My father handed down an amazing Marlin 336 (.30/.30) to me before he passed away on my 16th birthday. It is so much nicer (action/blue/walnut) than what I see today. I have a beautiful Winchester Model 70 feather weight (Stainless) in 300 Win Mag (Leopold 3x9 VX2 to match). I love the 336, but hunt Elk. Is the new Hornady (.30/.30) Lever Revolution ammo sufficient for knockdown power (Elk) up to 200 yards, or should I spring for the 45-70 with the same ammo? My 300 mag is really nice, but I am partial to the lever action. I am aware of the range and knockdown power of the 300 mag.
