Best Bullet Weight

[strycnine]

I'm in for some 220's. How thick is the copper plate?

[MIKEONE]

How bout something like this in the 220-250gr range. Flat base, truncated ogive, wide meplat, HP .308-.309

Your .429 240

Looking forward to your comments on what is practical from a manufacturing point of view. I think, to summarize comments so far, we want everything:

a. a very heavy bullet (220 to 250 grains)

b. with a hollow point that expands at low velocity

c. that feeds in a semi auto

For me, the reason I like the Whisper concept, is that tumbling factor. Noting that a 1/8 twist barrel in theory causes the 240 grain Sierra MKs to tumble after hitting something, would a rear heavy subsonic bullet at 250 grains do the same thing? And would a long, small diameter hollow point assist in making that projectile unstable at subsonic velocities?

[HUNTER2]

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.

Well Put. +1

Ooh, very interesting...
I occasionally shoot 200gr cast gas check (Lee mold) from my whisper but never with the can attached. I believe a plated bullet would take away my worries.
A 220-250 (maybe even heavier? I can dream can't I?) with whatever point it would take to keep from deforming in an autoloader (AR15 based) Just make sure it can be used in a standard AR16 magazine when loaded with a subsonic charge. I don't think a boat tail would be needed since at subsonic velocity the difference in drag/ballistic coeffecient would be insignificant.
Maybe a truncated cone? it would give a strong tip and acceptable ballistics. A pointed tip would be great for targets but not as good for hunting. Hollowpoint would be awesome but how would it affect the price and accuracy? Roundnose, well, they are out there and they are used but are only popular because there ain't much to choose from on the cheap end of the bullet scale.

Jay,

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!

Thanks.

I need a bullet to expand. Unless you do head shots on animals, the animals tend to run, and the blood trail is sometimes difficult to find.
