I’ve gotta say I was disappointed in this “revised edition” reloading manual which I purchased to update my 6th edition version purchased 22 years ago when I started reloading. It was a very informative read & I wanted the updated information of a new edition. I wanted reloading data for the 17 Hornet - not included. I wanted data for the now popular Hornady 160 gn 30/30 bullet - not included. I was surprised to see 8208 powder not listed for the 204 Ruger as I find it a very suitable powder. If this is your first NH Reloading book, you’ll probably be satisfied but if you just want to update an earlier edition with data on modern projectiles, powders & calibres you may like me be disappointed. I’ll probably continue to use my 6th edition & sell this one to someone that needs it more than me. Might get the Speer 15th edition reloading book instead, even though ADI powders aren’t referenced in it.
