Shock is different. I myself don't find 150gr of powder to be harsh like most claim. Maybe cause I use a good recoil pad.

I will be the first to admit, that I probably haven't heard or know everything. But with all the people I now conquests, I figure I would hear something or another about recoil affecting them. I do know alot of people that has sent back thier leupolds at least once for fogging or suspected recoil issues.
