I would have to say the two bullets I used the most in the .270 are the Sierra Gameking and the Nosler Accubond. But the list of bullets used is long, TBBC, Barnes X, TSX, Partitions, Interlocks, SST, Speer HP, Core Lokt, Power Points, BT. I am set on a 130 premium for all hunting, and the GMX is up this year. If I had a dedicated Deer and Antelope rifle, the 130gr SST at 3150 would probably be it.
The 270 Winchester and old myths.
- Thread starter Why not?
- Start date
No, I haven't had the opportunity. In fact, I have found it near impossible to find the component for reloading, so I did the unthinkable and bought factory ammo
I will update, and this year will run the gammit. I have an antelope draw, and a bull moose draw with some deer in between. They are all going to get GMX's so we will have a good idea of capability when I am done.
It's not so bad. I was looking at the Hornady Superformance at Cabela's today and it supposedly pushes a 130gr pill at 3200fps in 270.
They say it's some special blend of powder which increases velocity without increasing pressure. Supposedly only loses 16fps for each inch cut off the barrel below 24".

anybody chrony that ?
Ive heard of people having a difficult time with bolt lift after shooting Hornady's "super" ammo . I dont' I have any available to try around here....plus my 270 has never been fed with a single round of factory ammo..so Im not sure it would forgive me
I dont' use "super" bullets either...Nosler Ballistic tips havent' disapointed. I also find them a little more consistent then others Ive tried .

Just returned from my second trip to South Africa. I've now used my Model 70 to take a total of 12 animals there, all with 150 grain Nosler Partitions. Ranging from Impala (about 40 kg.) to Eland (close to 1,000 kg.). Only the Eland took more than one shot (it took 3), and most were DRT.
What more can one ask or want from a rifle?

Yes. I have read a review where te author tested it in a firearm with a short 20" barrel. He found that it still exceeded the speed of any other factory load by about 200fps. If you'te really interested I can take a minute to dig it up.

I shot a Husqvarna Model 4100 in 270 for quite a few years. That is the little lightweight rifle with the 20 1/2" barrel. I used it mostly for sheep hunting, however it had no problem handling moose and bear either.
With 130 gr bullets and 62 gr of the old surplus 4831 in W-W cases it got very close to 3100 fps out of that short barrel, this verified on my Oehler Model 33.
I have no doubt that the new "Super performance" ammo could reach 3200 in a longer barrel.

Hi guys, i just have to say that in my understanding of physics, you simply cannot increase the velocity in a given barrel length, without boosting pressure.
The only way this would be possible is if the pressure was exerted over a longer period (without overpressuring).Usually accomplished by longer barrels.
If this DOES happen, then the realised velocity gain would far excceed the 200 fps claimed in a long (say 26" barrel).
Anyone have any proof of that?
I realise that some people are getting higher than normal velocity with the superformance ammo. But I suspect the pressures ARE higher.
Does anyone have a piezioelectric strain gauge (hope I spelled that correctly) to measure this?
That would be some qualitative information!
It would be awsome if this powder actually does what it claims.

Thanks for the heads up ID Currie.
The only thing that is still unanswered is:
If the velocity is 200+ fps faster with short barrels, then longer barrels would have much more velocity increase. (as mentioned in my previous post)
Has anyone tested this? The article says 16fps/" for barrels 24" and shorter.
If you shoot a 26" barrel, this could equate to approximately 96fps more than the 200 fps advantage of the superformance in the 20" barrel.(296fps increase?) that would be astronomical!
This I have to see!
This would change the performance level of the 3006 up to 300win mag territory.
7mm-08 nearly to 7mm Mag performance.
Sounds too good to be true.
It would be interesting to see if we have a true overall improvement in the worldwide firearm world!
The possibilities for all cartridge performance levels would truly be exciting!
The true powders that Hornady is using,(for factory loads) may eventually make it too market.
I understand that the superformance powder available to us handloaders is not quite the same as whats stuffed into factory fodder.
Anyone have info on that?
The concern I have is what kind of long term ramifications are there for barrel erosion? More/less?
Let me know what you gunnutz think.

Say what they may but I dont`think there is such thing as a free lunch when it comes to speed / Erosion /barrel wear. Mind you on a hunt rifle the gun may only last you two lifetimes instead of 3 or 4
This will affect someone in your lineage etc.Im just speaking for myself since I dont' put that many rounds in my big game hunting rifles......I end up shooting more with my Varmint / Smaller cals .
Pathfinder, you are exactly right on that.
Most guys never shoot a rifle enough to even come close to the accuracy life of the barrel. The first Husqvarna rifle I got in 270 Win, I owned for almost twenty years. It had fired over 4000 rounds when I traded it, and would still shoot five inch groups at 300 yds!
