need help with sizing 9mm brass

[retired]

ok,
shooting lead or plated bullets require the bullets to be slightly over sized.
its how lead works.
the lee fcd RUINS the bullets. IT RESIZES the case with the bullet in it...it sized he bullet at the same time to a smaller dia than desired.
great with a jacketed bullet if you like that much crimp.
ruins lead bullets.

What's your OAL...? I load Berry bullets at 1.150 , from the picture it looks to long... And yes get a Lee factory crimp die and use it only enough to remove the bell on the case.. Trust me on the Lee factory crimp die it's worth the $15 bucks or whatever , then you don't have to keep adjusting your sizing die , Especially if you just loading for one pistol...

Remember as you seat bullets deeper in 9mm it raises pressure... The COAL I use is because I load Berry bullets like lead bullets..... Are you loading from a manual or just guessing..? If you don't understand exactly what your doing , STOP... I load thousands of 9mm and can answer just about any questions you have... Feel free to PM me...

Terry, I believe that some of the bell on the case mouth is not removed. Also, coating could add dia to round, mixed brass will see different dia on loaded rounds. Longer OAL's on mixed brass, vs shorter can become an issue when you set the bell on the case mouth. If you used a short case to set case mouth bell, then the longer case may have a tad bit of bell left in it when you seat the bullet....taper crimp fixes all.

I varied my seating depth in .005 increments and found an OAL that shot teriffic...hard to believe the difference.

Your taper crimp die should be ordered, and from other's responses, you have already figured that out.

By now, your confidence level is low, remove barrel and use that as a gauge as another poster has suggested. Chamber dimensions are all over the map, use the barrel.

Did you run your cast bullets through a sizer or are you coating them straight from the mold?

I think those are the syntech coated bullets... I believe you can by them now...

the problem with this process, and why it is selfom used, is that you are still MOVING the bullet, while CRIMPING the case. not good.

Could be, not gonna argue that haha. It works perfectly for me so far though. Ammo comes out perfect, fits in anything, bullets arent loose. Looks and shoots just like factory ammo. I imagine ill get a crimp die one day. I got the spot on the tool heads for one, just never got thst far because of no need to. It would probably make changing to different bullets easier...

You using a progressive or single stage (I missed that)? If single get the LNL conversion, makes it easy to take out your seater die then put in your crimp die that's how I do it.

you ever wonder why that press has so many die locations ??

Yes I do resize after i powder coat and im going to check out the taper crimp die

Heres a question for you i have a few die sets for 9mm and at the bottom of the crimp die there is a stamp " 9mm - H7 or 9mm - K7 meaning ??

 

[Terry Archer]

Bullets are out of spec because of the coating?

i resize after powder coat .356 dia.

Lol Ive known its for a crimp die.

Perhaps I missed this, but suggest minimizing the size of the bell mouth... just big enough on which to set the bullet and lead it into the case. This makes removing it easier in subsequent operations.

Glad you got it fixed. I use a Lee Factory Crimp die and recommend them. I shoot mostly cast bullets and have great accuracy.
