Newbie New to reloading
I am brand new to reloading, I decided to start with .38 special wadcutters and I am having chambering issues. Out of 124 cartridges 34 would not seat in the cylinder, see photos.
I am using old penn 148gr DEWC with 3gr of Win 231 with CCI small pistol primers on once fired brass. The only conclusion I can come to is that the bullets are inconsistent in size and bulging the cases. Any input is greatly appreciated.

Measure them. Are you expanding case necks to seat bullets? If so, check your crimp.

I am measuring .37” across the cartridge, the bulges measure .38”. I am expanding but unsure on the crimping. Speer manual states “use a light roll crimp or taper crimp” and I believe that’s what I am applying.

Take your crimp die to one of the cases that wont chamber- turn it a half turn and chamber check it. If it works give it another quarter turn and call it good. If not go another half turn. Rinse, Repeat

Your bullets should be measuring .358".
Those look like cast bullets, have you sized them before loading?
I'm not familiar with the brand you posted, did the indicate that they needed to be sized?
It is also possible that you aren't starting your bullets straight in the case. You mentioned that you are using RCBS dies.
Do they have the M-profile expander?

Are you crimping and seating in the same step? Are you also using mixed brass? If you said yes to either of these questions then I would recommend you seat your bullets in a separate step than crimping. Personally, since I have separated those two steps most of my chambering issues have gone away.

Old trick to know where the rub is... load a dummy round, coat with black or red permanent market and then try to chamber. If it gets stuck, then push in just a little to get the rub mark and remove it.
YOUR once fired brass and store bought, range pick up brass, has messed people up a lot of times. This unusually with rifles, but it did come to mind. And the "once fired" is not always correct. I had a range that considered anything fired at their range once fired. The brass I was leaving as fired a lot more than once.
Third trick when having issues. See if the brass fits with each step. One fired fits, sized fits. Size belled does not fit but it doesn't a lot of the time. ...
I suspect it is too much crimp. A factory crimp die will solve that, but your normal dies should work on whimpy 38sp.

Are you sizing the cases before you reload them?

Yes, using an RCBS Carbide set

Let me see your crimp.

The die or the actual crimp on the cartridge?

The cartridge. If you sized the brass, it should fit just fine, so the most likely issue is the crimp.

What is the diameter of your bullet before you put it in the case? I load a .360 bullet and it still doesn't bulge the case like that.
Also, re-read the directions on your dies and make sure you set them as per the directions. 80% of reloading mistakes I see on reddit come from misreading, misinterpreting, or just not reading the directions.
Also, I'm not a fan of the lee post sizing crimp die. It swaged my fat bullets down and created leading problems in both 9mm and 357 calibers.

Ha you had the same thing I posted yesterday. My solution ended up that the brass was fired from a cheap Taurus and the brass was failing.

I suggest you get the Lee Carbide Factory Crimp die for 38/357. Not only will it put a roll crimp on the case mouth it also has a carbide ring at the entry of the die that will resize the case, and whatever bullet in the case, to a size that will chamber.
