So I just bought a 7 stw from a member of LRH and I'm working on getting a load ready for hunting season. He used h1000 with 168 Bergers but I was fortunate enough to find some 180 so that's what I'm using. Here's the problem, I started my loads pretty low and started working up with h1000 planning on it being my powder to use and didnt even consider trying anything else but retumbo. I only load one round at a time and move up in .5 increments. But for some reason the velocities are everywhere! For instance, I loaded up one at 77 gr and another at 77.5 the 77 gr load crony said it was flying at 3061 and the 77.5 was going 3039!!!! All my loads with h1000 are doing this no matter how low or high I go. But with retumbo, I loaded one at 75.8 which crony said 2987 76.5 was goin 2976 and 77.0 was going 3005?? So I loaded 10 at 76.5 and shot 3 through the crony and it went 3023 3033 and 3035?? Someone help please??
