Eppie your loading area is entirely too neat
that being out of the way, if you are serious about long range get a single stage or use the LnL as a single stage and weigh each charge to the exact weight.
For hunting purposes + or - a couple of tenths is acceptable as long as you are not pushing the upper limits. For precision shooting each round should be an exact clone of every other round in the box. I can load 100 pistol rounds in 20 - 30 minutes easy on my LnL but 100 rifle rounds takes me about 4 to 5 hours because every parameter gets checked and double checked
here is a good article that every precision shooter should read
