Does anyone know a way to reverse engineer a factory load? Obviously it's easy enough to copy the dimensions and choose a similar bullet but I guess it's the powder that's the tricky bit!
My .243 really likes 100gr Federal powershock...
but once my stock is run down I'm planning to move onto reloading for it. I have a similar issue with my .223 - it loves Sako 50gr 'Arrowhead'.
I was wondering if there is any information out there with regards to what powders are most similar to what factory loads to assist with choosing a suitable powder. Then it would just be a question of working up the loads from minimum in the usual way.
Or is trying to short-cut the normal process an exercise in futility?
