I would still use it for the 06 but I no longer own one, I have a .300 Winmag now. I miss the 06 though and may buy another one soon, since I used the 06 for most of my life(69 now). The 300 kicks a little too much for my tastes, but it sure drops a deer in it’s tracks:)
An M1, one of the Kimber Mauser's, a Brazilian military Mauser, and a low serial # Springfield that's never had a live round fired through it except when it was tested maybe.
My old man got the Springfield after WWII. They were handed out to veterans to be used for when they brought the bodies back for burial, so it only had blanks fired in it.
One of these days I might try a couple of rounds in it.
