mellino19 Posted February 12, 2019 Share Posted February 12, 2019 (edited) Hi all, I'm looking to change up my PCC loads for various performance aspects and partially going with the herd. I hear of many PCC guys going over to 124gr loads over 147gr. I know buffer and everything else matters but I'm concerned with reloading for now. I'm currently running 3.3grs Titegroup with Xtreme 147gr RN and a 1.15" OAL. No idea what FPS or PF (no chrono). I'd like something that runs a little more quickly. The main reason I run this formula is because it's what I use in my CO guns and my PCC is sub-MOA accurate with them but a tad sluggish cycling. I ordered 1000 125gr RN Ibejiheads and was looking for some tips from guys running painted bullets on PCC platform. The Hodgdon site shows a starting load of 3.6grs with a max of 4.0grs but a OAL of 1.125 for 125gr rounds and for 124gr rounds the OAL is a dash longer and max charge is a whopping 0.1grs higher. These are also pistol load data points so I don't know how much should change for a PCC. I dropped an Ibeji into my press and without touching anything I get 1.14" OAL. I figure with a PCC this won't be much of an issue and was thinking of doing some load development with 3.6, 3.7, and 3.8 to see how they all perform. Any recommendations on loads or am I pretty much heading the right direction? I'm running a 14.5" AND a 16" upper if that matters. Thanks!

AHI Posted February 12, 2019 Share Posted February 12, 2019 Your length may be to long most (not all) pcc require shorter ammo. mine for example with a SNS 125 RN 1.120 do a plunk test before you load up a bunch of ammo. Next start at 3.0 powder charge you may be pleasantly surprised at how it shoots. You may end up at the same charge you are using for your 147.

motosapiens Posted February 12, 2019 Share Posted February 12, 2019 Painted? you mean polymer-coated, I assume.... many of the coated bullets are fatter in the ogive than plated, so I recommend loading one up and dropping it into your barrel to make sure it doesn't interfere with the rifling. If it does, put it back in your seating die and push it .01 deeper and try again. continue until you get a round that plunks reliably. most anything should make pf in a 14" barrel.

Coated, yes, sorry. My buddy always calls them painted, bad habit I picked up haha. Does the plunk test do the same as using a case gauge or is this different?

HoMiE Posted February 12, 2019 Share Posted February 12, 2019 For 14.5” and 16”, most of my loads are 0.3-0.4 grains less than my pistol loads. For fast burning TG, I’d probably drop it 0.3 and chrono from there. Link to comment Share on other sites More sharing options...
AHI Posted February 12, 2019 Share Posted February 12, 2019 plunk test is to find the max oal in your chamber case gauge is to check the quality of your ammo Link to comment Share on other sites More sharing options...

You only need to plunk test once with a particular bullet to find out the max length for that bullet in your gun. Link to comment Share on other sites More sharing options...
RocketRyan Posted February 13, 2019 Share Posted February 13, 2019 I'm running 125gr @1.100 with 3.4gr of Titegroup and it makes 136 power factor out of a JP 14.5". I would say you are very close and would chrono your load (Ask around to borrow one at your local club). Link to comment Share on other sites More sharing options...
goldfish Posted February 13, 2019 Share Posted February 13, 2019 Monitor your reloading dies for built up as the coating does sometimes flake off and may cause some inconsistency in your loads. Link to comment Share on other sites More sharing options...

Have loaded tens of thousands of sns, bayou, eagleson ,precision, etc and never experienced this. I guess you could have this if you dies aren't set up correctly.Or poor quality coated bullets. Now old style lead wax lubed bullets that's an entirely different story. Edited February 14, 2019 by AHI Link to comment Share on other sites More sharing options...
