The second most accurate load I had for the 350 Rem was with 250 grain SPEER bullets (most accurate was with Interlocks):
350 RM, Remington 600, 250 grain SPEER, 9 1/2M, 56 grains IMR4320, 0.66 MOA
In my 256 Win Mag the most accurate load was factory Winchester, alas I don't have any anymore. But the following was one of the two most accurate hand loads. It is devastating on cotton tails.
256 Win, Winchester 92, 75 SPEER, 16 grains IMR4227 0.700, 1.13 MOA (group sizes averaged .7" at 59 yards)
My cousin likes the 170 Grain SPEER bullets in his 8x57 - he says it is the most accurate load he's tried. I believe he said that was with IMR4064.
