Re: 1891 Argentine Mauser
i hear ya. is yours in its original chambering? Most people that underwent sporterization had thiers rebarrelled to .308 or .30-06. The 7.65X53MM round they are chambered for is a very potent caliber and will fill the very close gap between .308 and .30-06 if handloaded carefully.
It takes 43 muscles to frown, 17 to smile, and 3 for proper trigger squeeze.
The latest caliber or gear is no substitute for experience and skill. Rifles and cartridges don't make hits -- shooters do.
Fact of life:
After Monday and Tuesday, even the calendar says WTF!
