Yes , the .270 wcf has improved noticeably with the amazing propellants and bullets these day... so have most all other chamberings . This has stepped up all hunting rounds into a new category, lessening the need for a larger magnum very often. The .270/ .280 etc has alot of capability on elk that it didn't have before.
Even Big bore , Ross Seyfried recommends the .270 wcf these days....Eileen does too( right JB?)
