I don't know about the ammo, but give us a report on the Ruger after you shoot it, mainly as to its accuracy. I have a used Ruger #1 in 7x57 Mauser coming. Should get it sometime next week. I have read that the number ones are hit and miss as far as accuracy is concerned. I have also read that some shimming of the fore arm or floating of the barrel or some bedding applied near the receiver may be necessary for good accuracy, i.e., to prevent "fliers."
