The 270win is the best cartridge to hunt with ever.

The 270's are fun cartrages to play with.

A fellow on LRSH forum built a custom 270 rifle with a 28" barrel if I recall.

He's getting pretty good velocities with the 160 and some custom 175gr'ers.

I haven't headed much about since I did the 10% lesser 30/06 thing,,, just finished ranging from 600 too 1000 meters on Sunday as it was hard to see the target due to the forest fire smoke rolling over the mountains.

Hope it clears up so I finish the rest of the way too my 16 or 1700 meter mark.

Nothing like getting this done for the 2018 F Class shooting thing coming up.

I call it the 308 winchester improved as the case volume allows for more gun powder.

Glad I had 30 % more bullet weigth too buck the winds out there,,, I can see the 212's and 220gr bullets doing better at this long range target shooting.

Weight does not buck wind. Bc does.

All things being equal the heavier bullet will have a higher B.C.

A number of years ago I read an article by Dr. Geoff Kolbe, founder and owner of Border Barrels in Scotland titled “Comments on Long Range Ballistics”. Dr. Kolbe’s straightforward assertion in that article was that there is no such thing as a bullet which is too heavy for long-range (prone) shooting. This position runs counter to the widely-held belief that there is a “tipping point” at which the Muzzle Velocity (MV) reduction caused by the heavier bullet will cause it to drift more than a lighter bullet with a higher MV. Dr. Kolbe demonstrated in his article that, for a given cartridge (he used the .308), as long as each bullet is of similar form and is loaded to the same pressure, with a suitable powder, then the heavier (higher BC) bullet will always drift less, regardless of MV.

Had to be said so there I said it! 10% more awesome than a 30-06 too.

I have killed all the big game species in my home province of Manitoba with the 270 Winchester more then a couple times over...

But I have also done it with the 243, 25-06, 30-06 and the 7mm Mag.
 
Have been shooting a Sako, Steyr, T/C Encore, LSA 65 and a BRNO Zkk in 270W (and maybe others I have forgotten). They all shoot well. Course so do 30/06, 308 etc etc.
Its never a bad idea to own a 270W ... although you dont have to hunt successfully .... as previously mentioned its a pretty good rifle calibre to have in southern Ontario

Most of the hunting articles I've read about using the 270 on moose end up mentioning the "follow up shots" required. One of the guys I work with used the 270 MSM on a moose. It also required a "follow up shot". I'll stick with 30's and over.

The same can be said for 30, 338 and even 375 at times. I've seen moose drop stone dead from 270 win. Not every animal needs a follow up shot, some need more, regardless to calibre size...
 
In every caliber discussion I have ever seen someone inevitable states that shot placement is far more important than energy on target or penetration/fragmentation.

Has anyone ever done or seen any scientific testing to evaluate whether a particular cartridge/load is more or less forgiving in terms of accuracy with regards to shot placement? Or with regards to probability of hit? Or with regards to getting an incapacitation ? I'm not talking about the anecdotal remembrances of very experienced hunters, but rather a deliberate, controlled, scientific study? You know, science?
 
The 270 is my best gopher rifle loaded with 90 gr bullet at 3500 fps, i just think it,s the best, would i use it for something bigger... Not sure i would... JP.

That is generally true as long as your looking at a certain or like style of bullet in one caliber. As you move up in caliber bullets have to get heavier to match the bc of the lighter skinnier bullet. A 270 and a 130 vs a 3006 and a 165 gr will be shockingly close in wind drift provided you use the same style bullet in both. The 270 in my experience is much more enjoyable to shoot than the 3006 with the above bullet weights and a stiff load. The deer will not know the difference.
 
A buddy of mine shot quite a few moose with his 270 without ever loosing or even having it go more than 100yds. I knew another guy shot quite a few as well with 25-06 no problems. I personally love my 30-06. Am I going to say it's the greatest caliber ever made? No because I haven't shot every caliber ever made. Only thing I can say is I have shot 270win and I personally wouldn't even think of giving up my 06 for one.

Yes, you can't compare RN to spritzer etc.

I have both .270 and .30-06 and am happy with both. They both get the job done for me. The .270 is great with 150 Partitions @ around 2950fps and the .30-06 with 200gr Partitions @ 2650fps. They just kill things quite well.

Brian Litz has done a fair bit of modelling where increases in mechanical accuracy, holding ability, decreases in wind-drift,
improvements in shooters wind doping ability and such are run through his modelling software to accurately predict an average difference in scores over a match. There's some science there. There's at least some on hit probably on game as well. No doubt someone has compared F open scores to FTR scores and .308 over .223 scores as well.

For the on game performance you just might have to go by the observations of very experienced hunters.
 
There is a Web site called "Thermal Ballistics Research" that covers every known caliber of bullet, cartrage out there.
From its beginning of time, factory loads of many bullets too the re-loads.

I always suggest people read the authors tutorial as it gives a person a brake down on the authors abilities at culling massive amounts of game around the world,,, 20.000 +++ if I recall.

I take some of his info at 50/50,,, but it is the closest too bullet and cartrage brake that I've found to date.
At least if offers ideas of what might work better in the long haul.

It was this brake down that put me back into the 30/06 category.

There are much better cartrages out there, and others with less wollp of impact.

One thing he mentions in his write-ups.

All bullets have their sweet spot,,, at so and so ft-per second this bullet delivers a Wack, it does the same at this velocity, but not as good.

The heavy weight bullets have one proven thing going for them,,, impact of penetration on thick skin critters.

Today's new bullets offer this in many calibers,,, but like the old saying goes,,, there's no replacement for displacement.

Old way of thinking I guess, but having a bit more of it than I need has worked for all these years,,, I'm not quite ready too find out other wize.
