[QUOTE="JakeC, post: 2602033, member: 115819"] Yeah, I know you’re right I just worry that I’m missing a big hunk of the picture if I’m that far off. But I don’t think I am missing too much except some brakes on my imagination. I bought a magnetospeed and shot last Sunday and the original chronograph was way off as described by some guys above. My variations were identical across all 3 sessions, but in 85 degrees actual speeds are 2660 avg for the 180 and 3250 for the 140 AH. I was hitting high at 500 based on the calculators but that kind of truing is normal I bet. I’m fine with both of MVs, even though I’m a little sad I can’t get 3400 with the hammer. No real reason for that, it was just a goal. I could monkey with powder and get roomier brass but that’s pointless. I got to 3290 or so seating it long but I don’t plan on hunting it like that. I need to remember to correct my data on the absolute hammer thread when I get home from hunting. But anyway the animals aren’t going to care, I just got irrationally thrilled by the fake numbers I had at first. A scale is absolutely next on the shopping list, plus some other tweaks. My extreme spread over yen shots is 20 for the eld and 40 for the absolute hammer. I know I have consistency and tension to work on, and that’s a max not tuned load for the hammer but I know for a fact the scale walks around. Not a ton, but some. [/QUOTE]
