I just got a LIMITED number of Jane’s Ammunition Handbook’s 2011-2012.
These are the thick books, about the size of a telephone directory, but hardback. Everything ammunition related from .22 LR to 155, including mortars, grenades, etc. Info about the caliber, different loadings, manufacturers, history, M/V, bullet weights, etc. including photos and drawings. Reference section of manufacturer addresses. Hundreds of pages.
These retail for $1000+ (US) per copy and come out annually. When you see them for sale, they still run hundreds of dollars each and for editions that are years old.
I have a few for $175 (US) plus $15 postage (US addresses only), still in the originally wrapper. First come, first serve.
Email me for payment specifics if seriously interested. firstname.lastname@example.org
