[QUOTE="Gamesniper19, post: 2899169, member: 95013"] A chrono is not necessary for a ladder test as long as the ladder is acting as it should. We are looking for a horizontal node at a specific load family. A chrono may not be necessary at all, even for running DOPE but that is a discussion for another day. I have run Retumbo, 7828 SSC and have some H1000 data. Retumbo ran the best although the real difference was not in group size, it was speed and recoil. I have a proof 9.25 twist in a 25 inch length. 210 ablr, cci 250, ADG brass - all ladders were run with .012 jump [LIST=1] [*]7828 SSC - 75.6 grains at 2872 - .41 MOA [*]H1000 - 79.2 grains at 2966 - .38 MOA [*]Retumbo - 82.1 grains at 3014 - .32 MOA I also had a decent node at 83.4 running 3057 but for the 43 fps i stayed at the lower charge [/LIST] Once I achieve sub 1/2 in a heavy magnum hunting rifle, I stop tuning. I shoot it to hunt not steel which I usually tune to sub .24 MOA or better in my 6.5 and 6mm stuff. [/QUOTE]
