FA,
I'm scratching my head on your load and spring choice.
MAX LOAD FOR RAMSHOT COMPETITION POWDER is a 230 grain bullet over 4.0 grains of powder. This will give you a power factor of 185 (20 above need for major). You are adding another grain of powder to that.
You have picked the fastest burning of the Ramshot powders.

If you are going to stay with this load make sure you are running a buffer! You are going to beat your gun to pieces, and a light recoil spring will just make it worse.
My recommendation,
and this is just my opinion based off my experience, Stay with Ramshot, drop down to a 155 grain semi wadcutter moly or jacketed hollow point if you can find them, and dial in your powder for a 1,095 fps average. This will give you a 169 power factor.
From my research the above load is within SAMI and Ramshot specs for reloading, but I will leave it up to you to decide if it is right for you.Fast burning powder pushing a light bullet fast will give you less felt recoil. You will need to play with the springs to see what is 100% reliable, but I would add the buffer if you go to the lighter spring.
In my open gun I am throwing 155 grain at a power factor of nearly 200, and I use a light spring and a buffer. However, with the compensator I need that power to operate. Even with that power it is smooth and low felt recoil. With your stock (basically) 1911 you don't need racing fuel. Pump gas will run you just fine even with these minimal modifications.
Last thought - Experimenting with springs is like finding a holster you like: You can end up with a box full of "experience" before you know it

Enjoy the experiment, keep lots of notes in a permanent notebook for the gun, and don't be afraid to back up and start over.
