Hello to Everyone, This is my first post to this forum. I've been reading and it looks like a friendly place to be a part of. I have a question to start off with. I inherited a Winchester model 37, 12 gauge shotgun and some very old ammo. The ammo is probably 30 to 40 years old. I'm wondering if there is a shelf life on the ammo and if there is a stability problem with it. I have a couple boxes of each of the following in 12 Gauge: Maxum brand by C-I-L Ammunition, Inc. Western Super X Winchester-Western Division of Olin Mathieson Chemical Corp. Remington "Power Piston" Plastic Trap Loads Remington Express Plastic Any help that someone could provide would be greatly appreciated. Thanks in advance. OhioPatriot.
