Earlier today I found a couple dozen or so rifle casing in one of my storage lockers. I don't shoot or reload this type of ammo and I am not sure what the casings are for.
My guess is a military .30.06 case made by Lake City (Ammo Plant) in 1969.
I loaed a lot of LC 68 when I was shooting an M1 Garand in NRA
High Power Matches. Looks familiar.
