The only reason not to use it regardless of any other rifles you have to choose from is peer pressure, lol.
For me, tagging different species with the same gun is a fun pursuit. .270 Win and 30-06 have each done pronghorn, whitetails, mule deer and elk in my hands or the hands of my sons. 35 Whelen AI hasn't done a pronghorn, but flat works on elk, muleys and whitetails. My 300 Win Mag in post #9 has done all but pronghorn. Kinda proud of that core of cartridges taking care of literally any needs in 30 years across multiple species.
