I used the Berry's hybrid hp 180s in light 10mm and had key-holing every 6 or 8 rounds even within the published velocity envelope which is down to 40s&w velocities. Crimp so light to just remove belling too.
NO- GO
In 9mm I had the 147s not expand whatsoever, even when pushed to published maximum and averaging over 1,000fps.
I would recommend these Berry's bullets as a last resort when there is no other hollow point design on the planet available. I'd trust any LSWC over these Berrys bullets. I also LOVE the X-def available from Xtreme bullets. Much better success with this, reminds me a lot of a Gold Dot.(Xtreme X-Def)
Sorry, Berrys!!
