What's wrong with 270 WSM?

[TaperPin]

Nothing new?
133/135 berger
134 eld-m'
138 a tip
131 match king.....
Yes I understand they are still jacketed lead core bullets but the entire profile and in some cases, tip design are in fact new.
Compare the bc of that 120 grain to the 138 a tip and tell me there is no difference.

And again, this whole argument is tired and beat to death and I don't care what other people choose to shoot, but why make statements that lack any basis?

The ironic thing about 130gr bullets, is us old guys have grown up seeing fragile and tough 270 win 130 gr bullets hit everything that walks from every angle. Nothing new about that.

You’re arguing aerodynamics and that has nothing to do with what happens when it impacts the animal, only stretching out the distance of the impact. Two different topics altogether. I think aerodynamic bullets are awesome, but that doesn’t automatically make the designs better at killing things.

I find it entertaining that both topics get jumbled together - as if only aerodynamic bullets should be used at every distance.

Are you saying nose and bullet length and tip design has no effect on terminal performance then?
Longer heavier high bc bullets also have more length and mass than their predecessors. As I'm sure you already know. So wouldn't that equate to more terminal performance all thing equal?
I don't think you can say the only thing gained is aerodynamics in this case

130gr 6.5 tmk vs. .277 130gr interlock. Two totally different bullets. Do both kill? Yup. But the question is which one does it better. I’ve killed with both and my money falls on the 130 tmk.

If the bullet of a certain weight is quickly falling to pieces it doesn’t really matter what diameter it started out as. As it hits the hide, 130 gr 270 bullet and 130 gr 6mm traveling at the same speed are making 130 gr of shrapnel going the same speed. If it were a limited expansion bullet, the higher sectional density would penetrate more, but with fragmenting bullets it doesn’t have any impact on what the shrapnel does.

No matter what heavy for caliber bullet is looked at, just a caliber higher the same weight and construction will have a long history already developed. Hornady would like you to think the tip is very important and they speak about it in very colorful ways, even making tips out of different materials to seem extra cool, but it’s fluff. Aerodynamics yes, performance in the animal no. They purposely try to confuse the two by saying “The extra aerodynamics makes the bullet more lethal farther out.” Grammatically correct, but aerodynamics only gives you more distance.

If a bullet fragments off the nose as it penetrates tissue, wouldn’t the longer bullet be able to fragment more for a longer depth as it penetrates?for a mental picture, The idea of fragmenting bullets penetrating through tissue, to me, is similar to a pencil going through a sharpener.

Your original post mentioned the 120 grain 25 cal projectile and how there is nothing new or improved comparatively. My position is that isn't correct when you look at the newer 25 caliber offerings.

Now You are now comparing 130gr 6mm to a 130gr 270 which is a completely different argument.

But like I said this whole exercise in cartridge or bullet debate is tiresome to me. Shoot what you want, believe what you want, go out and hunt/kill what you want. I only engaged because to me you made a misleading statement about improvements in bullet design having no impact on terminal performance. Maybe I misunderstood you.

I would say a long fragmenting bullet creates a more desirable wound channel than a short fragmenting bullet.

In Victoria, Australia 270 is the minimum legal calibre for sambar which is what I hunt the most. I decided to give a 270WSM a try and ordered a new barrel at the end of last year, but went with a 1/7" twist so I could use some of the heavy for calibre bullets that have started to hit the market. So far I have only worked up a load with the Berger EOL 170gn bullet. I have not gotten out hunting much this year - so far carried it on one hunt but never actually shot anything with it as yet.

Fragmentation happens right away - looking at ballistics gel tests, the bullet is apart within the first few inches.

The Accubond clearly doesn’t do as much damage in the first foot, and simply spreads it out over a longer distance, which some of us like.

Use any weight bullets you want - most fragmenting bullets fall apart and do all their damage in the first foot, with little difference in depth of penetration between calibers.

There’s some great new bullets with improved aerodynamics, but once it hits fur, it’s just like any other bullet of similar design, same weight and same speed. The physics that are killing the animal aren’t new.

love it, its a great round

Interlock is considered a harder bullet - I’d bet lunch a 130 gr. 277” Sierra bullet isn’t noticeably different from the 6.5.
