When I reloaded ammo for my match Garand I stayed around 2650 to 2750 FPS. It always worked and was accurate.

With all due respect to the late General Hatcher, that article was written about 75 years ago. There are powders being used today the the General had never thought of. Absent proper testing, there's no way to know what the port pressure of the modern powders is in an M1. I shot CMP matches with guys with M1s, after hearing all the M&B going on about bent/broken operating rods (unknown powders/load data), I never had any yen for an M1.
However, for those who do reload, the following is the NRA published load data from the last century:
.30-06
150 gr FMJBT/HPBT
IMR 3031-48 gr
IMR 4895-49 gr
IMR 4064-50 gr
168 gr HPBT
IMR 3031-45.5 gr
IMR 4895-47 gr
IMR 4064-48 gr
If your M1 was rebarreled to .308/using an M1A or the like:
150 gr FMJBT/HPBT
WW 748-45.5 gr
IMR 3031-39 gr
IMR 4895-42 gr
IMR 4064-44 gr
168 gr HPBT
WW 748- 43 gr
IMR 3031-39 gr
IMR 4895-40.5 gr
IMR 4064-41.5 gr
Note: loads for the obsolete 173 gr flat meplat "match" bullet are given, but this IS NOT THE 175 Gr Sierra Match King, so it's not included.
Hornady has a section in it's load data for service rifles that shows a wider range of powder selection that apparently still stay within the acceptable port pressure range. The powders listed seem to be in the same burn rate area.
General Hatcher would disagree...
In days of yore, surplus M2 ball ammo was nearly as cheap as dirt and probably spurred a lot of interest in the M1. Not sure when that evaporated.
It's not the velocity you should worry about. It's the pressure curve of the powder used to load the ammo.

Have used this data for many years with great success, especially the 150 FMJ and IMR-4895 at 49 grains.
Point of aim and impact is the same as M2 Ball, ejection is the same pattern....must be a near perfect replicant of M2 Ball.
