Can you buy 30-06 ammo loaded to the old specs?
Consider a Schuster plug that you can tune for any ammo you want:I always heard that WW II 30-06 ammo was loaded to lower pressures than todays ammo and you could not shoot modern ammo.
But the CMP web page basically says not to shoot heavy bullets greater than 150 gr.

The ammo thing has been debunked over and over. Bent op rods are the result of people that don't know how to properly lube a garand.
Buy from the CMP, I would get a service grade but they are out of them currently. The grade descriptions are accurate, if you don't want to wait for service grade rifles to come back in stock then read the descriptions and get what makes most sense for you.
FFS, no, it hasn't been "debunked over and over". Yes, there's nuance to the issue, but it's a real thing - there's "Garand Safe" ammo, and everything else. Some types of ammo are fine, some types are very much not fine. Add in binding or poor lubrication and the situation gets worse. One clip of ammo may or may not be a problem, but a case of heavy bullet stuff with a slower burn peaking at the gas port is probably going to cause increasing amounts of damage.
It's like saying "Driving twice the speed limit is fine, it's been debunked over and over again that you can't do it".
OP, if you want to read a good article on the issue, this will help. The plug they sell is a good option.

20 yrs ago, my son was spitting 150 gr Core-lokts through a 1942 Springfield like sunflower husks. I didn't really care because I paid $100 for the Garand. 100 rounds through it without damage (cause I only had 5 boxes of the Core-lokts). He killed 5 or 6 deer with it, then it went back into hiding.Don’t shoot standard -06 in them.

WARNING!
Dear CMP Family,
The CMP advises to not use .30/06 ammunition in M1 Garands, 1903s, and 1903A3s that is loaded beyond 50,000 CUP and has a bullet weight more than 172-174gr. These rifles are at least 70 years old and were not designed for max loads and super heavy bullets. Always wear hearing and eye protection when firing an M1 Garand, 1903 and/or 1903A3 rifle.
This warning is an update/addition to the Ammunition section in the Read This First manual enclosed with each rifle shipment (M1 Garand manual-page 6 and M1903 manual-page 10).
