Has any body tried any of these bases? The Tru Level Picatinny Scope Mount for Savage short action. I ordered item # HC-9100 for a Savage short action target single shot. It did not fit. At the end of the front radius, there was a flat that would not let the base come down to the action. Any feedback will be appreciated. Also the bubble level is hard to see with old eyes. Thanks for looking. Gene
