[QUOTE="jcann, post: 903511, member: 37453"] I've shot Berger 180gr hunting VLD's using 65.8grs H1000 and have constantly achieved +/-2,950fps. The other day I decided to try my hand at shooting 180gr Hybrids using the same load of H1000. Base to ogive was the same for both loads, same die bushing, and same primers. The only difference being I annealed my brass prior to loading the Hybrids and had to use a different lot of H1000 (I had used up all the different lot of powder). When I ran the Hybrids through the chronograph I was getting 90fps less velocity; 2,860, 2,864, 2,867, 2,857fps. Could this velocity difference be due to the annealing, different length of bullet bearing surface, and different lot of powder or do you think the main culprit is the different powder lot? [/QUOTE]
