Default question.

You fellows are more experienced than I in the small case game. When I start getting pressure signs I back off to the next lower accuracy node. My question is how narrow is a typical node? I have noticed over the last couple of years that my .17's show very narrow accuracy nodes. Basically one tenth of a grain will show an accuracy node. Is this typical? I use an RCBS chargemaster to load all my cartridges. If you get variations in your charge of plus or minus half a grain this would throw you out of the node. Is the accuracy node this narrow because of the small case size? When you get even smaller cases than the Mach IV/Fireball do they get even touchier?? How do you deal with that? How can you safely work with a Velociraptor?
