I've found the 25-06 to be a nice medium, flat shooting round, and through the decades, I have used it on P-dogs to elk. Loaded with the 85gr NBT @3,600fps from one of my old 26 inch varmint tubes, I took my first 1,031 yd P-dog 3 decades ago, and it shot countless shorter range dogs under high winds. Using the old Barnes 85gr X-bullet loaded @ a "warm" 3,750fps from a 26 inch, it was a banjo wire on Southern whitetails across bean fields, pastures and clear cuts. Today, the 80gr TTSX fills that role.
For elk and larger Western mules, I load the 110gr NAB with Retumbo @ 3,310fps. It simply does the job and holds tight groups. Years ago, I even played with it on the 1,000yd comp line, but that was just for the fun of it.
