124 9mm recipe

[Zachjet]

I have a stock master setup for uspsa CO. I’m getting ready to start reloading for the first time and I’m looking for a “safe” starting recipe to get started with, and build from.  
I have n320 for powder and 124g bullets from precision. I’m using a Hornady LNL and have federal and Winchester primers. 
 My gun was build by Jim at J&L and has a 5.5# DA and a little over 2# SA trigger. I don’t have a specs off hand for the hammer springs and what not. I have been playing with recoil springs and have it with a 8# in there now 

  I’ve been setting off all federal syntec/cci blazer brass ammo with no problem. Most other brands I’ll get light strikes.
 

Thanks for the help ahead of time

3.8 N320 w/ 125 gave me 131PF out of Stock 3.

Do you know what your OAL was?   Just so I have something to base off of?  
 

thanks

I have that very gun and shot Tanfoglio for years, CZ S2 these days, depending on the bullet and if they reamed the barrel, a RN 124 will have an OAL from 1.08 - 1.12”. The point is you need to learn to “plunk test” for the particular bullet you are using. There isn’t a “one size fits all” in reloading because of the variety of bullet profiles available. 
 

The load of 3.8-4.1 grains of powder is in the ball park and with that spring set up soft primers like Federal will be the most reliable. If you can’t ignite all factory brands of ammo then you will have to reload with the softest you can find. I used Federal SPP in my TF loads.

I buy federal whenever I see them

 

i should say that when I do have a light stroke… I pull the DA and it sets it off

I can't reiteratte this enough. Especially for the Tanfoglio and CZ-75 platforms.

I had light strikes on my Tanfo with 45acp loads and a lighter hammer spring. So I went up to a 20# HS and extended firing pin. Probably overkill but now it sets off both 9mm and 45acp 100%

[Zachjet]

What are your thought about the xl firing pin   I was thinking about trying it out 

[jubi351]

I use the PD firing pin and PD 14lb hammer spring and have no problems with CCI or Ginex primers. That being said, I only use Federal in matches.

I've loaded a bunch of Blue Bullet 125 TC and RNs - my Tanfos aren't reamed so I've found 1.10 is a good OAL that leaves a little room for anything out of spec.  For powders, I would recommend medium burn rate for 125 Blues, HP38, AA2, N320, etc.
