9mm help
 
Trying to get my COL set. Right now I'm at 1.125 with a 124 gr FMJ RN. I've looked in both my manuals and the measurements differ a lot. One says max OAL 1.162... The other lists 1.142 as a min OAL. But there tested data says 1.135.... Slightly confused.

1.169 is MAX if you're at 1.125 you should be fine

Based on my materials your around is 1.15... You don't want to go below min or out could build pressures.. I like to use this site and cross check with my manuals..

9mm oal...
 
:)The difference that you are getting in OAL (Overall Length) is due to the different ogive in different Mfg. bullets.

In general you want to use the Max OAL that will fit YOUR chamber and magazine. Field strip your pistol, and do the "Drop Test" into your chamber. With the proper length and crimp, your loads should have the same "Klunk" sound as a Factory Load. The longer the better, as long as they will also fit your magazine, without binding. Yes-fill the mag. to be sure:D..Bill.

One of the easiest ways to set oal is to put a factory round of the same bullet weight and configuration in the shell holder and adjust to the factory length.

Lotsa folks get their panties all wadded up over oal, when the only thing you really need to worry about is not seating shorter than minimum, and not seating too long to feed through the magazine.

I've had really good luck loading to factory ammo length. It works fro them, and so far it has worked for me.:)

As stated, different bullets from different manufacturers have different profiles. Different OAL for different bullets is to be expected. Just because one set of data uses one OAL and other data uses a different OAL means nothing. What specific powder and charge weight is specified. All this proves is you must work up a safe load using your specific components and YOUR gun.

okay, one more question.. anyone know a good powder for the 124gr bullets? for 115 i was gonna use 231 but when i looked up the 124 it only listed WSF.. is there any other data i can look at or powders that you know would still work??
