So my 357-180-sil bullet requires maximum oal of 1.590 when loaded. Where would you seat the bullet? Currently I'm using 1.580 but may up it to 1.585 when I get crimp growth figured out.
 
I would seat them as far out as possible where I could get a good crimp.
But not too far out to where the bullets will jump out from recoil and jam the cylinder.
Assuming they're for a revolver?
 
What's the problem with using the crimp groove (assuming it has one...)?

Looking at generic pictures of that bullet online and it seems like using the crimp groove should work for most applications.

What you think is a crimp grove would exceed sammi spec by a lot. My next batch I'll measure
 
What gun are you shooting them in? Not all .357’s have the same cylinder length. 1.59 is listed as .357 Mag max OAL for the ammo and that should work for any gun however most newer guns (GP100 & 686 for example) will have longer cylinders.
 
You will likely need loads specific to each gun if you want to get all you can from your handloads.
If your wanting something to work in everything I would think you would have some better luck with a more common weight bullet like a 158.
Good luck

When moulds become reasonable again I'll be hunting down a 158 round nose flat point. This situation is just a short term solution.
