 I just shot some 15+ year old .22lr with no issues.  I had "googled" old ammo and found many articles that noted you could encounter some misfire - failure to discharge.  They also noted it should be good for target practice, but because of possible misfire it shouldn't be trusted for self defense.
Hope this helps!
