Use 25-06 cases necked up and you probable will not have to turn cases and fool with doughnuts, at least my buddy did not have to. He shot a lot of 120s with H4831. For a GREAT 130 gr bullet the Nosler Accubond is it. I use it in my 27 3/4" 9 twist #5 Shilen CM barrel 264 Win mag and even pushing it 3350 fps even at 25 yards it will hold together through both shoulders of a deer with an exit of about quarter size. It does the same thing at a touch over 500 yards. It likes to jump 20 thousands in my rifle.
