Crimped Bullet Meplat?

[Russell0331]

Hi Everyone,

I was just remembering Ol' Hook and thought about him showing me a bullet that he called "the most efficient killing round".

It was a 168 SMk with a crimped head. I was wondering if anyone had any insight as to how he did this and what the effects of doing so will have on the flight.

I've searched the internet and can't find any information.

Here is what it looked like from the tip looking down.

#1 phillips bit pressed into the tip?

No. It was crimped not expanded. He may have used the negative impression from a Phillips head and inserted it into a die.

Those look just plain nasty. How do they shoot and perform?

The objective is to uniform the meplat to get bullets to perform better at range. You lose a small percentage of BC by doing so.

If uniformity is the objective why not use a meplat trimmer?
