ok,today I tried my hand at reloading 9mm. I had to change over from 357,,I managed to get things sorted out and reloaded 70 cartridges,,3 differant bullet weights. Now the problem that I have is not all of the cartridges fully seated in the chamber. They were so much larger than the chamber the slide would not even go forward all the way. Any solutions??? P.S. I'm using a dillion xl650 press
 
i would say make a dummy round to 1.100 and see if it chambers,

what bullets and weights do you have as well?
 
all home made lead cast bullets,,123gr,,127gr,,154gr,,this is my first try at reloading,,I just cant figure out why the bottom of the case would be bigger than the bullet end
 
is it range brass? - possible glocked brass.

try resizing/depriming a couple pieces of brass then try to load those into your barrel.

if they fit, then load them up with which ever bullets you want and see if they fit again.

you may have your bullet seating/crimp die to low causing the case to bulge near the bottom.

this happened with my 45acp. i wanted a tighter crimp so i lowered it and maybe every 20 rounds it would ripple the side of the case. so i backed off the seating die and never had the problem again.

EDIT: also as a curiosity, could you post pics of the bullets, or tell me the make/model of the bullet molds? those are all od weights for 9mm.
 
Maybe your crimp is coming on too soon and grabbing the lead bullet before its fully seated. This would bulge the brass below the bullet. Try backing your seating die body out a turn or two, then coming back in with the seating stem so there is little to no crimp.


Edit: I see spawn has offered the same advice in regards to his experience with 45. This is my best guess if you are using a 3 die set. Switching over to a lee 4 die set may solve it for you.
 
run them through one of dies only, for OAL consistancy. you may need to use caution, as pressures are going up. I would not go under 1.010 but depends on your gun. use a guage to drop them into. if they pass, then they should be fine. best 20 bucks i ever spent. (Lyman makes one):

could be many things...

I thought seating depth, but you are below the max

Then you said cast bullets, what is their diameter/what are you sizing them to?

154gr bullets is on the heavy side for 9mm, 147gr seems to be highest weight commonly used

what dies are you using? a lee factory crimp/final size die may be the solution you need (on a side note, 9mm doesnt really need a crimp, could be that when you are crimping, you are digging into the bullet and compressing the case to make the bottom bulge)

remember, 9mm is rimless and chamber on the case mouth, unlike the .357 magnum you are used to
 
I had a problem when I loaded .45 with truncated cone bullets.
My OAL was right, but because the top of the bullet was "missing" the bullet was not seated deeply enough and the round would not chamber.

this is also bang on! had the same issue, this is why seating depths vary so much, each bullet type is different.

the proper way to reload is to have your barrel (disassembled) nearby to test a few bullets in the chamber while seating/sizing and adjust the OAL to your gun

This is a good suggestion...especially if you're doing it for the first time. In my CZ, I have to push the bullets down to 1.030 OL.
 
Thank you for all the info,I think I managed to get a fairly good reload. OAL is 1.25,,DIA is .380,,4 grains of powder and Wolf copper plated 125 grain copper plated round nose.I also checked them all in the barrel for fit and feel.Later i'll give a range report
 
autoloaders are a bit more involved to load than revolvers.note you said some rounds didn't chamber. use brass which is all uniform in length.this makes a difference because the case headspaces on the case mouth.it is difficult to set your taper crimp when the cases are all different length.pay attention to the reloading manuals when you set your crimp,there is a min and max.too little and it won't chamber,too much and it won't headspace on the case mouth.
