75 gr. bullet loads for 257 WBY.?

[albie1]

I have started to work up a Varmit load of 75 gr. bullets for my 257.Anyone have any ,good or bad info for this size bullet? Also, any really accurate loads?

I have not shot any 75g but have shot some 85g nosler silver tips.Best load so far 69.5 g 4350 powder, 3756 f/s and 3/4 in  groups. I am interested in the 75g though.Keep us posted on what you come up with.

IMO you are definately on the right track with H4350 - 65 grains with a 75 gr. Vmax should give you over 3700 fps with moderate  pressures - a definate red mist mixture.

Sierra shows 68.3grs. IMR-4350 @ 3800fps as it's accuracy load, 69.4grs.@ 3900fps as it's hunting load, w/ a Max. load of 70.5grs.

...another load you might find interesting is the 87gr. Speer TNT's, they show better retained velocity @ 500-600yds, w/ less drop...
