looking at 250gn lead boolit loads for 45c,Richard Lee's modern reloading says ,starting load 8.4 of unique max 9.5 Laser-cast(the boolit I'am using) manual says starting load of 6.7 max 8.1 What gives?
For .45 Colt, you have data for the original SAA and you have other data for Ruger and T/C Contenders. Best to start with the data for the SAA.
Then again, do you have the same powder lot number? Do you have the same bullet? Are the bearing lengths of your bullet and their bullets the same? Is the COL the same?
Next, Lee took the loading data from many sources and did some sort of "normalization" to reach the data printed and, in most cases, is tilted to the "better safe" region.
Do what folks have been recommending for about 80 years--check multiple sources and start at the lowest start load you find and work up.
There are simply too many variables to believe that any data is "better" than any other and you should always go for safety.
If you want, start low and only load 1 or 2 rounds just to see how they do and work up from there, but any of the loads will get the bullet out the barrel and onto a target at 50 yards, so enjoy shooting them and see what works best in your gun.
Lee's data was not shot by Lee. It was copied from other sources. I don't think Lee even has a ballistics lab.
Even if you use all the other printed manuals you will find differences due to different test guns, testing facilities, powder lots, bullets and primers.
The best that I can recommend is to buy 5 to 7 totally different manuals. Take the high data and toss it. Toss the low data too. Take the data from the 3 sources in the middle and average it. Be sure and work up your loads for safety.
the Lee manuals always seem to be on the hotter side. I don't use it much. Look over as many sources as you can, you may find a common ground, within say a few 10ths as a start. i.e. Sierra starts at 6.5 to 8.2...Hornady lists 6.1-8.5, Hodgdon 7.0-9...try a start around 6.3 and you should be safe. **I made these numbers up for an example** Like PM said you will get feel for it. You could even start at the lowest listing you find.

Additionally the Lee manual has not been updated in many years!
