I bought a bunch of once fired (1000) Winchester range brass for re-loading for practice rounds. I may use some of the brass for carry rounds. During the cleaning and de-bulging process (using a Redding G-Rx push through die), I noticed that when I measured for case length many of the cases were below the published minimim case length of .840 (.850 max - .010 trim). Some cases were down to .832 in. I know that straight walled cases actually shrink after being fired and thus the "I don't ever trim pistol cases thing" that I read so much about.
Now I know that you want to keep a minimum of .400 seating (one caliber seating minimum). If I can maintain the minimum of .400 seating and stay within the published COAL, or the SAAMI COAL, or the COAL that I derive from my barrel, with there be a problem using this shortened brass?
I use a Lee FCD so the variances in the short case length is not an issue at this time.
Are there other things that I should be looking at using these short cases?
Firearm: H&K USPC .40 S&W FFDO (Fed Flight Deck Officer model - just means it has the LEO heavy trigger and Tru Dot night sights)
Powder: Ramshot Zip (faster) at 5.1 min to 5.7 max or Ramshot Silhouette (slower) at 6.2 min to 6.9 max (thinking more silhouette due to more powder in case) or Ramshot True Blue (slowest) at 6.3 min to 8.1 max (fullest case capacity). These are published loads for a 165gr JHP from Ramhot.
Projectile: 165gr Ranier Ballistics JHP (will use a 155gr Hornady XTP for carry and adjust accordingly)
Primer: Remington 5 1/2 SPP
COAL 1.124/1.135/1.135 or there abouts.....
I'll be loading these on a Hornady LnL AP with attached case and bullet feeder.
Cases were deprimed and cleaned using SS media. Cases were de-bulged as indicated.

Stn 3: Bullet feed
Stn 4: Seat
Stn 5: Lee FCD and size check
I know about the powder check and plan to do so visually. Although I do have a RCBS Lock Out die, unless I do the seat and crimp in one station, I can not use it if I use the bullet feed die so I will visually check each case for charge.
TIA
