I finished up some more customer dies and had some fun making some .375 bullets. Had great results making jackets from 9mm, 38spc, 357mag and 223rem brass. I know severial others here are shooting the same 375 bullets made from either of these cases, maybe they will chime in.
Each case has unique requirements to use for .375 jackets. The 357 mag is a bit spendy, you could sell those for nearly the price of new comercial jackets but the rest of the choices are a lot cheaper.
All require to be resized slightly and more so in the case of the 9mm. This is easliy acomplished pushing the cases completly threw a 9mm taper crimp die.
The 38 and 357 need the rim removed. This can be done on a lathe (slow) or with a shear die (extra cost). Both works fine. I turned the rims off in the lathe because I misplaced or more likly remachined my shear die for some other task.
The 223rem is a good choice for heavier bullets (200 grains on up since the 9mm works so well for 240 and less) but needs to be trimed. Very easy and quick if you can master a simple jig with a mini chop saw and altered case trimer (I have posted lots on this technique.
I used various pieces of lead for cores but the .312 95ish grain cast boolits 2 per case work good. Males the 240 grain bullets pictured.
So how about some pics! Just one for now.
What we have here is bullets made from two different point form dies. One flat nose for the 375win lever action shooters with a .220 metplat and the other a standard point or spitzer with a .130 metplat.
From left to right,
200 grain FN from 9mm, 240 grain FN from 9mm, 240 grain 9mm SP, 240 grain 38spc, 300 grain 38spc, 300 grain 357mag and 340 grain .357 mag.
Good shooting and Swage On,
