    Not sure what category the grendel belongs in, it's 6.5 but certainly not "big stuff" Anyway. I'm having a bolt gun built in this caliber 1-8 twist. I need some pet loads, trying to save time and money shooting a bunch of different components. It's fun but at nearly $30.00 a pound for powder, $40.00 for 100 bullets, $100 for 100 peices of brass. Thanks for any help.

    Buzzsaw-
    People have been having good results with 107 to 123 gr. bullets on top of Win 748, AA 2520, H335, Ramshot Tac & X-terminator, Varget, etc. I suggest you go to the reloading page on the 6.5 Grendal forum. Here is the link:
    http://www.65grendel.com/forum/forumdisplay.php?f=11

    My personal favorites with a 26" 1:8 ss barrel is Win 748, or AA2520 with 107 SMK, 120 SMK, and the new 123 A-max.

    But each barrel is different, so you will have to experiment to find that "sweet spot" of powder, bullets, seating depth, COAL, MV and pressure that your barrel will like to get the smallest groups.

    there are two different perspectives on loading this cartridge

    In an AR-15, there are platform imposed limitations due to weakness in the bolt that significantly limits the operating pressure of loads that can be used. Further, the AR15 places a COL limitation of 2.255 inches so you loose powder capacity with bullets shoved in the case.

    In a bolt gun, so much depends on what chamber you are using Alexander Arms 6.5 Grendel AR15 chamber, the 6.5 CSS chamber or the 6.5 PPCX chamber.

    The 6.5 PPCX chamber throws the AR15 book out because you are no longer bound to the 2.255 restriction. For example, in my 6.5 PPCX,,, the 108 Lapua is seated to a OAL of 2.365 inches and the base of the boat tail sits at the neck shoulder junction. Needless to say, that opens a lot of powder capacity that is lost shoving bullets back in the case in an AR. Also, the 6.5 PPCX is running only a .292 neck vs the .300" neck of the AA chamber or the .295 neck of the 6.5 CSS.

    I have used the 6.5 PPCX for many many years and still use it today all the way to 1000 yards in f-class. My two preferred long range loads use either the 108 Lapua Scenar or the Cauterucio 114 VLD on top of VV powders. I don't publish these loads because they are suited ONLY to quality bolt guns, not to the AR15, and I dont want people taking these loads and stuffing them in an AR.

    I will share my bolt gun loads with individuals who keep them for the personal use in bolt guns. There is a picture floating around here somewhere of a 1.18" group shot at 660 yards in my bolt gun using the Lapua 108.

    Feel free to email me if you want to discuss your bolt project.

    I had really good luck with VV 133 and Lapua 123 HPBT. I believe I used 27.2gr and 2.260 COAL. I found this to be equal to the AA ammo with the same bullet. In my 28" I was getting just over 2600fps.

    As aways, start with a lower charge and work your way up.
