DLA-Interesting yes,but I certainly am not going to ask my 45-70 to do what my .300 Win Mag does with ease.Here's the clincher,If I new I would see Elk from say 150 yards to whatever,I would take my .300 Mag.I bought my 45-70 for the thick Timber,not to shoot 200+ yards.
Don't take me wrong,I love my Guide Gun,but for an all around Elk Gun the .300 Has my vote.But in the heavy timber the 45-70 without a scope is quicker.Like all the rest,I have fallen into 45-70 Fever.But you can't expect the 45-70 to do what other's do with ease.AKA long shot's,yes it will,but where do ya draw the line?I think un-scoped it is 100 yards + a hair or two.With a scope it's probably good to 250 + yards,but like I said if I was expecting shot's that far there are better choices of caliber's.If you believe in number's the .300 has at 400 yard's a velocity of 2200 fps and energy of 2145 with a 200 grain Nosler,I think the Elk would notice the difference.
Just my opinion.Jayco.
