Double End and Button Nose Wadcutters at 357 Magnum Velocities

[refuse2bafool]

I use the x-treme plated DEWCs like "refuse2beafool" has in his picture. I don't crimp in the fake crimp groove. I let them stick out like Tilos is showing in post 20 and use a taper crimp on them.
That cannulure isn't deep enough for a good roll crimp.

I am just finishing up my Extreme lead DEWC and have not used the plated ones yet. At 38 special target velocities in a GP100 357 I would not expect any creep on the bullet, but I will keep an eye out for it.

I load WC in 38sp cases (or 357 cases), seated/crimped in the lube grooves.
This approximates the case capacity of a 357 and the OAL cannot be mistakenly chambered in a 38sp cylinder because it is longer than the cylinder.
So, yeh, can be loaded hotter than 38sp but not 357 top loads.
A pic (not mine):

When chambered, the bullet is actually in the throat...
Using coated bullets makes the bullet hardness irrelevant.

edit: I have posted this many times, sorry for the echo.

If you cast ... you would like the Lyman #358432 / NOE # 360-160-WC PB (360432) design ...
Look at the design on the NOE website ... I don't know how to post photos / drawings or I would have .
What echo ... a good post bears repeating...

[.38 Special]

Compressed loads in pistol rounds wasn’t a road I was prepared to take.

So not a fan of H110?

Hodgdons online tool has a bunch of data for .357 Mag loads with LHBWCs in the 20,000 to 24,000 PSI range pushing above 1,000 FPS. Vihtavuori’s app has 3 loads over 1,000 FPS with copper plated WC’s. If you want something faster than that personally I’d just use a different bullet.
