True, but most inexpensive commercial loads for 150 grain bullets
have a tolerable amount of powder for a Garand gas system.
While you could load a 150 grain bullet with a dangerously hot
load for the gun, IME most standard 150 grain loads work well.
Most large reloading manuals also have a separate chapter
or subsection on 30.06 specifically for the Garand.
There is also a "Schuster Plug" or adjustable valved plug available
to replace the standard gas plug, if you want to shoot heavier
loads without damaging the rifle's gas system.
