I will try to get some loaded up this week, and shoot next weekend assuming the weather is good, so I should be able to give you some idea of how it does with 90g tnt's, and 95g Amax I will start using the H335 for my next round of load testing, I have seen the results of what has been said on here, with the N133 powder, Max I can get in a case is 27.1g and it is mildly compressed, My last trip to the range I tested Sierra 85g varminters with n133 powder and best I could get with it was 1777 fps with a load of 26.1g of powder. Best velocity was with CCI 450 primers, but I did try the same loading with Remington Bench rest primers and got close within about 30fps of the 450 primers, and the accuracy was excellet with the BR primers, sub .5 moa I will try 3 more loadings with the n133 and the 85g bullets, 26.5g, 26.9g, and 27.1g, I have these loaded up just waiting to go to the range, after these I will have enough fireformed brass, and plan to start load testing the h335, I do not have the Crimp die yet so all of these tests are uncrimped, I do think I would get a little more velocity out of them if they were crimped. I'm sure you meant 2,777 feet per second velocity with the 85 grain SIE loads using N133 powder with non fire-formed brass cases... Most of the 6.5mm PCC end users are getting ~ 3,000 feet per second with the same pills using H335 powder... Yes, you are correct I meant 2777 fps, I just started with the n133 to see what it would do, I had heard from guys at my range that like it for 223, and I have a lot more of it than the H335, Looking forward to getting over 3000 fps out of the H335. It should be Interesting how N133 does using fire-formed brass loads...It may get fairly close to H335 in velocity with the added benefit of excellent accuracy especially using bench rest style primers and/or magnum rifle primer (use caution with magnum primers combined with "stick" or extruded type powders as you may develop pressure spikes). Keep us updated with your load data developments using N133 powder with your 6.5mm PCC rifle, I really like that you are getting sub .5 MOA groups with certain loads you have tried so far with match rifle primers and N133 powder... Thanks. |

Went to the range today and tried more loads with the N133, 3 with CCI 450 primers, and 3 with Rem Benchrest primers, these were with non fireformed brass, sierra 85g, COL 2.275, Temp 80 deg, Humidity 66%, 5 rounds with each load.
CCI 450 26.7g - avg vel- 2790 fps, group size .75" 26.9g - avg vel - 2775 fps, group size .80" 27.1g - avg vel -2813 fps, group size 1.38" (remove 1 flyer and group would be .60") Rem Bench Rest 26.7g - Velocity unknown (crono problem), group size 1.22" 26.9g - Avg Vel - 2799 fps, group size .80" (4 shot group was .50") 27.1g - avg vel - 2779 fps, group size 1.05" (3 shot group was .20") I sorted brass by weight, not sure why the 26.9g CCI load was slower than the 26.7g load, and the 27.1g Rem BR load was slower than the 26.9g load, There were no pressure signs on any of them. I will lower these about 5% and try again when I can crimp them. I will start loading with the H335 next and see what this will do in my 24" barrel |

Velocity seems quite good and pretty consistent for the most part as does accuracy...All should Improve once you get your factory crimp die in hand. Thanks again. |

once I get the crimp die, I will see how it does with the fire formed brass, I did try one round of fire formed brass and it did not seem like I gained any noticeable capacity, maybe due to how poorly the n133 settles in the case, I might be able to get just under 1 grain more powder, but the crimping should allow the pressure to build up enough that I should see a decent boost in velocity just from that and the consistency of bullet release should improve accuracy.
I have 2 other new guns that I just started reloading for so I may just focus on them (7mm-08, & 6.5 Creedmoor), until I get the crimp Die for the 6.5 PCC. I will agree, I am getting better velocity than expected with the N133 based on what others had experienced, maybe the 24" barrel is helping. I have not tried the 95g V-max since the first round but I did get 2781 fps with 25g of N133 on that first round which was better than what I have read others are getting with the H335 on that pill without any pressure signs. |

View Quote Excellent, both are super rounds BTW, 2,781 feet per second with the 95gr. V-Max in the 6.5mm PCC for a starter load using N133 is a excellent velocity...I would guess it may be possible for you to break 2,900 feet per second with your load development with the 95gr. Hornady V-Max...Good luck, stay safe and keep us posted. |

