357 magnum

[Jurist]

I have 200 RUAG 158grn 357 magnum FMJFN bullets.These bullets do not have a crimping groove,can I still roll crimp these bullets?,and will the crimp have any adverse affect on pressures?.

For my wheel guns I roll crimp them to around .376.

I usually back off the crimp die a bit so it gives more of a good solid taper crimp,thus not biting into the bullet.Never had one shift in medium power loads.

I would taper crimp them.
With the continued success of the D.E. and Coonan, taper crimp dies are more prevalent than ever.

Say Jurist, are those RUAG bullets an exposed lead base or are they an encapsulated solid?
Thanks , JT

If you keep the loads fairly light, you shouldn't have a problem with them jumping the case mouth. But I wouldn't recommend loading anything to robust though.

Your good with a very slight roll crimp but much more & it`ll cut the platingwhich is thin compared to a real jacketed bullet . Also if pushedmuch over 1k the plating will give up completely !The brand I had the plating was running around .003-.007"

When I tried plated bullets I pushed em too hard & had shreds of plating in the bore , but I was lookin after every shot !
