You are right on the money. My reloads have shown an SD as low as 3 and as high as 8. I'm quite pleased with them, considering that most writers consider a SD of 10 good.
Geo_Erudite that is very good information to have, and I will follow up on it.
My thanks to all who have responded, something new is gained by all of us when we share or experience, knowledge and insight.
Kindest regards to all
