Why the .270 is obsolete

If the 7mm-08 was around 45 years ago I might like it better than the .270, but it wasn’t and I don’t. Even after taking an online sensitivity training class I still can’t tell much of a difference in recoil between a .308, 30-06, 280 Remington, .270 and 7mm-08. All of the above will work equally well for the hunting myself, friends and family do, so take your pick.

Really?

It was around 125 years ago... called the 7x57mm Mauser.

:D

I’m finding myself skeptical that a 270 can drive a 160 grain bullet at 2900fps and stay within SAAMI specs, and I’m someone who owns more than one 270 rifle. The first centerfire rifle I ever bought was a 270 so I’m a fan, but if I wanted to fling heavy bullets I would have bought something else.

RL-26. 150s at 3000.
 
Same here. That's nearly 7mm Mag velocity.

I’ve worked up loads for 3 of them and I’ve never gotten more than 2825 or so without getting flattened primers, but admittedly I’ve only tried 3 different powders. I’m sure there are faster ones than I’ve used. I don’t really chase top velocities anymore. There is always a bigger cartridge if you want chest thumping numbers.
 
Doubt even the rubes are amused by your parlor tricks.

- .277/150 gr (SD 0.279/BC 0.465)
- 7mm/160 gr. (SD 0.283/BC 0.475)
- 6.5mm/140 gr. (SD 0.287/BC 0.490)
are the directly comparative bullets.

Out of a 24" Bbl. and non-compressed loads:
The .270 Win. pushes the 150 gr. to 2900 fps. (ME 2800 lb-ft)
The 7mm-08 pushes the 160 gr. to 2630 fps. (ME 2460 lb-ft)
The 6.5 CM pushes the 140 gr. to 2730 fps. (ME 2320 lb-ft)

With commensurate recoil.

By any metric, using an 8 lb. rifle as e.g. for recoil, the the 7mm-08 (16.4 lb.ft) is inferior even to the .260 Creedmagic (14.4 lb-ft) for its minuscule 6% energy advantage.


No free lunch in Physics.

If you are happy w/ less?

...All the better.

You need a new source for load data. This is no fun if your just going to lie.

If the 270 is believed obsolete, then those that believe so are entitled to that opinion. My opined definition of obsolete is when component, cartridge, and rifle manufacturers stop making products in that caliber. Not when another cartridge is developed with a slight or even extreme advantage. So, long live all my “obsolete” rifle calibers.
 
"7-08 vs 270" is very much like "308 vs 30-06". The bores are 0.270" vs 0.277", very close. Most of the same stuff you hear in "308 vs 30-06" applies to "7-08 vs 270", but with some changes.

-7-08 has a lot better selection for long range or very heavy bullets
-270 wins in availability of factory ammo
 
We have all these little brass bottles of very slightly different shapes, all shooting little chunks of lead and copper at speeds somewhat faster than game animals can run or duck.
None of these are really obsolete, until the laser or plasma rifle comes along, or until a SUPER fast whitetail deer shows up.
 
I keep reading the same straw man arguments and “happy with less” bit. At what point then are we happy with size? 30-06 gives us more energy than .270 and .300 mags more than -06s. Are we at the point that those who have witnessed ethical kills in the field using 6.5s or -08s or... .243 are claiming more energy and recoil were necessary? Is dead really not good enough?

I didn’t have any snarky uncles, mine did own 30-30s and .308s and we all got along splendidly. We were not bound by blood to be polite, we simply chose not to be petulant pricks to one another. We also did not measure manliness by caliber.

You want an answer to the why of choosing something other than .270? Because enough gun is enough gun in the right hands on the right game. Would I invest in .270 at this stage of life? Nope. For any given shooter it may be obsolete or it may be ideal. That some people cannot accept for hunting there is a rather large overlap in effectiveness astounds me.

I don’t fault you.

I would agree, although I think it's .277 vs. .284 - so close it wouldn't be worth discussing except that there is a much better selection of .284 bullets - something I appreciate as a hand loader who prefers heavy for caliber bullets for hunting.

Also, when comparing load data, I sure wish people wouldn't cherry pick. Pulling conservative (Hodgdon) load data for the 7mm-08 and comparing it to liberal (Alliant) load data for the .270, or worse - specialized custom ammo - is apples to oranges and I suspect everyone knows that.

The "if your happy with less" statement is not mine and as long as it's "plenty" what does it matter. I use less pretty often so that's not a statement I necessarily agree with.

The "loud mouth uncle" is a tongue in cheek statement that happens to be true alot no matter who played the part of the uncle wether it be a neighbor, co-worker, etc. If it didn't happen to you, good, it's just more or less a joke. For what it's worth, it never happened with me and my family either.

With the understanding of there being a large overlap with most "standard" hunting rifle chamberings, like you stated, I guess you might would understand why on a thread where a poster is trying to tell everyone how the rifle they use (270 Win) and have used every hunting season for decades is no good and obsolete is going to have some arguments as to why they prefer a 270 Win right?

Actually it's odd with how you came into this with there's always a more powerful round and there's a big overlap in hunting chamberings why can't we let folks use whatever hunting round they want to if it's effective kind of attitude but then commenced to going against only things said by the 270 Win folks. This entire thread is someone telling people their rifle round is obsolete, no good, etc. Not the other way around.

Look at the title

Who are you talking about?
