Loading for my M1 Carbine, I noticed a noticeable bulge where the boolet is.
Using Lee 120gr, .309di.
I was wondering if anyone has tried to partial size the case, so as not to have the bulge.
Seems to chamber fine.

I load 110 gr. FMJ and SP using a carbide sizer, no bulge. Are you contemplating partially sizing loaded ammo? Probably not a good practice. If it fits your chamber I'd just use it "as is".
be careful what diameter bullet you use, as there are quite a few different .30 cal sizes.
slug your bore. and get what fits it.
I could be wrong but most carbide dies use a ring of that material to size the casing. The 30 carbine is a tapered case but I don't think the carbide ring in the sizer die tapers the case correctly.
I've found that by backing off the sizing die I can get rid of most of the 'coke bottle' bulge. Cartridges still chamber & function.
What FL die are you using?
Your last sentence sums it up. If they fit and function I wouldn't worry about the appearance a great deal. My loads with the Lee C309113F using Lee carbide dies show this, too. But they shoot fine. When I load Privi .307" jsp 110gr bullets there is no bulge. They shoot fine as well.Quote:

Adjusted the LEE size die out, so the 309 boolet would hold firm, without bulging the case.
Flare with the LEE charging die, and seated the boolet with a crimp to remove the flare.
Boolet is holding firm. Tapped it with a hammer.
Chambers fine.
One slight glitch.
Had to deprime in another step. LEE punch is not long enough.
Just another step. Not a real problem.
Will try it next time at the range.
Using a Lee FL die. Like Texas by God says, as long as they chamber, fire accurately and eject the bulge is of no consequence. For plinking & paper hole punching I load a mix of about every commercial HS. Most of this brass has been loaded 8 or 10 times and trimmed to length at least once. The slight 'wasp waist' doesn't seem to cause premature case failure.
You might try a different shell holder. It might give you the clearance needed for the primers to pop out.

I bet LEE would fix that problem.
You mean they are not supposed to look like that?
Mine have have looked like that for the 25 years I have been reloading 30 Carbine and still put a little hole on the near side and a big hole on the far side of a white tail doe's neck at 75 yds.
In the immortal words of Troy Laundry, "Choot 'em".
The 30 Carbine in not a straight walled case, it's a tapered case. In my experience loading with cast, it's pretty common to have a "slightly hourglass" shaped loaded round. I would not partial size, and as long as they chamber and function you should be fine.
Took it out this weekend.
Shot fine.
I did have one problem. Didn't happen all the time.
First round would not chamber.
Could be the mag.
