In my youth - when the DCM would sell you one M1 in a lifetime, with an oath to not resell it - we were warned by NRA not to reload for the Garand with 4350 or 4350 Data (surplus 4831) powder because high port pressure from slower burning powder could bend the operating rod.
When Light Magnum ammunition came out, we were warned by Hornady not to shoot it in the Garand (or any autoloader) because its highly progressive powder would generate excess port pressure, etc.
Now we are warned by Internet Experts not to shoot ANY commercial ammunition in the Garand because "you don't know what powder they use."
While I have trouble imagining an ammo company using 10% more of a slow powder to generate the same standard velocity as they could get with 10% less of a medium powder, I guess there is the risk of them getting a deal on such slow powder.
So I am asking, has anyone actually seen a Garand operating rod bent by use of name brand standard load commercial .30-06 ammunition with 150 - 180 grain bullets?
