Hello Guys

I am currently using a Dillon 650, with dillon dies for 9mm. All of my rloads look nice, perfect seating and crimp. The problem that I am having and can not fix is that my reloads look like a coke bottle.d The bottum and tops are wider the then middle. I wqs able to reduce the top to match the middle, but I can not get ride of the bulge at the bottom. This bulge cause jams on most of my guns????????????

how do you get rid of that 9mm BULGE. I have spent way to much money on my supplies to just give up.
 
Check out the thread mentioned above!

If your gun is jamming, you may need to seat the bullet abit deeper! However check your reloading manual for the min oal. for you load!

The coke bottle shape is normal though.

You don't want the "top to match the middle", and if you've adjusted your dies to do this (as in raising the die in the press), that's why the bulge is causing jams.

Set the die per instructions (typically touching or just touching the shellplate with a case being sized) - the "bulge" will become smaller and your loads should start working fine. The coke-bottle thing doesn't matter.

if you really want to get rid of it, research "Lee factory crimp die".
 
The 9mm is a tapered case and will not be straight even in factory loads.
Perhaps you are trying to correct a " problem " that is not an issue.

I agree with the above to adjust the dies as per specs and make sure that the OAL is
correct & you should be okay.
 
The "Coke bottle" shape is normal for 9mm reloads, at least with the Dillon dies I use. The sizing die should be screwed all the way down to the shellplate in the up position, and then backed off slightly to protect the carbide insert from possible impact.

Take the barrel out of your pistol. Does a resized case drop freely all the way into the chamber? If so, the case has been resized correctly.

Loaded rounds should do the same thing. If not, the bullets are seated too far out or you need more crimp.
 
The reloads that I am making are working fine (well 1 jam out of every 100 or 200) out of my glock 17 and my friends glock 17. the problem I am having is on my m&p 9, it seems that i am getting a jam every 20 or so. I have the resizing die touching the shell plate, and the lenght seating is as per OAL. the bullets look good, but its the bulge at the bottom is causing the jams I think. I have been using the barrel of 1 of my glocks to check the size of the bullets, and when I tip the barrel upside down to remove the bullet, the bullets does not fall out of the barrel easily (I was told that when I turn the barrel the bullets should fall out without any help, but gravity? is it the bulge at the bottom causing this?? I cant see the top little bulge causing the problem as the bullets goes in the barrel very easily
 
If they are not dropping out of the stripped barrel, you may have a problem. What weight/type of bullet are you using? What's the OAL?
 
Does a sized case with no bullet drop in and out freely? What about in your M&P? This determines whether or not there is a problem with sizing.

The OAL given in your reloading manual may be excessive for your guns. You may need to adjust it to fit the chamber of your gun.
 
Industry calls it SPC (Statistical Predicable Process Control).
Cleaned brass with a good case cleaning process then well lubed brass that is thoroughly inspected for defects in a brightly lighted area will decreased the percentage amount of scrap your making. Use a case checker after you've finished taking out any questionable suspect cartridges and pulling them apart disposing of the components accordingly.
You may find you’re far sighted and need glasses or a magnifying glass for inspection purposes but above all enjoy the past time.

thanks guys for all of the info. Tjhaile I like your idea, i will drop a resized cartride into the barrle of both the glock amd M&p and see how easily they slide in and out. i will also check the overcrimping issue.

I will check these issues tonight and get back to you all.

At first i was kinda of scared to invest over $2500 in all the equipment and dies, but then I remembered that I was not alone in this I always have CGNers behind me.

Thanks
