Deforming against a solid concrete wall isn't expanding through a tissue analog either ;p

I'll do some testing JSR with ratios like your 2/3 hollow tail etc and see which gives good results,but are also reasonable.


The ratio will depend on how thin the walls of your hollow section are, but generally aim for a centre gravity around 25-35% of the total length from the nose.

It might well be easier to make a lighter tail of solid plastic or wood than try to make a hollow lead section.


Sound advice, it's the principle behind the Brenneke type slug:

Not casting eh?

Pounding lead sheet into a bullet shape sounds improbable...

Fishing sinkers? :wink:

I was thinking along the lines of a lighter tail,something like thick felt or dense foam.

I also had the idea of adding something of a "tail" to the design,I could drill/bore a small hole in the back of my round and add a small length of copper wire soldered in.Although I'm not sure how well it would work.

@Hotwired - My dad has a background in Glass working and Lead lighting,so I have copious amounts of lead lying around and I've made my own little way of producing these and it works pretty damn well.

You will see soon.
