My biggest eye-opener was my 30-30. I was getting almost 200 ft./s less than the advertised velocity. I immediately brought that to the attention of my Gunsmith. Then he said " those reloading manuals are optimistic."
He asked me if I was satisfied with the results (on Deer) with the 30-30. I said "Yes!"
Then he said "Deer are killed with bullets. Not what a realoading manual or a Chonograph says."
