Subsonic expanding bullet

[Expatriot]

how much difference wouls a cast boolit make on expansion versus a jacketed one?

Depends on what it is cast out of. Some alloys can be very hard and won't expand at all.

I've had some correspondence with Hawk Bullets and they told me they don't stock bullets made for the Whisper but they do periodically make runs of them. The bullets are 220gr or 250gr round nose bullets with very thin jackets (less than their .025" jacket). They also said that the 220gr will feed in an AR but the 250gr requires single loading.

They have put my name on the list for when they make their bullet run. They didn't provide a timeline but if you are interested contact them at info@hawkbullets.com
