I just got a M30 and plan to work up a load for the 100 gr XTPs I have.

My Lyman 45th (which is older so tends toward hotter loads) lists:

93 gr cast SWC bullet
Bullseye 1.4-2.7
Red Dot 1.7-3.0
Unique 2.5-4.3

That last load seems very hot - 4.3gr is a a lot in that cartridge. I'd start around 3gr and work up with a 100gr bullet.

My Speer #8, known for very hot loads, has:

95gr cast SWC bullet
Herco 3.2-3.7
Unique 3.0-3.5
SR7625 2.8-3.1
Red Dot 2.5-2.8
Bullseye 2.2-2.4

The Herco load is something I'll be playing with, as I have a pound I'd like to use. With these Speer loads, I'd start with the lowest loads and work up, as even some of the starting loads are very hot.
