I think I am dialed and ready to go as far as reloading on a lee classic turret press. I have once fired brass and would like to start loading 125gr lead fn bullets. my manual says overal length should be 29,69mm. my dummy rounds are at 29,60mm and look good from my limited experience.

i am loading for a 92fs and would like some advice before i start so i dont waste any material. what length should i be at and what may i be missing?any suggestions please?

You will get more advise if you refer to OAL in inches around here.

Sorry! I am new.

OAL= overall length?

1.167 inches on the dummy round.
1.166 inches other dummy round

I am not quite sure where I am supposed to be length wise.

It depends on the bullet. So many profiles out there.

the box says PROFILE: simi wad cutter
WEIGHT: 125 gr
SIZED: 356
CALIBER: 9mm/38 Super

both dummy rounds cycled through the magazine and ejected from the chamber except for one time, and i think its because i didnt rack it hard enough.

manual says overall length should be 29,69mm ... 92fs ... PROFILE: semi wad cutter ... what length should it be at?
Using the OAL in the manual won't ensure the finished rounds will function reliably in YOUR pistol (especially if you are using a different nose profile bullet like a SWC and if the manual is using FMJ/RN) as typically a test fixture is used to measure chamber pressures and not an actual pistol.

To determine the Max OAL and working OAL:

- Take the barrel out of the pistol and hold it upright

- Drop some resized cases in the chamber (they should drop in freely)

- Using a dummy round (no powder, no primer), starting at SAAMI max OAL of 1.169" (29.69mm) and applying a taper crimp of 0.021" (0.54mm) to the diameter of the bullet, incrementally decrease the OAL until the dummy round drops in freely and spin without hitting the rifling - This is your Max OAL

- Once you determined the Max OAL, you need to function check to see if it will reliably feed from the magazine. Incrementally decrease the OAL until the dummy round feeds/chambers reliably from the magazine when you manually release the slide. Sometimes, this working OAL may be the same as Max OAL; but usually, it is shorter than Max OAL.

- Once you determined the working OAL, then conduct a full powder workup from start to max charge to first identify the powder charge that will start to reliably cycle the slide and extract/eject the spent cases and second identify the charges that will produce accurate shot groups. Usually accuracy will improve as powder charges approach high-to-near max load data but many faster burning powders than Unique/Universal will produce accuracy at mid-to-high range load data and plateau towards the max charge.

Thank You. This helps very much.

I have done a barrel check...good

Chamber slide check ...good

I am anxious to begin but want to be "good to go" before jumping in.

I have a lee classic turret with the factory crimp die. HOW DO I MEASURE THE CRIMP ON THE FINISHED ROUND?

.356" is way undersized for your barrel. You'll get severe leading.

Can I just clean the barrel when I am done shooting?

Yes, although you will find the task a bit challenging. The chrome lining helps with that, however.

IMHO, the Lee FCD was meant for jacketed diameter bullets sized .355" to ensure finished rounds work with SAAMI spec chambers but when using larger sized .356" diameter lead bullets, it may post-size the round and reduce the diameter of the bullet, decreasing the bullet-to-barrel fit (especially for Beretta 92FS barrel which is known to be oversized) which will increase leading as 918v posted.

I usually recommend FCD not be used with lead bullets. I use Lee dies and seat the bullet and taper crimp in the same step. I just loaded two SWC rounds for the picture and used .377" (9.57mm) taper crimp without shaving the lead from the side of the bullets.

Below is a picture of Missouri 9mm 125 gr SWC (Semi Wad Cutter) bullet sized at .356". The round on the left shows 1.090" (27.68mm) OAL which is the Max OAL that will work with KKM aftermarket barrel for Glock and round on the right shows 1.070" (27.17mm) OAL which is the Max OAL that will work with Lone Wolf barrel due to faster start of rifling. My working OAL is 1.070" and this OAL will also reliably feed/chamber in the KKM barrel as well. If I want greater accuracy load for the KKM barrel, I would run the longer OAL.

918v Are you are on another reloading forum?

I was just reading about slugging a 92fs barrel and 918v was on there.

Reading the post about slugging the 92fs said the barrel sizes may vary from .354 to .358.
I bought these at a local gun shop and the gunsmith said they should be ok. If i get leading I will take them back. I am pretty sure he isnt going to have anything left.

Maybe the gun show in two weeks might have some FMJ.

That is what my bullets look like. should the blue ring be below the top of the case?

just looked up some load date in reloading for handgunners

it calls for a 1.13" for 125 lrn with titegroup powder

need to seat them deeper. also calls for more grains of powder

Yes, I'm everywhere but not at the same time.

I owned three M9s. All had bores greater than. 356". They had .359"/.360" throats and I shot .359" bullets through them to avoid leading. My best load was a .359" Lasercast 125gr TCFP over 3.8grs of 231 @ 1.040" OAL. It grouped about .75" at 15 yards from a benchrest.

Ooops, 918v posted while I typed.

trextrex1029, we have discussed leading issues with oversized barrels on multiple threads before.

As 918v posted, Beretta 92FS barrels are larger than typical .355"-.356" groove diameter of factory and match barrels, which results in increased leading due to bullet being undersized for the barrel.

Many bullet casters will offer different sizing of their bullets, often at little or no extra cost.

If your leading issue cannot be resolved to your satisfaction, you could consider using copper plated bullets like Berry's, Rainier, Power Bond, Speer TMJ, X-Treme - http://www.tjconevera.com/bullets.html

Or just get some Missouri Cowboy #2 38 Special bullets. They are 12 BHN and will obturate well at 9mm starting load pressures. They won't lead.

918v, good suggestion! The larger diameter and softer lead alloy will definitely help the bullet seal with the barrel better - http://www.missouribullet.com/details.php?prodId=50&category=5&secondary=9&keywords=

I do not know where the lube ring is on the bullets you have but if they are comparable with the SWC bullet in my picture, the lube ring should be below the case mouth and not be visible.

done. Thank you.

Guess I should try to take these others back. Dont think he will take them. May be I can unload them somewhere. Any suggestions?

There is a good article on loading the 9mm Luger in the Feb 2013 (latest) issue of Handloader magazine.
