Load for short barrel PCCs

[Rob5r]

I'm looking for a 135 power factor load for my 5.5" bbl GMR-15.  I see the most popular bullet weight from the 2021 USPSA World Championship was 124/125gr.  A lot of people are telling me that coated bullets will foul the comp pretty fast.  But that's not an issue for me.  I have my sights on a 125gr Blue Bullet, OAL 1.014 and Tite Group.  Need to be legal for IDPA.

Fast powder will work the same in your 5.5" barrel GMR as a 5.5" pistol.  Tight Group will work fine.  I was using 4.2 grains of N320.  I think 4 grains of TG would be a good place to start.

I have 2 short barrel PCC's 5" Taccom barrels and a 13" Taccom.  I run 124gr plated bullets from Everglades ammo with 3.3gr of Titegroup with a 1.10 OAL.  I don't recall the PF, but it functions well in all my guns, not just my PCC's.

124 PD  with 4-4.1 N320  shoots perfect pcc or handgun

Im running 124 gr Xtreme CMJs over 3.5 gr of titegroup.  I'm running a 16" JP barrel however.

4grs of sport pistol, 124-125 bullet, normally 1040fps in my 5.5 taccom barrel

I’ve been running the Taccom 5” with shroud using BBI coated bullets for a couple years now and still have never cleaned the shroud/comp. The inside of the shroud has a very thin layer of fouling, but nothing has gunked up.

147g FMJ 3.0g Titegroup 1.1" OAL made 140 PF on my Taccom ULW-B barrel: 5.25" barrel with shroud. Funny enough - Same load makes same PF with coated bullets out of my new JP-5.

I run a Taccom ULW 5.5” barrel

I use either Berry’s or Extreme plated bullets, 3.9gr of TiteGroup, 1.110 OAL

Take this for what it's worth as I load for Steel Challenge and don't need to make PF.  In my load testing and development over the years I found the following:

 

 

 

The PC Bullet (RNFP) is a poly-coated and the Everglades (RN) is plated.  I know it's not as popular but Clays is really soft shooting and the 147gr. gets me to minor with no pressure spikes or anything.  My AR-V has the Taccom XLW barrel so the effective rifling is 5.25" which is the same as my Canik TP9 SFx.

I shoot Federal Syntech Action Pistol out of my CMMG Banshee with a 5 inch barrel. Never had an issue.

What bullet weight for this charge?  I have 2 pounds of e3 I want to try out.

For my pccs &pistols, I use 4.2 Gr Tight group over a 124 gr Everglades plated bullet. 

 

Works great in Pistols and carbines.
