I've compiled an Excel spreadsheet of maximum loads for bullet weights of 95g. thru 130g.. I pulled these from Lyman 50, Nosler 8, Hornady 10, and Berger 1 manuals plus one tabulation in LoadData.com, and I included only the fastest-several loads from each manual's section. (I am NOT interested in in medium- or lower-velocity loads from any of these sources.) I listed each manual's barrel length and, so that I could compare more fairly these results, I then converted those velocities to those from a 20" barrel using Berger's statement that shorter barrels will lose about 17FPS per inch. I then sequenced the loads in descending order of 20"-barrel velocities. I also tabulated each occurrence of a particular power and summed those. From the 50 loads, the most-frequent powders were A2520 with 7 loads; BLC2 with 5; Benchmark and TAC with 4 each; and W748 and CFE223 with 3 each.
FWIW, I calculated the average of velocities listed by bullet. Using the 20"-barrel data, the 95g. bullets averaged 2769FPS; the 100s, 2738; the 120s, 2460; the 123s and 120-123s, 2493; the 123-125s, 2363; and the 129s and 129-130s, 2387FPS.
