Default making brass from 30-06

Buffalo Arms - Product Detail - 7.65X53 Argentine Mauser Cases - $0.56 brass
.300-.329 Diameter Jacketed Bullets | Shop .300-.329 Diameter Jacketed Bullets at Buffalo Arms

They are indeed good rifles as long as reloads are kept in the proper pressure range. You can get brass and ammo for 7.65 Mauser from Norma, but i find it a whole lot cheaper to make the cases from 30-06 cases. Just anneal them, full length resize, and trim to length.
As to making brass from .30-'06, just be aware that the base size of the 7.65 is larger than that of the .30-'06 so cases made from the latter tend to swell when fired. This normally is of no concern, but just something to know and watch for any problems.

.311 diameter bullets are available in 150 and 180 grain weights. Load data is kind of scarce, but for those two weights it can be found.
By the way, i too have had good luck in obtaining parts for them from the Gun Parts Corp.
