Introduced last year, the new Winchester USA Ready Defense Hex-Vent seems to be the newest of the pre-filled hollow point bullets designed to help ensure expansion when fired through barriers. According to Winchester the Hex-Vent rigid insert “Shields hollow point from obstruction while channeling material flow for positive bullet expansion”. There is a web lint on the box that will give you the velocity and pressure info on the lot of you have. However it didn’t appear to be working when I tried.
