The 308 corresponded to a major advance in smokeless powder which came in 44; it didn’t need as much powder to get the same ballistics as the 06. What I was saying was that if you load that 30-06 case up full with modern propellants, it’s likely to generate more pressure than a Garand rifle was designed for.

It really depends which powder you use. I can fill a 30=06 case full and packed down with 870 and it will fire normally. I can take a m1 carbine and fill it full of a fast powder and blow it up. Powders come in very slow to very fast burning.
