winstonLT 1 Posted February 27, 2011 Report Share Posted February 27, 2011 Hey fellas, I just purchased a few cans of 7n6 from sportsmansguide. I think they were manufactured in 1976, making them 35 years old already. How much longer you think they will be reliable if unopened? Can I get another 30 years? Another 50years????

Mullet Man 2,114 Posted February 27, 2011 Report Share Posted February 27, 2011 (edited) Only one way to find out for sure. I'd think since they are air tight, that if there was no corrosion on the can or punctures, it should last indefinitely. EDIT; Stupid tiny netbook keyboard.

kresk 10,063 Posted February 27, 2011 Report Share Posted February 27, 2011 There are sixty year old sealed cans of one caliber or another for sale and I haven't seen any big outpouring of complaints about them for the most part. Quote Link to post Share on other sites
beefcakeb99 572 Posted February 27, 2011 Report Share Posted February 27, 2011 Well I shoot ammo from the great war...so I would say a long fucking time... Quote Link to post Share on other sites
brandywine 5 Posted February 27, 2011 Report Share Posted February 27, 2011 Well, I've fired hundreds of Bulgarian 7.62x54R rounds made in the early 50's over the last decade with no problems. They were in a spam can, but were NOT laquered or sealed like the 5.45 rounds are. I'd be willing to bet the 5.45 surplus will be good for AT LEAST another 50 years and probably longer.

patriot 7,197 Posted February 27, 2011 Report Share Posted February 27, 2011 (edited) I've had ammo from the late 1800s given to me that fired just fine. As long as it's stored properly it'll last longer than you will. I wish I'd have sold it to a collector now. It was original balloon head 45-70 ammo. I've also fired original WWI and WWII ammo, from various nations, most of it worked just fine. Edited February 27, 2011 by patriot 1 Quote Link to post Share on other sites
winstonLT 1 Posted March 8, 2011 Author Report Share Posted March 8, 2011 Alrighty, update to my update... I recently took my old british enfield .303 to the range with some south african 1960's era production surplus ammo. The ammo is corroded enough that the brass cases on them are slightly green in color. ALL FIRED! So that is 51 year old ammo that went bang on all 30 rounds! Giddy up...

G O B 3,516 Posted May 28, 2011 Report Share Posted May 28, 2011 I've shot WW2 Enfield and Springfield ammo with no problems. Quote Link to post Share on other sites
