit animal to get away. I guess what I need to know is the twist, barrell length req. to stabilize the bullet. Thanks and any other info appreciated. John
