Looking for a PCC load with N320 and a 124 grain jacketed bullet

[RangerTrace]

Just in case you are not following the JP5 thread, I'm looking for a PCC load that works with N320 and a 124 grain jacketed bullet.  If it makes power factor in a carbine and pistol, that is a bonus.

 

My pistol load has been a 147 grain JHP over 3.5 grains of N320 to 1.125".  It makes PF easily out of pistols and is extremely soft/flat out of the JP5.  Functions 100%, but is only 800 FPS.  To be specific, the load was 910 FPS out of my P320 and 800 FPS out of the JP5.  I assume any load with N320 will be similar.

With a 124 PD JHP and 3.8 N320 I get 126 PF in the JP-5. 132 PF with 4.0 N320. I would not us N320 with the JP-5 and heavy (147gr) jacketed bullets. You should use a slower powder with the heavier bullet in a PCC. By the way, all my loads 147, 124 and 115 have been about 5 PF less in the JP-5 than I had in my GMR-15 for the same loads.

Great information.  Thank you!

Any reason why you suggest not using 147 gr with N320? I use polymer coated with about 3gr and get about 135pf in mt GMR15. I would be interested to understand your comment. Thank you. 
I did try a slower powder (maybe too slow, had Lovex 37.01 for my open gun) but still prefered the N320.

A faster powder with heavy bullet will sometimes cause a squib. The JP-5 is about 5 PF less the my GMR-15 with the same load. I loaded a coated lead 147gr with 3.0gr of N320 and got 133pf. You would probably need at least 3.3 to be safe with a jacked bullet.

Check JP video for PCC loads. They hand several barrels returned with multiple bullets in the barrel.

Wonder if that's a result of the fluted chamber in the JP5, if you've looked those flutes go into the bore so it's probably leaking from the start.

Are coated bullets good for shooting out of a PCC or not? 

 

I read that some people using them in custom loads and some people are shooting 130gr Federal Syntech.  I'm worried about the plastic coating eroding before it exits the barrel and lead building up on the inside and on the comp.

have yall slugged the barrels?  a more open barrel could lose some power.

 

thing is that while it will tell you the cause for the slower projectiles

it offers no direct solution to the issue...

If possible, I'd load a bit longer and add powder and use the pistol to evaluate for pressure signs.

I use 4.0 gr. of N320 with the HAP 125 gr. bullet.  Works well for my Glock 34 and my PCC (Taccom 10/16 barrel).

What OAL do you use with the HAPs?

I use 1.125" for the 125 gr. HAP rounds for all my guns.

[sigh] Switched back to using 5.2 gr. of N350 with 115 gr. HAP bullets.  Just ran smoother with my two guns.

Running 3.8 N320,  1.135, MG 124 JHP at 130ish  PF. Running in both a gmr15 and gen 3 Sig MPX,  both run them fine.

3.9 N320, 1.135 X-Treme bullets  135 JHP. got 136 PF, running in Sig MPX Gen2, no problem at all

124gr. RMR FP Match Winner - 4gr. -VV  N320 @ 1.125" gives me just about 130 PF in TSO and GMR-15, haven't clocked in in JP-5 - probably a little slower.  Good all around load, falling steel, that sort of thing.

Apparently coated bullets will lead up the compensator faster than jacketed/plated bullets.

[telligentgunner]

I have shot almost a case of 1000 coated bullets through 2 different PCCs and both comps are caked.  It even effected accuracy in my JP-5.

 

I will never use coated bullets in a PCC ever again.  I'm even hesitant to use Federal Syntech PCC ammo, but Josh Froelich uses it a lot. 

 

If anyone wants to buy the remaining 900 rounds of coated ammo I have left, let me know.

Looks like I better source some copper plated/jacketed bullets

Finally made it to the range with my chrono to test my new 124 grain load in the JP5.  It's an RMR 124 grain truncated cone Matchwinner over 4.2 grains of N320 to 1.125".  Not sure what the magic is with the 124s vs. 147s, but the load made 130PF out of the JP5 and my P320.  The 147s were not even close to making PF out of the JP5.

124 PD v2  with 3.9 N320   runs perfect in MPX  as well as my handguns

For whatever reason, my 147 grain load was about 150 FPS slower out of the JP5 than the P320.  I expected something similar with the 124s, but was pleasantly surprised.  I was also able to put the original lock piece back in as well.
