Home Forums Hunting & Shooting Long Range Hunting The 6.8 WESTERN...

I too was in a store in Alabama and they had several boxes of Browning ammo on the shelf's but I did not notice what bullet weight.

My latest 270 Win barrel has a 1-9 twist and is 22” long. The throat length is increased to an OAL of a hair less than 3.5”.
It will move an old 170 Speer at 2730 AND I haven’t yet tried R26.

Someone wrote earlier that high BC bullets need more velocity. Apparently he hasn’t heard of the 6.5 CM.

I will keep using my ancient 270 Win until it starts failing.

Winchesters won't start hitting the shelves till May at the earliest,Brownings not till November...I just ordered 1:7.5 twist barrel,Ti action,stock,bottom metal,mag box and trigger along with a reamer and am going to have one made up with good quality components and roll with it

Agree. I have a 1-8 270 wsm and oal is something like .1 longer with berger 170 to lands than matrix vld and ablr and .2 longer than something like ballistic tip

I like what you’ve got going on! I just had a 1-7.5 Krieger dropped at the house. Waiting on a Deviant in a few more months and that’ll become my 27 Nosler. I’ve been really thinking of 1-7.5’ing my 270 WSM as well.

No Flys on the 270 WSM, it’s design was way ahead of its time, give Winchester the credit it justly deserves. I reload for mine and it’s performance is excellent,fast twist it and buy your own Custom reamer and your off to the races and you won’t be under powered . 270 WCF,270 WSM or 270 BEE , let them run !!!.

Don't really consider the .270 WCF "under-powered."

Even w/ the pokey ole 150 gr. Speer Grand Slam at a little over 2800 fps at the muzzle, it still carries 1250 ft-lbs at 400 yards.

...and the 140 gr. TSX at a little over 2900 fps, out to 500.


Would like to see a .277/170 gr. Nosler Partition.

What would @BobinNH have said?

Fortunately it looks like we’ll soon start seeing a bunch of improved .277 bullets I guess & suppose I’ll order an 8 twist someday

Hard tellin I guess but he ran enough twist on his 270 Wins to try those newer Bullets. He’d have a hard time giving up his 130 BBCs I’d bet though.

If only for conversation and because Facts matter,the 264 Kreedmire simply makes 1250ft lbs at 600yds,if only to your Drooling chagrin. Hint.



A .277/170 NPT would do farrrrrrrrrr worse,but it would recoil more and be louder in a 270Win,if such things horn you Fhuqktards up. Congratulations?!? Hint.

'Course an itty-bitty 21" 7-08 will "only" do same to the 800yd line. Hint.



You CLUELESS Fhuqking Droolers are a Hoot!

Fhuqking LAUGHING!...............

I need to run the numbers for a properly twisted .270 with some of the new high BC offerings. I’d like to build one just because the .270 seems to offend so many folks.😂😂

John

Those realities,are what makes the .277" soooooo very fhuqking HILARIOUS! Do it and spare no details. Hint.(grin)

Do NOT "forget" perspective either,like a .264" Hornie 147's .697BC and a Booger .277" 170's .662 version of same. Then extrapolate case capacity,to muzzle velocity and swing for the fhuqking fence. Hint.

LAUGHING!...............

Is there something inherently and mathematically "poor" about the .277" diameter that does not lend itself to high B/C bullets, or has there never been interest in making anything other than standard B/C bullets in that diameter?

That is to say: Has the .270 Win (or WSM or WBY or whatever) never been asked to perform at long range?

A long-throated, 1:8 twist .270 Win., pushin' a 150 gr. ABLR, would simply make 1250ft lbs at 750yds.

Mind your bib, sport.

Funny how it was considered a long range option for many decades. It was always considered a hunting round first, similar to the 25s I believe. Maybe it was the proliferation of range finders that drove it into less than what is considered long range these days.

I might add that of the long range options the 270 is the only one that was never a military caliber. Maybe that had something to do with it. 6.5, 7mm, 308, and even .338 have been military options.

The std. 1:10 twist - keeps the BC's in the hunting range.




GR

Creedmoorization which is like Californication but of the cartridge industry.

ANY caliber bullet CAN be designed for a desired BC, but some just haven’t yet. The SAAMI specified twist rate for the .270 Win and Wby are 1:10 so no really high BC bullets were designed for them simply because they won’t stabilize them. High BC .277 bullets are starting to show up now, thanks largely to new cartridges that have a fast enough twist rate to accommodate them, but they still haven’t caught up to the 6.5s, 7s or .308s yet. I predict we’ll be there before long.

John

At identical launch speeds the higher BC always wins, but you knew that. If you want to compare the 6.5 Creedmoor with the 147 to the .270 Win with the 170 EOL, the Creedmoor will pull ahead there too... But not until the 1540 yard line...
