    The first time I ever shot 1k I made a second round hit on a milk jug. Is that because I was shooting a creed? I'd say it must be:D

    I adjusted the Start Pressure to align with the speed change I had seen when using Mag Primers, remember This is only an estimate watch Velocity closely and use the velocity to correspond to the pressure that goes with it. Start low work up along with velocity watch for other signs of pressure, primers, bolt lift, marks on case head etc. remember if signs of pressure show it is because it is above the limits for that cartridge, do not go higher and back down loads.

    I will give you 2 listings 1st with 2.800" COAL and 2nd one with 2.840" COAL (most mag lengths will handle this)

    Cartridge : 6.5 Creedmoor Hornady
    Bullet : .264, 143, Hornady ELD-X 2635
    Useable Case Capaci: 46.270 grain H2O = 3.004 cm³
    Cartridge O.A.L. L6: 2.800 inch = 71.12 mm
    Barrel Length : 24.0 inch = 609.6 mm
    Powder : Alliant Reloder-26

    Predicted data by increasing and decreasing the given charge,
    incremented in steps of 0.421% of nominal charge.

    Does the use of RL26 in the 6.5 Creedmoor necessitate using large rifle magnum primers or standard primers ?
    I see that Peterson Brass Co. produces 6.5 Creedmoor brass in both large primer pocket and small primer pocket configuration . Their website recommends the use of the small primer pocket brass if you expect to run pressure in excess of SAAMI specifications , as the brass will be stronger at the base and web . Will a small rifle primer have sufficient power to reliably ignite and fully burn a full case of RL26 propelling an ELD-M 147 gr. bullet from a 28" barrel ?
    All comments are welcome .
    Thank you ,

    I'm running lg primer with rl 26 in my own rifle. We have 3 shop rifles we are running 142's with 4451 & 4350 with sm primers. I'm going to try 4955 in the 3rd gun this wknd. That will be large primer due to being a slower powder. These are 700's were are demonstrating stock, accurized and blueprinted action with a krieger barrel still deciding if a mpa or MDT(my choice)chassis. The chassis is balance of cost vs performance. Since mdt is the choice for the factory I'm hoping that is the choice the boss makes.
