I have a 1K box of Rainier Ballistics 130gr plated bullets in 38 super that I happened to get on clearance a couple of years back. I measured a handful of them and they happen to be roughly .3565 to .357 in diameter. I was wondering if it's a smart idea to try to load them in 9mm brass? Is the combination of plated bullet and the diameter just too much for 9mm? :scratch:

I don't think you'll have any problem at all. But, as Blacktail said, make a dummy round or two and give 'em the plunk test.

They can be resized to .355-356 with a push-through resizing die.
That's not a problem.

But the shape of the bullet will be.
I ran into this a while back.


The 9 Luger is a very sleek shape.
Rounder bullets will have to be a lot shorter to chamber.

And what that does to the pressure profile is anyone's guess.

This was a 125 grain powder coated case lead bullet fir 38/357 resized to .355.
OAL 1.150
They ran fine in the Range Officer.
But in the little Sig p938 the bullet would not chamber.

The bullet stuck (hard) in the chamber and had to be driven out.
Not a squib, since the primer was never touched, but it sure felt like one.

Do a plunk test on your barrel to find out what will or won't fit.
And make very sure you have some room left to allow the bullet to get moving
before hitting the rifling.


For what it's worth...

I believe 38S and 9mm are the same bullet, .355 in a jacketed. For that matter so is a 380. Lead will be sized a bit larger of course. At least that is what I thought.

I routinely shoot .357 plated in 9mm, 38S and 38 Spl.

I also cast and reload NOE, .358 sized .357, 135 grain, LRNFP, soft lube. I clean my barrels with a rolled up paper towel, absolutely no leading! (USPSA Minor loads)

No issues, if you like stellar accuracy!

Smiles,

Actually, except for the sizing die you could probably reload 38s and 9mm with the same dies, you'd need to adjust them a little.

I routinely load and shoot .358 Blue Bullets in all of my 9mm guns.

Not realized by many that 9mm (9x19), 9x23, 357Mag, 357Max, 357Sig, 38Spec, 38Super, and 380Auto all share the same 0.346" bore and 0.355" groove, that is if you believe ANSI SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) Z299.3 – 2015.
Now the bullet dia vary from 0.3555/-0.003" to 0.358/-0.003" for jacketed and on up to 0.359/-0.003' for lead. Know that all machining has small discrepancies allowed in the tolerances shown.

Its not the "38Super" that matters it's the diameter and then the weight. "38 Super" is the same diameter as 9x19 and 380 (at least), it's the same bullet to an extent. Those are right sized for a plated bullet, will work just fine in 9x19 but you won't find any load data for 130gr and you'll just have to use 124gr data or as close as you can get in weight.

I have a 9 at bar-sto getting a 38 super barrel fit right now. I'm going to order a 357 sig barrel for a 40 sig 229 also. Could get a 22 conversion for either one and shoot 3 calibers with one gun.

Hodgdon's website has load data for 130gr

Luckily Hodgdon Reloading has 9mm 130gr loading data. I'm going to use 3.7gr of Titegroup. I created a round and it plunked in the barrel of my Sig P320 and the 9mm case gauge just fine. :rock:

If I may ask, what are you pushing the lead with? (Not the newspaper):biglaugh:

Sorry don't understand your question, there is no lead in the barrel!

Or are you asking about propellant?

Tightgroup for 38 spl., Win. Autocomp for 9mm and 38 Sup!

Sorry, the LRNFP as you mentioned.
Years ago, I used to load some of those in a 148, super soft with 231 in a 357 case. Ridiculously accurate.

Technically, the 38 Super is .356 and the 9x19 is .355. There has been a tendency to make 38 Super guns at .355 for obvious reasons. But if you shop for bullets designated for the 38 Super, they will usually be .356.
