We all been there, I learned about the Lee Factory Crimp Dies and I have one for every caliber I load for now. 357 is a easy caliber to cast and load for. Not much more than shooting a 22 LR.

I’ve used those same dies for my 45 Colt. I didn’t like the crimp/seat in one process either so I just use my lee seating die from my 45 acp set. That crimp die is designed to give a very heavy crimp. I’ve noticed that the crimp appears more like what you’re going for when using cast boolits than with jacketed. For me though, the heavy crimp is quite necessary when I’m shooting +p loads out of my ruger blackhawk. 360 grain hard cast produce quite a bit of recoil…

Just get a lee factory crimp die-this I use on pretty much everything I load and never have problems. Been reloading off and on for over 50 years and this makes your loads chamber no problem !

If you have a combo crimp/seater die… Back the die off so you do not crimp at all then seat the bullet. Then without the seater plug or way backed off crimp the bullet. 2 steps, 2 die settings or you can cause those problems.

Hey Chico
You are on the right trail…….Just keep working on the seating depth. I have used a set of RCBS dies for about 40 years and it take time to get it right but they are great to shoot. Keep it up brother.

Nice video. It is always and adventure when starting a new cartridge or new bullets. You have some great comments with good info below. I have to experiment with seating stems a lot get the right fit for the bullet. Just make sure you put a good solid crimp on those 357. Take care and happy reloading.

There are a couple of things you need to look at. First, there are different seating plugs avai li able. They are designed for different bullet s h.g apes. Using the wrong plug causes the bullet to deform. As an example, a JHP bullet would use a different plug than a RN bullet or a wad cutter bullet. There are two adjustments on a typical seating die. The first seating adjustment is how far down you screw down the am seating die into the press. On a 38 Spl/357 mag. seating die, you h.g ave the roll crimp built into… Read more »

Hello Harold these are some awesome pointer’s I would like to humbly state that the crimp is adjusted on the die *After* the bullet seating. COAL is achieve. You can verify this with RCBS. See my post below for there recommend way

Chico – Nothing wrong with being a rookie reloader…we all have been there. Bullet deformation on seating is caused by 1) improper seating plug fit to the particular bullet being seated 2) inadequate case expansion causing excessive bullet seating pressure 3) seating bullets that are the wrong diameter – for example – seating 38 Special bullets in a 9mm case. Bullet deformation can be severe like the cast bullets that developed the wadcutter look, or even the slight ring in the jacket of the Hornady XTP bullet on the far left. Good reloadin’ to ya, Steve

Chico, my RCBS .38/.357 die set came with 2 seating stems. One for round nosed bullets, and one for semi wadcutter bullets. I think that the ‘Giorgiaboy’ bullet may be too wide at the tip to even use a wadcutter stem, so you may have to check and see if RCBS has another stem available for possibly a full wadcutter?
I use my RCBS die to provide the roll crimp, and it’s worked okay for the past 30 years. What Kenny said would be a good way to set up your dies.

Hey Chico! I use to like having the Lee roll crimp die untill I figured out how to setup the bullet seating die with crimp correctly. I prefer the RCBS bullet crimp die. How to setup it up correctly is 1.)insert a empty case then screw down the die untill it just touches the case mouth 2.)turn the seating stem and seat a bullet untill you get your COAL 3.) BACK off the Seating stem on that cartridge you just seated the bullet. The screw in the die until you get the crimp you want. 4.)Using the same cartridge now… Read more »

Chico I am in the same boat I got some 38 brass cleaned and ready so I am new to reloading 38 myself. You have to stumble at first before you run with it.
