Has anyone used the federal lightning rounds in there Su or plr? Wallmart used to have them in the red box for $.96 but quit carrying it and went to the blue box classics. Well looking today and they had the lightnings back $1.47. That makes it cheaper than the bulk packs. The old ones worked well it my mountin eagle and 10/22. The top pic is the old box lower the new. They are 40 grain solid with muz vel 1240 FPS.
