Nimrod, I agree H110 is great to work with, usually a tenth or less variation. I check every round also, but I do it with a light, not a scale. Some people just like everything exact & there is nothing wrong with that at all, peace of mind is worth something.
I'm assuming you are using the exact same brass, not mixed, the brass is all trimmed to the same length, primers are seated with a hand tool with a dial indicator attached, you are using a 4 die setup where you seat & crimp seperately & the bullets are weighed before seating to make sure they are the same weight. Last, you are using another dial indicator to check your finished loads for runout. Then, after all this you are shooting your perfect loads in an iron sighted revolver with 5-6 seperate chambers.
I really did start out the same way you describe but got lazy over the years & realized I couldn't shoot the difference but we all have certain habits that we don't want to change. I do know you will never have a squib load or one that is overly hot, etc. the way you are reloading & are probably an excellent shot, so don't change anything.
My main excuse is, I can't see the sights, so I can always fall back on that.
