Absolutely! There is only the .300 Win. Mag. which might do a little better with larger body animals and those with bigger teeth...
But the .30-06 is still highly respected by most knowledgeable hunters and shooters.
Buy it with confidence and go shoot it!
So what? And who cares?
The 300 WSM is fine outstanding cartridge fully capable of stopping any North American game. It has all the same range of bullets available that the .30-06 does but has more case capacity.
Notoriety has no bearing on cartridge choice. Some of us thrive on having little known or unknown cartridges because it sets us apart from everyone else! But it doesn't mean that we're sacrificing performance by any means. I've even shot a 300 WSM in competition in F-Class with stellar results!
Buy it, load for it, shoot it!
Enjoy the process!
