30-06 vs .300

.300 Win Mag is more powerful than .30-06, so it should be alright. I'd call ahead and confirm that your Garand is okay first, however.

Would there be a reason why it wouldn't be ok?

.300 Win Mag and .30-06. The Magnum is on the left. You'll be fine.

Because a lot of milsurp Garand ammo has steel jackets that spark when hitting the range backstop. If it's rifle velocity, that spark might fly back far enough to ignite unburned powder on the range floor and cause at least some shut-down while they hit spots with a fire extinguisher.

The 30-06 is the most common hunting cartridge on the planet. I wouldn't worry.

Both are 30 caliber....

Not even once

I never understood this. My local indoor range allows anything up to, but not including .50BMG and I was able to shoot surplus steel core 7.62x54r there. It sparked like crazy whenever it hit the end but no one ever cared.

30-06 delivers about 2/3 the energy of 300 winmag

Also, 30-06 and 300wm use the same bullets, OP
