I have a chance to pick up a very nice Mauser at a giveaway price. The barrel is stamped cal 65x57 Gesch.10Gr, the former owner said it belonged to his grandfather and that it was a 6.5x 257 roberts and included 50 cases the have been necked up to 6.5. From my research it appears both cases are the same other than neck size and headstamps. I have no 6.5x57 to compare at this time but there does seem to be some factory ammo available. If any of you can enlighten me I would appreciate any info.This caliber looks like it would be a great candidate for lead boolits. Dies are affordable in the 6.5 57 and with all the new 6.5 calibers coming out the choice of projectiles with good ballistic coefficient is better than in the past. Thanks in advance for any input.
If I pick it up there will be pics
