The ad is a bit misleading. I do not think the writer has ever shot a gun. The Hyrda-Shok is a fairly traditional jacked hollow point bullet (a center post added). The "EFMJ" is a different bullet entirely.
The 165 gr in a .45 is a light weight bullet. Recoil is more dependent on bullet weight than velocity. The 165 will recoil less than a 230, but will have significantly less sectional density and less penetration.
