My first 6.5x06 was built by Hart on a commercial Mauser action, Hart barrel, cherry wood stock with basket weave checkering, wish I had a picture but that was about two HD crashes ago. Seems like it had a C ring with the Mauser banner and no left side recess cut. Won several 100 yard running deer matches with it.

Have no idea why anyone would think a 98 Mauser was not strong enough for a 6.5x06, like saying it is not strong enough for a 270 Win, only a .013 difference in bullet diameter in an otherwise virtually identical cartridges. I use 270 brass to make my 6.5x06 brass, just trim, I do not own a 270.
