All of our Leathers are Vegatable or Oak Tanned, even the oil we use is acid free! we do not use nor do we recomend you use neatsfoot oil as it is acidic to some extent. However, you should not store your ammo in any Gunrig due to the natural formation of "Verdegris" (green stuff) that will eventually form no matter how the leather was tanned. I musta got befuddled about the shotgun belt Pard! :? , Ya want it fer a 20Ga ?
also, how's about the Gunbelt? do I need ta make ya one a wee bit larger?
