Re: 7.65 ARG ???
Actually its not a bad round. My father was a fan of the 7.65 Argentine round and action.
The M-91 Argentine Mauser action is as strong as the 93-95 Mausers. They don't have the third locking lug, nor the provison vent the gas of the '98s, however the deep recessed bolt head and narrow extractor slot provide more cart. head support then the later mausers, including the 98.
The 7.65 round is on par with the 8 MM Mauser and the 7.62 Russian and can be quite accurate if proper handloads are used.
It's just one of the many surplus military actions that were popular in the 60s.
I had an as issued model and access to my father's sporter version but like a know it all kid, I wasnt into do old military rifles back then, I had to have the fancy stuff. Now that I'm older, and more into history of old military rounds, I reget I got ride of these old work horses.
I don't think I'd choose the action for a LR Rifle build, but I would love to have another "as issued" version to try out in CMP's Vintage Military Rifle Matches.
