change recoil spring when going hotter?

[Mark]

I have read about race guns in .45 and Supers and I am not into that. It is the thought of understanding motion in relation to power. There were articles about changing the recoil spring to 10 pound spring, etc when performing this type of load. Blah, Blah. Does that mean if using a pet load, spring could be lighter for better recyclibilty and smoothness and for hotter loads to change spring to heavy in order to protect the frame,,,, Please fill me in.
I was wondering if I was to use a real hot load in the Kimber Team Match II would the spring need to be changed? Or will the spring handle all types of light and heavy full power loads without changing it?

What is the case on unsupported or supported barrels? What are they?
Kimber is unsupported???
Thanks

Depends upon:
1) How "hot" is hot?
2) number of "hot" rounds you intend to fire.
I would say to be on the safe side, if firing more than several hundred of your hotter loads, change to a heavier spring.
I notice that Kimber recommends changing recoil springs every 1000 rds (at least on my Kimber 4 inch bbl 1911. ) So changing to a heavier spring might not be a bad idea if you intend to fire alot of hot loads.
