It will save you a lot of time and ammo.
Good idea, in our current times bullets, powder and especially primers have been tough to come by

My depth changes are at 0.010 diff's...many bullets (I use OAL however so if you cbto you might to better) have 0.003-0.004 differences in length. sierra's can have up to 0.005 and these are all + or - type reads, so even at 0.005 for my tools, is tough to do. If you can do it, great. I'm not a match shooter so if I use 0.010 (as the nominal) I get results that I can see and use.
The nosler's I've used have been usually the tightest bullet lengths, more like 002-003.
I am using CBTO, I'm trying for 2-3 tighter groups in a row and then I'll use the middle of them, this allows for some variation and limits the impact to the group.
