Well, if you want good published data for +P 158 SWC, the best source might be Lyman #46. It has mid-900fps loads (4" universal and he's got a snub) using Bullseye, Unique and 231.

I've not seen data for lead 150 grainers. The only 150s I've seen were jacketed. So if you're molding your own 150s, and want hot loads, data for 158s are your only choice for published loads. I hesitate to post the loads here because the OP was taking the dangerous route of experimenting with really hot loads without a chrono, using only "pressure signs." As someone else noted, by the time you see high pressure signs, you are in dangerous territory. If he is still on this board and still doesn't have a chrono, he can at least get a copy of the Lyman book and start out with starting loads.
