Any of you have base-to-shoulder data on a couple (or more) rifles for the same cartridge? What kind of variation is normal?
Got a 7mm Mag coming, and want to load a few rounds for "w000h000, I got it" as well as break in.
I have a couple hundred once fired brass from an older Remington 700, and am hoping to get a handle on how far back to bump the shoulder, without being excessive, so the first 20-30 reloads will function properly.
I have a rule, that I shoot a new gun the day I get it, so I need to have a couple dozen rounds loaded before I get the rifle in hand. Obviously, once I have a few down the pipe, I'll measure its headspace, and size accordingly.
What's do you think the typical variation among rifles is? 0.002", 0.004", 0.010"?
