9mm Blackhawk mold
« on: August 04, 2008, 01:14:47 PM »
Anybody have any suggestions for a mold for a 9mm Blackhawk?
I thought of using  a Lee tumble lube unsized, so it will cast a little bigger to make up for the difference between .357 and 9mm.
Anyone used a different mold that worked for them?
Thanks
Alan

 Alan, I am a  bit confused here. Isn't the 9mm a .356" diameter bullet ? That would make the 357 about perfect for the 9mm cast bullet.

Most 357 molds are going to be a little long to seat and I am trying to get a larger diameter bullets to fit.
I thought a Lee tumble lube mold "as cast"  without sizing would fit the bill. 
I just hoped someone had used this and it worked for them. I am aware of the slight size difference in the two.
BTW This is a Blackhawk 357/9mm convertable so the barrel is for the larger bullet.

Years ago I had a BH .357/9mm convertable. I shot lots of 358477s sized .358 in 9mms. I backed the size die out a tudge to just partial size the cases where the .356 diameter plug of the .38/.357 expander woud be a slip fit in the case mouth. It belled the cases ok.  I seated the bullets so the case just covered the lube groove. This let the bullet enter the cylinder throat aand probably helped with accuracy.  The taper crimp die removed the case mouth bell.  I used Unique (sorry forgot the load) and was getting right at 1,000 fps with them out of the 4 5/8ths barrel.  That load shot as well as my best cast .357 load (both would do 1 1/2" or less at 25 yards going twice around the cylinder) Never should have traded that revolver off........
