Vic what was the barrels that were initially offered. I don't remember that they were "match" grade, just the standard poly stainless barrel offered by BH. Maybe it's that's the same thing

Does anyone have a 6.5PCC vs 300BO pic they can post?
Looking at the pics of the 6.5PCC next to the 5.56, it looks like there is some neck expansion done. Anybody got a case life idea? Expanding part of the neck from 5.56 to 6.5 should thin the brass in and area where 5.56 in my experience tends to fail a lot anyway. You guys using the 6.5PCC and reloading how many reloads have you gotten out of a single case so far? and what cases are you using mostly? LC, WWC? I"m going to take my time and digest the 6.5PCC. This would be a major move for me. Also a nice photo shoot of a 5.56, 6.5PCC, 6.5Grendel and a 300BO would be nice. Are the barrels stocked at this point or are you still special ordering? I noticed most of this website was around 2012? |

I noticed most of this website was around 2012? Case life is a minimum 4-6 loads w/o annealing...with annealing around 10 using virgin Lake City .223/5.56 brass. Case length for the PCC is about 42mm and for the .300 BLK it is 35mm. Cases are trimmed to 1.650" and then the case mouth/neck is expanded and case body is sized...Due to the case neck being shortened/trimmed there is virtually no change in case neck thickness. Preferred cases are: Federal/Lake City and Winchester/IMI, They offer the best case capacities and tend to be very uniform... The Info, prices, and load data are all up to date/current...start date not withstanding. Thanks. |

Just traded for one of these barrels and dies. Also got some amax and Barnes. Maybe in a few weeks I can post some results.

How does this round compare to 5.56 at short and long ranges and is there a way to make it fit into standard pmags?

The Hornady stuff is usually very accurate....the Barnes though can be more tricky due to the construction/bullet type combined with the polygonal bore (rifling), it typically does not do as well as conventional projectiles...this seems to be a result of the solid brass/copper material of the projectile not expanding enough to create a tight bore seal and thus less bore rifling engagement, also, brass/copper have a lighter specific weight vs.lead and thus require a longer projectile length for the same grain weight as lead core based projectiles...the plus side is copper and bore fouling is almost non existent with the polygonal bores and also have a slight advantage with added velocity. Anyway, enjoy your new rig and hopefully you will get plenty of enjoyment out of it...let us know how it woks out for you... Good luck. |

As a 6mm-7mm aficionado myself it is nice to have other weapons systems that have a common caliber...we got a LR .260 Remington for the longer range work, it is more of a bench rifle as it tips the scales at 13 lbs with a heavy target profile 24" Bbl., while heavy, it is very stable, with low recoil and is capable of 1,000 yard accurate shots with a quality scope...looking to have the barrel turned down and cut to 21" down the road... Thanks. |

Question: why do these seem to need modified mags but no on reports needing similarly modified mags with the 277 wolverine? It would appear that case should be more affected due to even larger bullet diameter in much the same way that the 762x40 is.
It doesn't matter as I have a big box of the 300 mags from a psa sale awhile back but just curious. |

It doesn't matter as I have a big box of the 300 mags from a psa sale awhile back but just curious. Because the shoulder on the Wolverine is bumped back so that the ogive of the 270 bullet rides the front mag rib. The 6.5PCC is a neck-up which means you have to avoid that pesky front mag rib in order to stack properly. The 6.5PCC allows for more case capacity this way. |

Wanted to give everyone a report, I had the cryo treatment by 300 blow inc, done to my 6.5 pcc barrel, I have not done enough shooting to say if it has made any improvement in accuracy, but I can say that I did see a 50 to 60 fps improvement in velocity on every load I have tested. I will send off my other 6.5 pcc barrel off as well as my 7mm -08 barrel next and see if I see similiar improvement on those barrels. |

Thanks Spinlite1, I had read and researched 300 Below Inc. and have found they have a very good rep In the Industry and they use the latest equipment and technology...I am glad it has worked out for you with your AR barrels, and am willing to bet that it will live up to the advantages that they say the end user will receive... I will be sending a few AR barrels to them as well to have them treated by 300 Below Inc. I believe the advantages they offer are worth the price... Good luck. |

Can someone post any available load data for the 95 Lehigh? I figure the Barnes 100 TTSX is not a bad place to start but would like any real-world data available.

