In an archived post someone said his the head blew off of a .22rf case by BVAC. He cleared it out & kept shooting. Said "Vern", his cat, was impressed. See
3gn.ar15.com/archive/topic.html?b=1&f=5&t=1019449 The cat impresses me. Ammonia, and/or fumes from kitty litter, mouse pee, horse pee - will all cause brass to crack. Store your ammo near the kitty litter, or the horse barn, and some of the cases will rupture. I speak as a metallurgist & as a former cat owner who noticed some old .22 spitting a lot in my .22 Kit Gun (yeah, it is old). Like the shoemaker's kids, I stored my old .22 ammo in the basement. Same furnace room as the kitty litter. In the 1860's when the British were bringing Civilization to the Indian sub-continent with the aid of .577 Sniders they had a problem with the cartridges. They cracked, split where the brass was stretched by that big .577 hunk of lead. Only happened in the monsoon season, so they called it "season cracking" So . . . in the rainy season where do you store the ammuntion? In the Officers' Quarters? Nah. You store it in the horse barn. It was the natural ammoniacal product of them thar horses what cracked the brass. I have an old (circa 1930's) English metallurgy book on brass alloys. They advise "do not store your auto in the horse barn" At that time, autos had a lot of brass trim. Might not have been the problem with the BVAC .22's in that guy's Mosquito, but I do suspect Vern the Cat might have had a "hand" in it. Mice do the same thing to brass items stored in old sheds or warehouses. Costly little beggars, it turns out. &c, &c. |

This is very relevant for those .22 3 gun matches. Oh wait what there are no .22 3 gun matches? there are in Dallas, so come on down south |
