357mag reloading question

[kenworth1114]

tried to load the Nosler 180 grain partition handgun bullet in new Remington brass and it bulges the brass ,anyone have that problem?, I have loaded these bullets before but in brass that had been fired with no problems, can't chamber it,you can see the outline of the heel of the bullet. I didn't resize the brass, the Nosler box reads : 357 partition for hand gun velocities

Does it still chamber in the gun? If so, don't worry about it. I have a few bullets I load of various calibers that do that in new brass. Just lets me know it's a snug fit.

"bulges" as in seating a bullet is ruining a case, or "bulges" as in you can see the outline of the bullet's heel in the sidewalls of the brass, but the loaded cartridge drops perfectly into the chamber, or a case gage?

If you have a slight bulge but still chambers then your good to go. You may have to flare out the brass a bit more since they are new. Also when seating the bullet try to have the bullet as straight as possible. That can lessen the bulge a bit since the bullet is not seating in a slight side way position.

What is the diameter of the bullet?

I did not find Nosler 180 Grains on the web site

I did see 180 Grain .10MM/ .40 cal bullets....

Did someone swap bullets into the wrong box?

If you see the heel outline only half-way or less around the case, most likely the bullet is not straight when it goes into the case as mentioned above.
Simply holding the bullet straight when it starts into the case may not be enough.
You may need a different bullet seater stem to match the bullet nose shape (for round nose, flat nose, etc) to get the bullets to press in straight.
These bullets are a little longer than 158s and go deeper into the case so having them straight or not is more noticeable.

Without a picture of the round here is a guess,

The only 180 nosler I could find is meant for the 35 Remington .

They are at .358 dia. Measure them with a caliper and let us know.

These that I am talking about I used on Rams in a Contender.

I think he is reloading these



I would second resiziing the brass, maybe the case walls are thicker in the new brass

Depending on the manufacture the amount of internal taper can very. I have seated 200gr Lyman LRN bullets, very long shanks, in StarLine 38 Special brass without any issues.

these are the bullets I am using,wouldnt resizing make the brass smaller, which is already a issue?

On a bottle neck case, the expander ball would size the neck if it were too small. On straight wall cases, there is no expander ball, so it wouldn't do anything.
You need to fire form your cases. If these bullets don't chamber now, you need to pull them and resize the cases. I think your bullets are not seating straight, or else there is something wrong with the thickness of the cases or the actual diameter of the bullets. If the bullet was seating straight, it would be the thickness of the bullet plus the thickness of the case walls. They must fit. But if the bullet is not straight(which can be caused by not enough flare on the case mouth, or simply carelessness when seating the bullets) then you are adding thickness through misalignment.

[bruce381]

as said some brands of brass have thicker walls with more internal taper higher up than the case than other brands.

That bullet is very long and most likely is seating down further and as such the thicker case wall is bulging out this is a brass problem from using a very specialty boolit.

You will need to find which case brands have thinner walls that will allow this boolit to seat properly and NOT bugle case so much as to not chamber.

OR seat a little farther out till bulge disappears BUT make sure that they will still fit cylinder.

thanks for all the tips

Gently and slowly

Try gently and slowly partially resizing the loaded rounds. Only resize to the bottom of the bullet, not to the case rim. You might find that they will chamber, or that you need to go a bit deeper. Be very careful, because getting a loaded round stuck in your resizing die will be worse than dealing with a stuck case.

You can get a similar effect by using a Lee Factory Crimp Die. Many veteran reloaders scoff at them, but they do make it easier for the tyro.

Another tool that may help is a Lyman M Die instead of your current expander die. The M die provides a more concentric expansion and allows for straighter seating. I use an M Die for several of my loads, but they do work the case mouth more than a standard expander die.

Good Luck!
