Question about modern ammo

[Patrick Chadwick]

There is a guy on the CMP forum who has done a ton of pressure testing on period and modern ammo in the Garand. Basic conclusion is that any modern 150g ammo puts less force into the op rod and bolt than the original 174g M1 ball. And most current factory 150g is not hotter than some of the snappier HXP M2.

I cannot find a search function on the CMP forum. And there are 650 PAGES of threads on the Garand. Can someone please provide a proper link to the contribution mentioned above? Or tell me where the search function is hidden? Is there one?