If you go to page 40/41 on the thread spinlite1 has done some listed loads with the 95gr.CC. You can also email him he may have further load data with the 95gr CC. You also can use the 100gr Barnes pills as your start point... |

Using the 107gr. SMK's (length @ 1.225" w/ a .430 G1 B/C) loaded to 2.295" COL w/ fire-formed Lake City cases (32 gr. H2O capacity)
w/ a case trim length of 1.645" and a MAP of 59K/60K PSI, the numbers look like this from a 20" and longer barrel length: These are max. loads use with caution and reduce loads by at lest 10% to start: Accurate 1680 powder: 22.23 grs. @ 2,550 fps. @ 89% case fill @ 60K PSI. Alliant LT-32 powder: 24.70 grs. @ 2,552 fps. Hogdon H335 powder: 25.20 grs. @ 2,488 fps. Accurate 2200 powder: 23.57 grs.@ 2,562 fps. @100% case fill @ 59K PSI. Most powders in the above range will generally work, especially fine spherical ("ball") which generally work best... Hope this helps, good luck. |

Here is another end user load for the Lehigh 95gr. CC round:
26.8grs of H335 @ 2,615 fps (20" Bbl.) using non fire-formed brass. So with fire-formed brass (lake city or winchester) you should be able to reach 2,700 fps with some room to spare depending on barrel length, brass,powder, etc...with a 24" Bbl. 2,800 fps is possible... Thanks. |

While I am wearing out everyone on questions, has any consideration been given to benchmark, 1200r and/or power pro varmint? These all seem to fit the wheelhouse of this cartridge but I don't have quick load to even try. I have plenty of h335, but am always looking for a better mousetrap too.

Eta: the discontinuation of the 100 hornady sp and 100 Berger were much worse for this caliber - especially given the production 100 amax. Excellent points...those 100gr Bergers were top notch in every form... |

I use the 85 gr Sierra HP, #1700, out of mine with 30.6 gr of H355, CCI 450 SMP and an OAL of 2.285". The velocity has been recorded on average at 2969 fps out of an 18" barrel. Haven't had an opportunity to use it on furbearers yet,so don't know if it is friendly on fur or not.

At those velocities (3,000 fps) the 85gr TNT's will hyper expand or possibly "explode" on target and will
likely not achieve full penetration of the animal (e.g. Yote) depending on the size of the animal and the impact distance... |

Speer makes the TNT and Sierra makes the Varminter. I am using the Sierra Varminter, #1700 bullet. |

Speer makes the TNT and Sierra makes the Varminter. I am using the Sierra Varminter, #1700 bullet. Yep, I mixed them up...The TNT is a 90 grainer HP while the Varminter is a 85 grain HP...thanks for the correction... Interestingly, the Varminter has the best B/C at 1,600 fps and below w/ a .264 vs. .225 @ 2,700 fps and above... The 90 grain TNT has a B/C of .281 and a S/D of .184, no mention of velocity for the B/C number... |

Assuming the weather cooperates, I plan to finally get to test a number of loads up.
I have prepped (small) ladders of: 85gr Sierra Varminter 95gr Lehigh controlled chaos 100gr FMJ 100gr AMAX 120 Sierra Pro Hunter I also have 123 AMAX and 100 TTSX as well but don't want to just wear myself out shooting groups (I like to mix in some distance shooting with known loads as well as I have found it helps my stay concentrated when mixed in with smaller strings). Eta: all of these were loaded over h335. Posted Via AR15.Com Mobile |

Also, there seems to be limited data indicating that 1680 is a good powder for this in an 18" barrel (what I have). Very few weights are listed though in the spreadsheet. Is there a reason 1680 was moved away from. I saw heavy compression with the 85's in particular - it certainly seems a faster powder could potentially increase the velocity there assuming the pressure curve was agreeable.

AA-1680 is a fine powder that gives very good velocity and accuracy...One of the few reasons you
did not see that many loads with that powder is it is a relatively fast powder so it worked best with barrel lengths 18" and shorter (while many had 20" and longer barrels)...The other being that AA1680 was really difficult to find on store shelves for quite a while. So if you have access to AA1680 by all means use it for as many loads you can make use of... AA1680, AA2200, and AA2230 should all work fine with the 6.5mm PCC. Good luck and keep us posted... |

I do have 10lbs or so of 1680. Unfortunately, today's testing was cut short by a defective scope. I had a bushnell ers in the safe. I had pulled it off a rifle that I thought had an issue with a poor or damaged crown. Turns out, the problem was the scope. It wandered by more than 10 miles on consecutive shots. So, needless to say, the rifle went back in the case and the testing will have to wait until another day. |

Hopefully, your next session will lend itself to a much better outcome for all your hard work . Thanks for the update. |

Yep, they are usually .29/.30 cents per round...they have a .252 S/D and a .510 G1 B/C .They are around 1.200" long so they are not overly long for caliber considering the B/C and S/D numbers...They are usually quite accurate in most quality barrels. |

Twenty round C Products Defense 7.62x39 mags, with a 5.56 follower works pretty well. Mags hold 15 rounds, but that first round is a little hard to chamber. Ran fine other than that. COAL is around 2.3" .
Shot out to 700 yards today, on steel. Wanted to compare the 123 grain to 75 grain .223. The 123's were definitely louder when they hit. Rock chuckers.....
