    Loading data from Berger Bullets

    Nukes asked me to post some new 130 grain 26403 Berger bullets loading data he received from Bob Blaine of Berger bullets. Here is a copy of his E-mail with him.

    Thank you for your patience while we had been working up our updated Berger Load Data for you and some other 6.5 Grendel shooters.

    6.5 Grendel
    130 Grain, PN: 26403 Bullet, 2.266" COAL, 24" Barrel. 6/25/2015 RB

    Please do not hesitate to get back with any of us with the Berger Tech. Team if we can be of further assistance for you.

    Rl-17, that's interesting. I'll have to try that out.

      Interesting what that chart shows, wish they had done this with the 130gr hybrid but Berger told me to use the data for the 130gr Target VLD for that bullet when I called and ask about Grendel loads for it.

      For the heck of it I ran the numbers for those powders through Quickloads and Velocities from it matched almost exactly (less than 10fps difference) to the chart for all powders if a 22 inch barrel was chosen. That program standard calculations does not take gas systems into account. Interesting that Quickloads shows all those to be under the 52k PSI SAAMI pressure specs that I have been told here are way off and low from some members testing. But then again I do not have pressure testing equipment myself to use.

      Reloader 17 really seems slow for the Grendel when Hodgdon says IMR4166, Varget and CFE223 are too slow. But when using heavier bullets often the slower powders work better a lot of the time in other cartridges I have loaded over the years.


      The CFE223 matches pretty close to what I have seen using the Berger 130 gr Hybrid bullets in a 22 inch barrel bolt action.

        You can get a bit more powder into the case if you vibratory settle, provided you are not exceeding max pressures. CFE behaves very well compressed so far from what I'm seeing.

          Working with CFE with 123gr, 129gr, & 140gr bullets, I'd suspect that we'd be able to get into the compressed powder range, safely.

            A Couple boxes of these bad boys just showed up.

            I randomly grabbed 5 pills from the first box and this is my empirical data.

            Bullet
            OAL 0.6585" =AVERAGE(0.6585,0.6595,0.6585,0.6565,0.6595)
            Length 1.294" =AVERAGE(1.2935,1.296,1.2965,1.297,1.2855)

            Hornady OAL Gauge/Forster Caliper Adaptor
            Bartlein Barrel SAAMI Spec Chambered by PF
            MAX OAL 1.747" =AVERAGE(1.745,1.7455,1.751,1.749,1.743)
            MAX COL 2.381" =AVERAGE(2.382,2.3855,2.3845,2.373)

            I intend to load up the following ladder to do initial testing (when I find time)
            Lapua Brass
            1.631" OAL
            2.265" COL
            CCI450 Primer
            CFE 223 Powder
            28.5 gr
            28.8 gr
            29.1 gr
            29.4 gr
            29.7 gr
            30.0 gr
            30.3 gr
            30.6 gr
            30.9 gr
            31.2 gr
            31.5 gr

            I based this ladder off the following
            My 31.7gr CFE loads for 123gr bullets
            I've narrowed down a 140gr CFE Load somewhere near 30.4gr
            LRRPF52's preliminary data on the 129gr ABLR, as well as mine.

              Silly question but isn't the OAL usually the longer measurement compared to the COL?

                the OAL is in reference to a measurement to bottom of the case to the OGIVE.

                CAOL is a reference to a measurement of the entire length of the cartridge.

                  I always thought OAL was over all length. Old school.

                    This is how I understand it and use the vernacular. I use OAL when measuring from the ogive of the bullet.

                      I thought OAL was Over All Length, same as COL (Cartridge Overall Length) I've been using BTO (Base To Ogive) for that measurement. I guess the abbreviation doesn't matter as long as you know what is intended.

                      So far it looks like I have good groups in the mid to high 29s with CFE223. Right now, it looks like 29.7 might be my best load, but I need to do some more testing. My best group overall was with a load of 25/9 of 8208XBR, 5 shots within 3/4 inch at 200 yards, but the velocity was only 2273. This is out of a 22 inch barrel, COL of 2.266, BTO of 1.659.

                        31.5 gr / 2388 Compressed

                        All cases were settled with a vibratory tumbler prior to bullet seating.

                        I based this ladder off the following
                        My 31.7gr CFE loads for 123gr bullets
                        I've narrowed down a 140gr CFE Load somewhere near 30.4gr
                        LRRPF52's preliminary data on the 129gr ABLR, as well as mine.

                        Accuracy was horrendous. I suspect both this bullet and my barrel are sensitive to the JTL. I think I'll take one of my lower charges and run a ladder test with different COLs to see if I can find some accuracy.

                        This was the ladder that I ran at 300 yards. The top target is the Berger target and the bottom target is a Nosler ABLR Ladder I ran directly after shooting the Berger Ladder.


                        The 11 pieces of brass in the inverted L shape to the left are the berger AA brass.

                        (The blown primer is from the ABLR 31.3gr CFE).
