Load for a 357 - 150 Grn SJHP with Uniqude

[KnotRight]

I am having a hard time finding a mid of the road load for a 150 grn SJHP for a 357. I am using Unique powder.

Any suggestions?

If it were me, I would use data for a 158 grain JHP.
I like 6.0 grains Unique with 158 jacketed or plated in .357 brass for a 'mid range' load. I would not count on proper expansion of the hollow point at those speeds, but it's a pleasant load to shoot.

Well I would check with the manufacturer and see what they reccomend first, and if that isn't an option,

As mentioned there above, using the closest, next heavier weight up bullet will work just fine in most cases accounting for any major differences in design. Usually the bearing surfaces, or how deeply they might be seated, are what you would pay close attention to. If your seating to the cannalure then they should load and shoot just fine with no pressure issues, especially if your working up slow. Just stop when you reach a load your happy with. Remember though, the heavier weight bullet loads will probably stop just shy of where yours would be on the top end, so you should have that medium range loads your asking about.

I usually load for accuracy first anyway, so if it happens to be on the upper end I'll take that as well.
