Browning: Factory Fast-Twist .270 Winchester

[WisBorn]

I have used the 168 ABLRs from my 28Nosler and wasnt thrilled, i think they open later than the standard ABs and don't blow as large a holes.

Thanks for your opinion on the 168gr ABLRs. I was going to give them a try in my 7rm. I think I will give the 160 ABs a try instead. I have had really good results with the 180 ABs out of a 300wsm.

@Varminterror my question was manly the 7rm compared to 7 prc, Not the 270 win.

Ah, gotcha. The 7 RM struggled with mag length and action length. A lot of us did long throat chambers with single feed ammo in fast twist barrels in 7RM for a long time - same with 300WM - but the 7 PRC allows longer ogives ahead of the shorter case, moving the bullet base (or boattail junction) more forward of the neck/shoulder junction too, which meant the shoulder had to move backwards, and to keep case capacity, they had to make use of the full diameter instead of stepping down in front of a belt. Much shorter case with a more consistent powder column burn, nearly identical capacity, better bullet position relative to the pressure front. It’s all upside.

The 270win will always be a good deer round. And has benefited from the technology improvements. I just don't see that it gains much from the faster twist barrel.
Will the 7mm Rem Mag gain enough with the fast twist???

Shifting a 270 from 120-140grn bullets to 150-160 should mean extra range, but it’s not a major change. Maybe it regains a little ground to middle the gap between 6.5 swede and 7 RM again. My custom 7RM is a 1:9” twist, meant for shooting up to the 180 class bullets, but I could be happy with it in a 1:8 instead, and probably a lot happier with it as a 1:8 7PRC. Shooting the heavies out of the 7rm, when they fit (single feed) adds performance downrange.

No, adding a fast twist doesn’t typically improve performance to match the next level of cartridge/caliber class, but it does shift performance in that direction significantly. I’ve done “fast twist” barrels in 22, 6mm, 7mm, and 30 cal cartridges going back 20yrs, so I’m definitely a believer in the advantages.

Interesting.

4-500 yards - would probably require at least a new load, if not a new rig.

A "sneak," which I truly enjoy, to inside of 300, or still hunting in the pine thickets and oak bottoms well inside of 100, covers most of my current hunting.

Stand hunting - is not really my thing.


Feral cattle...!?!

That would bring the 9.3x62mm out of the freezer.

How is the eating on those things?

"Feral" can range from a generation or two out meat cow, to a stubby, heavy, and angry pickup truck with horns......former taste good, later....not so much.....

 

[mshootnit]

Should be just the thing for paper punching. To me, if you can't kill it with a 150 gr. partition, time to move up to a bigger case and bore.

If it simply moves that 150 gr. partition's effective range from 400 to 600 yards, with little or no increase in powder or recoil, why the bigger case and bore?

Feral cows - sound like an interesting addition to my understanding of the fauna there.

What is the best eating of your sheep/goat/pig fair?

What they eat can affect how they taste.

I always thought that 150's in a .270 were decent elk/moose rounds, and wouldn't feel under gunned. I've wondered if a 1:10 .270 would stabilize 160 Partitions, which would be even better. I figure that it would, but be marginal. A 1:7.5 or 8 would be the ticket.

If by "it", you mean the faster twist, I don't think it will add range to an already stable bullet. The limiting factors will be where it goes transonic and where the velocity drops below what is needed for reliable expansion, neither of which is twist related. It would allow a heavier, higher BC bullet to carry velocity further downrange.

But as said, if you feel undergunned with a .270 there are many options to move up to something bigger.

Was referring to the fact that the increased twist rate would facilitate the use of higher BC bullets, including the long 150 gr. ABLR, that would essentially increase the effective hunting range of the cartridge, with no increase in powder and little or no increase in recoil.

What they eat can affect how they taste.

Personally I prefer to eat pigs that were eating farmers plants.....they generally taste better and have more fat.

Sheep don't change that much in flavor by the area, but i prefer the ones that have more Mouflon than sheepy sheep. The flavors milder, and they arnt as oily.

Cows..... well if it looks like a cow it will probably be pretty tasty.
If it looks like a powerlifter well past their prime (and a few to many steroids) Ill give it away.....

I think that the range increase offered by the VLDs will be modest at best.
IMO the .270s a good 4-500yd hunting cartridge, and the VLDs make it a better 4-500yd cartridge, but were already talking the edge of what your average shooter can reliable achieve. Slightly decreasing drop and drift isnt going to make it significantly easier to hit with for someone who couldnt already hit reliably at 6-700yds.
At that point were really back to talking about energy/penetration/damage on target. There the retained velocity will make it more effective, but your start velocity is dropping appreciatably once you start getting a lot heavier than "standard" bullet weights.

Again tho 3000fps is my happy place, and in a .270 145-150s where id want my bullets to sit. ......150vlds in a 26" would probably be my jam....tho id still probably opt for the AI version. Id also opt for a gun thats in the 8-9lb range where as a bigger round id be looking 10-11lbs or so.

As stated, think with a longer COAL/throat, it would make a solid 2,000 fps/1,500 ft-lb/600 yard rig.

