Weight seems to be a drawback to the Rigby, which requires a bigger action, etc.
The .416 Rem seems to be growing in popularity generally, the SS Ruger .416 in Alaska. Ruger built a package that seems to fit the needs of hunters in AK. Both are good rounds, either one I’d pick over the Rigby. My bud really likes his RSM Rigby, but it is heavy.
New powders and improved bullets make .416’s even more effective. So, the “good old days” of rifle technology is not as good as what we now enjoy.
