I fired Federal Lightnings for years.

1. Beacause they were cheap.
2. Bacause they were accurate.

"The American Rifleman" ran a test several years ago, and Federal Lightnings came in 2nd behind Eley Tenex. They outshot EVERY other type that I tried. 30 years passes....and I read an article in a book "The Book of the 22". The author notes that most 22's will not shoot a different ammo well for quite a few shots, often a box or two. The difference was most apparent when changing from lead to copper or from copper to lead.

Dadgumit! I NEVER shot a whole box of the different ammo thru my gun before I gave up on it. I'd fire a 10 round pattern (instead of a group) and quit using the ammo. I used Lightnings forever untill Federal quit pushing them and went to the new big box HP's. That's what I use now.
