Due to the drag being on the rear of subsonic projectiles - BT or RBT would be far supperior to flat base ( long distance ). 220, 240 BT with HP that will expand - mark me down for 2,000.....200 gr .357 if you are looking for some more to make. We do appreciate you looking into this.....

This is the reason I contacted Berry's to start with. I just killed a doe last Friday with a 240 SMK. Slight quartering-to shot. 30 cal entrance hole and 30 cal exit hole. No tumbling at all even after hitting the spine and deflecting down and out through the ribs on the other side. IMHO, an expanding bullet would be much more of a game stopper than continuing to HOPE for the bullet to tumble.

Thanks for the Input
 

Thanks for all the input, I have been talking to our engineers about what we can make with exsisting tooling. We will have to make some of the tooling so I am going to have to post a thread when I have a better answer. We will be limited to between 200-220gr due to the OAL of our current dies and setup for the presses. I am convinced the expansion on our bullets will be perfect for the Whisper. Once again thanks for the response.

Jay - good news.

Scoop - how long did it take to find the doe after you shot it?

Gelatin Test
 

Since I don't have access to a 300 Whisper, how about if I supply 100 of our 150gr bullets and a tube of ballistic gelatin to one of your members who would be willing to load and test for all of us to see. I will leave it up to this forum to pick a member to run the test and provide us with loading data and images of the gelatin results. I have a Bullet Test Tube sitting behind my desk and I would like to see what our 150gr FP does pushed through a Whisper.

I would like to see something in the 240-250 grain range with a decent BC and an expanding hollow point design. Ability to feed in an AR weapons system would be nice as well.

I can help
 

I would also be interested in a lot of these bullets. We are tooling and developing loads at Center Street Brass/Crossfire Ammuntion in Provo UT to load subsonics commercially for the 300 Whisper. We already do a lot of business through Berry and are down there weekly to pick up bullets. I would be willing to help with anything that is needed and we are VERY excited about the possiblity of 220 grainers that expand at sub-sonic levels. We would be in for at least 3000 to start and untold many more.

Fortunately the shot was high and hit the spine. She dropped where I shot her. Good thing too, as there was very minimal bleeding through the exit hole and none at all from the entrance (I had to probe around with my fingers and pull hair back just to find the hole). Following that blood trail would have been a real "on-hands-and-knees" experience. No doubt a hole through the heart or lung will kill a deer, but finding enough blood to follow will require a larger exit hole IMHO. YMMV.

I'm willing to do the testing. I aready have plenty of your 150 gr Flat point bullets (I load them in .308 Subsonic for use in 12-twist barrels). I'll just need a general protocol and the gelatin. What say the group?

I would also be interested in something between 240-250 gr. 220 would be nice but I'd really like something at 250 with some degree of expansion.
