I got the Hornady e-book for $23US off Amazon for Kindle.
NO, I don't have a kindle (except to put on the fire) but the app is free and I get the same info on laptop, phone etc..
Already had the book from last summer but that was the 9th, printed in 2012.
The ebook is the latest with 6.5CM anyway plus the Grendel and whatever else I don't know of....
A bugger to read (ebook) but a cheap way of getting the latest.
Also just bought into Lee but finding it irksome regarding xtra bits; poor supply chain and support so gotta wait for items to arrive from over seas.
I'd say it is fine to use but the RCBS etc does feel more robust!
