Energy isn't everything though. All of those pumpkin rollers can put a big bullet out at moderate velocities and make an impressive hole. None of them are long range rifles because of their rainbow like trajectories and ballistically inefficent projectiles, but at close to moderate ranges, any of them are fully capable of dumping an elk. In some areas I hunt where it is crawling over lodgepoles and ranges rarely exceed 50 let alone 100 yards, I think I would rather have a Marlin lever action than my 7mm Rem Mag just because that is a lot of power in a more compact rifle.
