I ran you a Quickload table. Without knowing details, I left desired pressure at the QL default, used a 21" barrel and set the seating depth at one bullet diameter. Given that the 6.5 Carcano is only rated at 41336 psi, be warned that an overpressure load may not show any visible signs of excess pressure. Unless I was confident the gun has lots of margin, I would be extremely cautious.
Also, please look at Hodgdon's on-line tool, it does have load data for jacketed 160s.
Code:
Cartridge : 6.5 x 52 Carcano
Bullet : .269, 160
Seating depth : .269 inch
Barrel Length : 21.0 inch = 533.4 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 36168 psi, or 249 MPa
or a maximum loading ratio or filling of 105 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
