    Kenndapp,
    PCC round is based on a 6.5 TCU, my 6.5 TCU contender would reach 2600 with the 95 grain bullets in a 14 inch barrel with little problem. and that was keeping the pressure limits at 48,000 CUP. the AR platform can handle 60,000-63,000 cups with ease. so the 6.5PCC should reach that speed with little problems.

    as a side note the 6.5 whisper was able to reach 2400 from 12 inch sub barrels during testing with 85 grain bullets and it gives up 30% case capacity to the 6.5PCC.

    hope this helps...

    Nick,
    have you tried the 85 grain sierra varmint bullets yet?
    the PCC hit .25 to .375 groups out to 300 yards this weekend with them. accuracy goes out the window after that but they are fun on water filled 16 oz bottles and gallon jugs...

    DR69er,
    hey I got myself in a argument about the benefits of the 6.5PCC over the blackout yesterday. what can you tell me about the subsonic testing you said was being done by the testing company you have working on the 6.5PCC? what weights are they using? have they tried the 160 grain bullets?

    Yup sure have and got about the same accuracy only at 100 yds! Don't have a range to stretch the shots out any yet. My load is 30.6 gr H335, CCI 450 SMRP, and OAL 2.285". This load nets 2861 fps from my 18" barrel. I will be revisiting this bullet using H322 and increasing the pressure a little bit to see what I can pump out of it.

    Hello all,

    Yes they did try them with the "heaviest loads" which normally
    means 160 grs. for the 6.5mm class...I olny recieved the very
    early/basic data from them...more details to follow as they
    continue testing...They were "very Impressed with the
    accuracy and reliability in subsonic form even with
    longer Bbl. lengths ".

    Puravida, If you can achieve that type of accuracy with the 6.5mm PCC round, you are blowing away 98% of the precision semi auto's
    in exsistance today using light weight high velocity lower BC pills !!!
