PCC PF vs Pistol PF

19 posts in this topic

Has anyone measured and compared the MV and PF between their minor pistol load and the same load in their PCC? I'd be curious to know the load, PF in both pistol and PCC (including barrel length).

 

Thanks!

Hello: Depending on the pistol and PCC barrel lengths etc. it is between 10-20PF difference. So if your pistol is 130PF your PCC will be about 148PF. That is what the difference is on my pistol loads and my 16" PCC. I have separate loads for each. Thanks, Eric

147 gr Xtreme RN over 3.5 gr N-320

 

Glock 34 > 135 PF

 

PSA PCC (16") > 147 PF

 

Reduced the load by 0.5 gr for new PCC load at 132 PF

About the same for me. My 130pf PCC loads only make 120 in a Glock 34. I'm loading seperate minor ammo for the two. My PCC is an 10.5" SBR.

My experience mirror's Eric's exactly.  For my minor 9mm loads through a 5.25-inch XDM, I use

 

124 Montana Gold CMJ

4.8 grains CFE Pistol

1.154 OAL

Winchester small pistol primer

= 1050 fps = 130.2 PF

 

In my 16-inch PSA AR-9 this load produced a velocity of 1193 fps and a 147.9 PF!

 

I've reduced the OAL to 1.10 and the powder load to 4.3 grains of CFE pistol to drop the PCC velocity to 1085 fps producing a 135.4.PF.  I may drop the load another 0.2 grains and see what that does.

I had more extreme results with my pistol load using CFE Pistol. My 147's were pushing 133PF out of the pistol but out of the rifle it was pushing 167PF. This is coming from a G17 to a 16" rifle.

132 PF out of my 16" PCC is about 115 PF out of a 5" pistol.

My 147gr Production loads go 130pf out of my pair of CZ Shadows and 147pf out of my 16" PCC.

From a 5" barrelled pistol to a 16" barrelled carbine I gain about 10pf out of my loads. Rounds go from 880fps in my pistola to 910 in my carbine.

That's by far the largest jump ive ever heard of

It would seem to me it would be less complicated to use the pistol load in both.  That way you would only need to load one for both.  I doubt if the average jump in the PF would make the PCC much harder, if any, to shoot well with.

In my case, by dropping from PF 147 (pistol loads) to PF 132 (dedicated PCC loads) I could tell a good difference.  Enough to make it worthwhile to set up a second toolhead.

 

I'm still running a birdcage so if I ever pony up for a comp, I may need to revisit.

Are you just talking dot movement or actually feeling the difference in recoil.  If that makes sense....

Both.  I still have some dot movement but not nearly as much with the reduced power loads.  And recoil decrease to .22 LR levels.  With hotter loads my PCC had more recoil than my .223 match gun.

What was your load with CFE?

Is there a minimum PF for PCC?

Posted (edited)

Yes, per USPSA Appendix D8 the minimum PF for PCC is 125 which is considered "minor.".  That is the same as for Production, Carry Optics and minor in Limited, L10 and SS.

 

There is no minimum PF for Steel Challenge.

I am actually intentionally shooting hotter ammo to see if the comp I just put on the barrel can be made to work.  The jury is still out on that, but it is at least louder and less of an issue for the RO to pick up my shots...
