RE: POWDER MEASURE
I only use 5gr increment powder measures and for pistol I use a single grain measure.
Ishootmostly FFFG (3FG) powders (BM'3, 777 & Swiss BP) and I have found overall that a 5gr increment can make a significant difference in accuracy depending on the rifle and projectile.
That said, I can also often find decent hunting accuracy loads with a 10 grain increment measure. Certainly with FFG (2FG) powders.
Sure, I could set one of my 10 gr measures in-between a marked range, but I would rather have a specific 5gr increment.
