A recent search for information regarding .50-70 rifles and loading has revealed much less has been written about this caliber than its little brother, the .45-70. I have Mike Venturino's books, and have occasionally been able to access a few short articles online, but I quickly discovered that the late Croft Barker wrote several books featuring the .50-70. Unfortunately, none of Mr. Barker's books are currently being printed and used examples are demanding premiums as high as $300 per paperback copy. I was lucky to be able to order "The Yellow Book of Selected Articles" for a very reasonable $28.
I received the book yesterday, and last night when I opened the cover, I was in for a shock. By the way, I have the somewhat uncommon first name, Lance. It's like it was a from beyond the grave greeting.
