I would wager if you have to go on this website and ask if the 30-06 is good enough for ELR hunting, you probably aren't ready. Not trying to be insulting, but most anybody that is experienced, driven or has an idea of L.R. or E.L.R. knows they can go online and look up the load data and ballistic tables of about any cartridge out there... and they can deduce from those numbers whether a cartridge is up to the task. Better yet, they will plug their numbers in to Stre Lok or some other ballistics program and get their answer. Will your bullet have the terminal performance required to make a clean kill... not a hit, but a kill? Will it have enough fps to perform correctly at your desired range? Will there be enough fpe left to cleanly kill? Those answers are found in ballistic tables/programs. Then, YOU have to determine which, if any of those bullets will be preferred by your rifle. "John Smith" or "Leroy Brown" cannot give you that answer. They can tell you what THEIR rifle can do, and at what distance... that is about it.
I had a thirty-eight hear old acquaintance come out to deer hunt behind my house last weekend. For the third time he stated to me: "You are going to have to show me how to shoot long range". He borrowed bullets from me to hunt with... THAT DAY! He asked where he should set up to hunt. I asked him how far he was comfortable shooting. He bragged that he could hold baseball sized groups at 100 yards!!! He did kill a stomper of a buck, at 150-200 yard. He hit it in the jaw, the neck and the gut. He is not even ready for moderate range hunting IMO. If he settles for those type of 100 yard groups and shows up without bullets, his mind and drive are not in the right place to be an accomplished shooter IMO. You have to want to put in the time and effort to research, to tune your equipment, and to practice. Honestly, OCD helps, lol.
Not saying you don't have that drive, but long range shooting or hunting doesn't come automatically without effort and dedication. I limit my shots to 750 yds and in on game, and it took money, time and dedication to become proficient and confident to this point. It is just a personal limit I set for myself.
There are better cartridges for E.L.R. hunting. No sense in arguing that. Personally, I would limit the '06 to 700-800 yds, maybe less, which does not define E.L.R. in my mind. I no longer hunt with an '06, but used to quite a bit... and may again some day just for nostalgic reasons. It's a fine cartridge with a proven track record.
