Putting 357 158 gr lead in 358 Win Case

I tried up to 15grs. of Unique in my .356 Win., which is similar to the .358, accuracy with hardcast gascheck bullets was not up to par, even hard ones. Accuracy improved as I went to heavier and longer bullets, cast rifle bullets that is, the 250 gr. flat pt. was deadly accurate at 1200fps or 2100fps.
 
6.5 grains of Green Dot under a 158 grain jacketed .358 dia HP bullet
"My" velocities are around 800fps

For reference only! This works in my gun.
Test thoroughly to be sure they exit the barrel every time!