Update on Lee Precision Die Sets & Factory Crimp Dies:
Received a update from the factory Rep. today, the FCD's will be shipping this Friday the 6th of June. The Die Sets should be shipping by the week of 16th of June according to the factory Rep. The Die Sets would have shipped about the same time as the FCD's but someone who was not ready for prime time became reading dysfunctional and made the die bodies to 6.5mm PPC dims Instead of the 6.5mm PCC of course, after sending them several fired cases, dummy rounds, prints and making several notations in the order form of the parent case...and they still managed to FUCK IT UP !!! There is of course a HUGE FUCKING DIFFEREANCE between the two parent cartridges if one were to put each- other side by side, and alas they somehow still FUCKED IT UP ! This only took seven fucking months of waiting to get to my order, so they can manage to delay it for at least another two to three weeks... Sorry, I have to vent guys ! I will of course (as always, since very few people nowadays have a clue on what the FUCK they are doing anymore) double check all dims on the dies once I get them...before they are shipped out. Thanks fellas. |

To be fair to Lee Precision, they have never taken this long on a order and they previously were on point with shipping and product quality...
It so happens they dropped the ball with my order as they are so far behind on orders in general... |
|

OK, some good news finally...I just received shipping notification that the Factory Crimp Dies are shipping !
Now, for those that have ordered FCD's like SpinLite1, they will ship out this Tuesday or Wednesday the latest. I will of course (as always) check them for proper function before they are shipped out to you... Have a great day everyone. |

OK fellas,
The Lee Precision Factory Crimp Dies came in, they will be shipped out tomorrow, ASAP. Today I will double check to make sure they are to spec./are delivering a good solid crimp on the case(s)/case necks... Those that have the dies and barrel already will get there FCD's first, or are just waiting on the FCD's will get them shipped out first. Those that are waiting for the Die Sets and/or Barrel(s) will get everything shipped all at once (does not make sense to ship every piece separately and risk lost packages and added cost and time, etc.). With any luck, we will get the Lee Rifle Die Sets in another week or so, fingers crossed... Thanks. |

With this difference, would that mean adding .006"/.007" to each of the three gauge's printed dimensions above, and also machining each gauges shoulder the datum line is located on to 32 degrees would be able to check / measure the initial headspace and check / measure yearly the headspace (just the bolt-face to datum line headspace dimensions) for 6.5 PCC? If not can you touch on the topic what sufficient measurements will be from the bolt-face to the datum line for 6.5 PCC. I'm wanting to figure out what works due to being very interested in building a 20" SAM-R variant AR15, but chambered for 6.5 PCC. Also, I'd like to be able to gauge the rifle's headspace due to the setup is being built as a battle rifle for common defense first, and for hunting medium / medium-large game second. |

SpinLite1,
Your Lee Precsion FCD was shipped, you should be getting it within 2-5 buiness days...[It says this Monday but...who knows] Thanks. |

great, I was waiting on them before I did any more testing. Hopefully it will come today, if it does I can load some up and maybe go tomorrow to the range.
Thanks |

Just got off the phone with Lee Precision (again) regarding the delivery of 6.5mm PCC Die Sets, [and drum roll please...] they said delivery will be confirmed
for Thursday June 19, 2014 from the factory....Finally, It only took them better part of 8 months, and a lot of high blood pressure, heartburn, and endless phone calls back and forth... So with that time frame in hand, all the gents waiting for their die sets will have their die sets shipped to them by June 26/27, 2014. Thanks. |

Got my Lee FC Die this morning, I will try to get some loaded up this week and hopefully go to the range this coming weekend.

Thanks Biggdawg, I was going to suggest a starting load of 24.0 grs. using H335 powder and then work your way up... |

Got the .300 BLK mags and was a bit disappointed, when I measured the COL It was only 2.275" (max.), definite bummer...hopefully
they will run great for everyone who gets a chance to try them out in the field, etc. The .300 BLK magazines will be shipped out Monday, Thanks. |

That's too bad. PRI 6.8's with 5.56 follower is still the best I've tried.

hilljack,
Have you bent the feed lips to match the case? I get some cases that load just fine and others that rattle around a bit and don't lock in as well. Otherwise they feed a lot better than standard 5.56mm mags, let alone the PRi 5.56mm mags. No jams, no FTFs, or FTEs. Will probably be completing my new testing with H335 and Sierra 85 gr HP Varminters today. My original testing was done with 55114 PSI, which was the original loading prior to the laboratory pressure testing, which shows 62,000 PSI. Now I have amped it up a bit, just about 2 full gr more, which makes them compressed as heck. Also have to finish off 20 rounds of fire-forming for my 6 x 45mm and then testing will begin on that. Good luck and stay safe. |

No, I haven't bent the feed lips. As you wrote, some of the rounds do seem to rattle around a bit, but have not had any feeding problems. Didn't want to mess with success. You can get those 85's moving along at a pretty good clip.

Those of you using the 6.8 pri mags, what follower did you use to replace the spc one?
