"And your final statement above makes me want to get a confirmation from you: "All of which is why I advise loading to velocity, not the powder charge." RE: Nosler's top load with the 160 AB and 61.5 gr/RE-19 at 3046 fps. I am up to 63 gr/RE-19 and still only getting 2979 fps. I reckon you'd say keep going to that velocity? If I was getting the accuracy I wanted at 2979 I'd be happy, but would like to see what it does closer to the same pressure Nosler used, since their fastest load with RE-19 was the most accurate."
You statement assumes that a few more fps are always better--though that can vary some with RL-19 in different temperatures (which can also affect accuracy).I have yet to see any notieceable difference in "killing power" from a 160-grain 7mm bullet started 100 fps faster--or slower.
If you want to work up a load that's (at least theoretically) the same pressure as Nosler's data suggests,then fine, work up to 3046 fps (or whatever the equivalent is with your chronograph). But even for a rifle loony you're being pretty finicky.
