I have some books in my bookmarks that are maybe interesting for me.
Can somebody rate these books so I can see whats nice to have and which are not realy interesting?
No 1: Browning .50 caliber Machine Guns by Gordon L Rottman [color=#FF0000]( whats about .50BMG Cartridges in this book?)
THE GUNPOWDER INDUSTRY by G Crocker
No 3: Assault Rifle by Maxim Popenker [color=#FF0000]( good for russian Cartridges or only talks generaly and so its nothing for collectors ? )
No 4: Military Cartridge Headstamps Collectors by Guide Charles Conklin
