OK. Here goes.
Back in the day, people sighted in like @mickey duck said. But this was the dark ages when @Tahr was out in a landrover somewhere and a calculator was something that you found at NASA.
Everyone talked utter shit because a range finder had not been invented. Most of the 350m shots were 150m and the 350m misses were 650m.
No one had a frame of reference so 270 was king because it was really fuck*n loud.
25-06 was better because while still very loud, it kicked less. A 117g sst will kill a deer real dead. A 110gr accubond won't kill a Tahr if you miss. Mix a 90gr power point varmint round in by accident and you will blow a hole in a small snow covered pigs shoulder that will not slow it down. All of the above is from personal experience.
The flat shooting thing was always bolox. Once Nasa shared the calculator around, we realised it never mattered.
A projectile cuts a 10" wound channel through a 10" kill zone, so to mess that up you need to be a lousy shot.
The proper way to sight in in 1970 was to put targets at 25m intervals all the way to 350m and measure the fall of shot on your reticle at a fixed power. But as nobody had a clue how far anything was this was pointless anyway. You might as well stick with the 3" high and low nonsense.
Today we know that a 25-06 is so overbore that by the time it's properly sighted in, the barrel is shot out. My own 25-06 is now a .280 because you could see the first 30cm of barrel was completely fuck*ng melted, with heat cracks visible to the naked eye. The kind of barrel a gunsmith cuts in half for people to laugh at.
Seems relatively pointless to melt barrels when if sighted in properly, something else will make the same 10" wound channel, with less noise, and the same mild recoil.
Bullets range from American penetration obsessed monoliths to target bullets which are basically a small copper bag full of lead. Depending on what part of the animal you hit and at what speed, either will be superb or utterly useless. If you have a good or bad result, make sure to market it extensively on the internet.
Some bullets slow down and fly off course less than others. It's hard to argue these are not better. 25cal does not have these. Thus your barrel was scorched for very little gain.
I would still own a 25-06
If all else fails, total and utter bullshit is as effective now as it was in 1970
I'm sure I ragged on 270 early in this thread. Recently I found out it was now universally uncool so I bought one. I like it a lot.
350m is not a long way if you have a range finder and plenty of practice (if your barrel lasts).
As of today I have no fancy LR rig and a weird collection of ordinary rifles in ordinary callibres with ordinary scopes shooting ordinary ammo. All carefully zeroed all the way to 350m.
These are all fun to hunt with.
I think I need a 25-06
