A few.
1) Sierra 75 grain HP, 44 grains of IMR 4064, WW +P brass or Remington brass, Fed 210M
2) As above, but 41 grains of 4064 and 90 grain Sierra BTHP
3) 100 grain ballistic tip or partition, WW +P or Nosler +P brass, Fed 210M, 48 grains of H4831SC. Note that one gun shot both very well, the other only shot the ballistic tip load well. In the first gun, 5 shots were going under 0.25 inch C2C at 100 yards.
4) 120 grain partition, WW+P brass, Fed 215 primer, 43.0 grains H414.
One thing I found .. .257s can be twitchy. I've had a couple that would shoot the 75 and the 120 well but wouldn't shoot any of the 85-117 grain bullets I tried with any decent accuracy.
