I just finished loading 400 rounds of 50AE... half were factory Speer Brass, and the other half were factory Starline Brass.
-Speer/Starline Brass
-Winchester Large (magnum) primers
-Lee Steel Loading Dies
1) Deprimer/resizer
2) Expander to "bell" the mouth to accept the bullet
3) Bullet seating die
----------So, I'm watching a couple youtube videos on a guy loading some 50AE and he's got a 4th "Crimping" dye to roll the mouth that was belled slightly into the bullet.
His explanation was that usually crimping is not required for self loading pistols... but on revolvers, the recoil can make uncrimped bullets move forward or back (usually forward, then the cylinder wont turn if the bullets start coming out slightly).
So, he was loading 50AE and he did have a 50AE 4th crimping die... I checked Lee's page and they say they don't make a 50AE crimping dye because :
Custom Carbide Factory Crimp Dies for handgun cartridges can be made for most handgun cartridges that are not in regular stock. Sizes available run from 25 ACP sized cases up to the 480 Ruger. The 50 AE cannot be made because the carbide ring necessary for this cartridge is too large for our manufacturing process.
I couldn't find a 50E crimp dye on RCBS either... so I guess it must not be "that" important?
I've only shot a few dozen rounds thus far and they shoot well... so I must be doing something right?
