The data I got from Hornady showed that the MAX load 10.1 Gr of Lil Gun powder behind the 20 Gr V Max bullet in Hornady cases with Winchester primer had a MV of 3,750 ft/sec from a 24 inch barrel. The 25 Gr HP bullet MV was 3,350 ft/sec with a MAX load of 9.2 Gr of Lil Gun powder. Have been looking around for different rifle brands , Ruger, CZ, and Anschultz may also be comming out with a 17 Hornady Hornet. I enjoy shooting 17 caliber rifles so I ll add the 17 H rifle to my 17 HM2, 17 HMR, 17 Fireball, and 17 Rem rifle group, when one comes out that I like. Hornadys web site lists cases , FL reloading dies, and loaded 20 Gr V-Max ammo . I entered the 20 Gr B.C. 0.185 bullet into my ballistics program with a 1.5 PBR and 3,750 ft/sec MV at 3,850 Ft elevation, scope center 1.5 in and got: at 50 Yds -0.05 in, 100 Yds +0.68 in, 150 Yds + 0.59, 200 Yds - 0.45 in, 250 Yds - 2.62 in, 275 Yds -4.17 in, and 300 Yds - 6.05 in. I live in prairie dog country and dont go out on windy days so the little 17 H will work out fine for me.
