The Berger is allready an extremely faster expander with its thin J-4 jacket... Why would you possably want it to open faster?

On the AR forums someone said they had some penciling problems. With a tip wouldn't that be nearly impossible?

There is little question that polymer ballistic tips do not deform in the box, the magazine, etc. like lead tips do on bullets.

I am not saying that a polymer tip is not of value in this new concept, but that it is not a focus for the development because we are focusing on the core of the bullet and not the exterior. That is where I feel we can make the biggest contribution.

jwp: That was exactly what I was thinking. I've hunted with Bergers for 2 years now and there is no need for more expansion. I have shot animal up to 700 yards and shot a deer at 15 yards and at both ranges expansion was perfect. If I wanted any improvement on the berger it would be a higher b.c. which would be hard to accomplish. Retaining there accuracy and staying at berger's price would also be tough also imo.

IMO, you have a lot of different issues here.

BC, in short is based on the shape and the SD of the bullet. Make a normal bullet out of aluminum and the BC goes down, make it out of tungsten and it goes up.

Most rifles have a twist for normal bullets. If you plan on making an extra long bullet then the rifle maker would need to make it with a tighter twist.

The Drag is not just one item, it is Nose drag ( which is the largest drag ), then there is Base drag and Skin drag.

I think that most target bullets are hollow points because it is the easiest shape to make consistently accurate.

edge.

With the accuracy people are getting with several bullet brands, it is obvious that we are not going to develop a more accurate bullet in the sense that it will arrive at the target 1000 yards downrange consistently in a smaller group, only one that perhaps shoots flatter with less wind deflection. While that in itself may contribute to accuracy, bullets made today from most manufacturers are amazing achievers. I can only guess that pricing will not be affected to a great degree.

We are receiving a lot of good input from this forum and our technical research. The secret to making this bullet will be to make it so that it performs like a bullet with proper expansion and weight retention while achieving the ballistic expectations of shooters. I realize this is a tall order. We may fail, but it is an effort worth expending. By the way-- I fully expect to succeed.
