220-240gr bullet, exposed lead tip is ok by me, it has to be easier to mfg than a super small hollow point and keep the BC up there, a VLD boattail more than likely, copper plating would probably be less than .006 at the most, perforate the plating at the tip and pure lead core could expand like a round ball from a MZ loader.
Most of all, we are all excited that someone wants to make a bullet specifically for us. Cool!
FYI: Diamondback Bullets has sent me 6 prototype 220 gr bonded core bullets to try at subsonic. Will post results. Also contacted Hornady about making a 220 gr or better with their flex tip technology for sub use. They said the info would be passed on to their engineers.
Tried to find out what happened---Sent e-mail to Berry------------------------------------------------------------------------------------
Robert,
Sorry for the delay, we have been very busy moving into a new building and trying to stay ahead of orders. The research I did into making a heavier bullet ran me into a length limitation of what can be made using our current presses. Current tooling limits us to the 150gr bullet, I did find a die profile we had that is a pointed nose. I am not sure if this is much help other than being able to be shot in the AR platform since the FP cannot.
Why do expansion when fragmentation at subsonic velocities has already been proven? Make a .30 cal version of the bullets in the CCI .22LR segmented HP subsonics. I have dissected these and they are segmented with 0.080" depth (1/3 of .224) cuts on the outside of the bullets. I suspect that the cuts are on the outside because the segmenting is done to the lead wire while it is still in the spool. That would make sense for mass production. Then bullets can be made from those spools on existing equipment.
RCECO also has a nice note on swaging pre-fragmented lead bullets the manual way in chapter 3 of their online manual.
150gr. would also work in subsonic loadings for conventional 308 barrels...

I wouldn't mind a 150gr pointed bullet for subsonic plinking. I currently use Hornady 150gr FMJs for an inexpensive plinking load. The Berry's would probably be even cheaper.
