One of the 8-57's that I am shooting now has a carbine barrel length and showed low velocity and very low pressure with its inital work up. Since then I have increased the powder charge to over book max. and the result has been excellent accuracy and still moderate pressure signs except that it has not been over the chrono since.

Mine has the typical 'mauser' throat and the bullets are seated way way out to a COL of 3.25" due to the action being too long with a 3.4" box. My load is the 180 Ballistic Tip over IMR 4064.
