I'm looking at loading some self defense loads in 9mm with Speer's 124 grain Gold Dot bullets.  RCBS makes a custom seating punch for this bullet to go with their Group B pistol dies.  Unfortunately for me, my RCBS Group B 9mm dies are of an earlier generation and do not take RCBS's (now) standard 1/2-20 threaded seating punches.

Is it worth my while to buy a new seating die so I can use the custom seating punch?  I've run into issues where bullets are marked (not necessarily damaged) by seating punches that aren't a perfect match for the bullet I'm using, but I don't know if Gold Dot bullets are fragile enough for a mismatched punch to damage them.

Any assistance on this would be appreciated.

I haven't had any issues with my Hornady dies for my Gold Dots and don't consider them a fragile bullet that marks up easily.

I been loading 147 Gold Dot with small machine screw seat stem with no concerns.. but if case so full of powder that it require some push to seat bullet on top of powder, then you may nose slightly rounded,, but with 3.5gr Titegroup and 147,, no problem

Thanks for the reassurance.  I didn't want to have to spend $20 for a newer seating die just for this particular bullet.

On a related note, has anyone found third party seating punches for RCBS, Hornady, etc. dies?  I can see this being a really interesting specialty market, but maybe only for production-level dies...

I have used a redneck solution when I needed to make a custom seating die.  I have taken aluminum foil and wadded it into a ball. Then stuffed it up into the die and press it into the seating die.  Press a few rounds into the foil to pack it and to make it conform to bullet shape.  Adjust the die to get your desired length.

YMMV

Put a dab of candle wax in the seater.

I had all kinds of trouble with the stem in RCBS dies for .32 ACP with Gold Dots.  I messed with grinding the stem to fit, but it was not perfect.  RCBS sent a correct stem.

Was just going through some boxes of 9mm ammo this last weekend.




There were Gold Dots that I loaded back in 2005. No marks on the bullets, I use Hornady dies.




These were loads from before I discovered True Blue.

Some gold dots (like the 135 grain .357 SB bullet)  can be damaged if you seat and crimp in the same step.

That's really the only issue with Gold Dots.  Never needed a custom seating stem.

Good point, I never seat and crimp in the same die.

That sounds like what Dean Grennell would say.  In fact he did in his editions of ABCs of Reloading,

I also found some stuff suggesting using polymer clay and even JBWeld.  I think poly clay is as permanent as I want to get.

Oh, and I use separate dies for seating and crimping because a lot of bullets don't react well to seat/crimp at the same time.

I had to use wax to shim the seater for my .221 Fireball die, there was no way to seat the bullets I was using deep enough.  I called Redding and the rep knew about the problem and sent the correct stem.

Some Redding stems have a number on the end for identification, maybe all, I never thought to check the others.
