Knowing that bullet construction and performance is key to taking any animal, is there a minimum of foot pounds of energy for any particular projectile - to be accepted as an ethical and effective elk round?
I read authors fairly frequently that state it must be a 30 caliber or larger and must have a MV of XXXX feet per second - and then the next author states that 270 and 7mm offerings are acceptable elk cartridges.
I shoot a 22" barrelled 7mm-08 and right now, I use a Hornady 139 grain bullet that has a MV of 3000 fps (rated from a 26 or 28" barrel, I am sure) and retains over 1300 foot pounds of energy at 500 yards.
I can not shoot that far and have not even tried to practice at distances like this.
My question is - would this be an acceptable and ethical elk round?
If yes, is it yardage limited, in that it might only be advisable to shoot at - say - 300 yards?
I want to hunt in 2012 - so I have basically 22 months or less to prepare.
If I need to upgrade rifles, no problem..
Thanks - all help is genuinely appreciated!
