Never throw out your old reloading books.
I've went so far as to purchase old manwells.
I do enjoy data for new cartridges which will take an entire decade for the other sources to publish loads for.
I mean, I could likely use 22-243 middlestead or 22 cheeta data for the 22 creedmoor. (Or 22-250 improved)
I have only the 1 .300 Savage now and it's the model 81
Don't load heavy for it although it's not the sort that's weak.
