Swagging slugs

[waffenspectr]

How exactly you made that ogive shape using lathe machine?

 

[warchlaq]

Enough for today. This is what it will look like. Tomorrow, or rather today, I have to hardening it.

I haven't worked on the exterior so far. First, I will check the dimensions after hardening. This steel is not very susceptible to deformation during hardening, but it's better to find out for yourself

Heating, my gas burner sickened something, so I have to heat up with a small cartridge burner.

The end

 

[warchlaq]

Two piece die, the ability to change the shape of the head of the slugs. Not processed from the outside.

 

[warchlaq]

Slug 2,195 grams, only 37m, but I think it's a good start. 20.5mm coin size

 

[warchlaq]

Interestingly, with that longer cylinder part they are pretty cool. 37m, 5x 2,195 grams, .22 Alfaprecision polygonal barrel not choked. Shooting position ... leaning against a rabbit cage.
That single hole, the aiming point.

nice group at what speed you shoot them from your new barrel

Very nice! Thanks for sharing! I'd be interested in trying something like this if I understood how the swaging dies were constructed.