But can't really see when I'd ever use it in the field, where 250 or less is the norm.

And even with the economic advantages of existing reloading components and re-barreling a sidelined, long magazine rifle, there is still the added expense of a dialing scope, bipod, and laser equipment.

Starting from scratch, it would be a no-brainer, much like the .280 AI.

 

[Gun-Reck]

The 270 is the mini van of cartridges.

You could put a turbo on a mini van, make it go faster, try selling it as a sports car but at the end of the day it’s still just a basic, homely, grocery getter.

Shelby GLH-S

"The main differentiator of these cars from their regular Dodge versions was their use of what would become the intercooled Turbo II engine as well as Shelby Centurian wheels, Koni Adjustable shocks/struts, and changes to the alignment...

...It also was significantly faster In the quarter mile than the Chevrolet Camaro with the 305 V8, Pontiac's Firebird/Trans Am with the 305 V8 and pre-1987 302 V8 Mustangs, and equal or slightly faster than the 1987–1993 V8 Ford Mustangs and Corvettes."

I thought the exact same thing. I don't think the 270win can get enough velocity to make the heavy high BC bullets shine even with the fast twist barrel.
The 150 grain bullets are a good top end for the 270win

150gr 270 Winchester kicks like a Missouri mule in my Mossberg Patriot lol. Idk if I could handle a 165gr!!

How is the total weight of the Patriot?

I'm not sure, but even my custom Remington 700 fast twist 25-06 kicks like a Missouri mule as well... I need to check the weight again cause I'm not 100 percent sure. They both have walnut stocks. The Mossberg is a sporter barrel and the Remington is a light Palma barrel.
I have a patriot predator in 6.5 PRC and it's a light weight rifle with a polymer stock and sporter barrel. It's got a muzzle brake so it actually is pretty tame.

 

[Gun-Reck]

My sons have the synthetic-Vortex Scoped Mdl., chambered in .270 Winchester.

They are ~ 7.5 lbs., all up.

And while they also come with an nice recoil pad, we also shoot mostly 150 gr., and would not be in any hurry to exceed them.

Just curious, my MarkV 7rm is about 8#s field ready. The rifle design has a lot to do with the recoil. Yes weight tames recoil, but good pads, stocks, and design helps also.
I had a Axis 270 and I don't remember the recoil was to bad. I think the heaviest bullets I shot out of it were 150 Partitions.

My Mossberg Patriot walnut 270 is about 8lb according to our bathroom scale. That's with a sling, vortex viper HS 6x24-50 scope, loaded mag, and stock sock with 9rds in it.
My 25-06 weighs about 10lbs(!!!!!) and that's with a 20moa pic rail, scope, same model scope as the 270 actually, and it's a custom Remington 700 BDL walnut stock with aluminum bottom metal/internal mag with a Timmney trigger.
My 6.5 PRC weighs between 7-8lbs and it's a synthetic Strata camo stock with the same scope as the above two rifles and with a loaded mag. Idk how accurate this scale is but it jives with other people's answers on here so idk.

Yup. Nobody cared then and nobody (normally) does now. Watch Mecum auctions. I very much doubt that is was faster than a 93 Vette, If fact the Corvette is over a second faster in the 1/4 and top end is way faster. So your article is a lie and that car is not a mini-van. I used to race cars. You could also buy a Cosworth Vega or Supercharged Buick. Faster yet. Another of history's who cares.
I agree with varminterror, It is something for Old guys that bought the Winchester gun writers myths about faster and flatter that weren't true. I really don't get emotional attachment to a cartridge. There are plenty of options that are better if you want a more accurate or faster, or bigger payload bullet. The 270 is and always has been a good hunting cartridge at normal ranges for most people. If you want to pretend it's more than that it's a free country. Somebody is happy to take your money by pimping it up a bit. Many old favorites are dying out as the shiny, new, more advanced stuff gets popular and pimped by the information age. Since a faster twist rate is never going to make it a match round I would leave it alone as it's relative instability helps it as a hunting round in my opinion.

"Feral" can range from a generation or two out meat cow, to a stubby, heavy, and angry pickup truck with horns......former taste good, later....not so much.....

These are on my wishlist!

I shot a lot of .270 Winchester for a couple years. Killed a Black Bear and a deer or two. I shot the 135 SMKs out to 800 yards on steel. I never tried anything heavier, before moving on. Game was shot with 130 grain soft points. All at 125 yards on less.

Certainly sound emotionally attached to this one.

It simply gives the .270 Winchester cartridge the advantages that the .280 AI has, because of the increased twist rate.

That's it. Instant "bean-field" cartridge. Plenty accurate, fast enough, and plenty of bullet payload... and getting better.

Along with the Mossbergs, which are on the light side at ~ 7.5 lbs., have also shot piles of 150 gr. from M700's and M70's.

All have traditional straight stocks and recoil pads, like the Patriot, and all are all day long precision shoot-able.

And this coming from a guy who traded down from a perfectly nice M70 .30-06 and 180 gr. ammo, because it was not.

But that's just me.
