Home Forums Hunting & Shooting Ask The Gunwriters Short Action .277 ??

I will try this again in the furom I intended:

With the military looking for a .277 (6.8) round for their new rifle system I have been waiting/hoping to see a commercial short action .277. So far I have seen some information on the .277 Sig Furry. It looks to be a "hybrid" case and can't tell if the pressure of the case will allow it to be in a standard bolt action and not reloadable.

Are there others out there being developed?
Am I misreading the Sig Furry?
Will there be brass for it?

I know there are the 6.5 Creedmoor, the 7-08, etc., already so no need to suggest those

Does the 6.8 WESTERN ring a bell...?




GR

The "military" reference was meant to indicate short action, NON-MAG cases as there were supposedly several in the works (6.8 Western not being one)

6.8 REM SPC.-- I hope somebody would make a good bolt action chambered in this cartridge again. I do not hand load yet so I also wish for some decent/faster hunting factory ammo. I did put together an AR in this chambering last year and it worked well on 2 deer..... Joe

The .270 Redding has very similar dimensions to the .277 Sig Fury

270 WSM is a short action cartridge.

The traditional bullet weights of 130 & 150 grains are well served by the 10” twisted 270 Win, 270 WSM, and 270 Wby There are some new bullets appearing in this caliber, but they require a little tighter twist to stabilize. It remains to be seen if the 6.8 Western will actually thrive.

On the light end of things there are the bullets more suited to the 6.8 SPC size of cases.
Tough to match 270 Win / 130 performance in a much smaller case.

Not a gun writer.

The 6.8SPC was kind of a passing fancy as far as the military is concerned. They have gone in other directions.

You are looking for a 6.8 Creedmoor or a 6.8 PRC. Both are so close to existing cartridges that they are probably not going to happen. They are bracketed closely by the 6.5 Creedmoor and the 6.8 Western.
I would just do a 6.8 western and handload it to the velocity you want. You are hoping for a new unanounced military 6.8 that has standard short action dimensions and pressures and is reloadable.

Looking at the specs on the new military round,that is unlikely to occur.

.270 Titus.

NULA will do an ultra-light 6.8 SPC in their Model 20 action. The very mild recoil of the 6,8 SPC would work well in a 6 lb rifle. But you need the Spec II chamber or DMR chamber, not the original SAAMI chamber so you can get decent velocities.

Longer throat?

Longer throats yes, but also the cone angle was wrong on the original SAAMI chamber. It was too sharp and was catching on the projectiles. The Spec II chamber has a marginally wider free-bore, the DMR chamber is designed for accuracy and corrected the cone angle without having the wider free-bore. The Spec II chamber changed the cone angle as well. With the longer free-bore, you need a magazine with an internal length of 2.5 inches so you can seat out further and add more powder to get the velocities over 2800fps with the 110 grain Accubond and TSX.

Before the quick twist bullets came along in 25 and 27 caliber, it made sense to design SA cartridges around the standard weight bullets.

Witness the 25x284 and various 25-08 and 27-08 std and improved cats.

The newer longer bullets change things dramatically.

27 Nosler might be the iconic big 27 that fits in a 3.34” magazine.

As it and the 6.8 Western thrive in the marketplace, will drive more development of LR 27 bullets.

Commercial outfit would have to be insane to introduce a short 308 based 6.8; when the next day or year the Army might select either Sig's or True Velocity's 6.8 cartridge as the official cartridge of Uncle Sam. Sig has the 6.8 Fury ammo listed on its website, so would assume it will be out some time this quarter or next. True Velocity was just on TFB podcast, they said Knight and DD would be offering their cartridge.

What an idea or why not satisfy ourselves with any of the cartridges designed before 1945?

You can buy 277 sig fury ammo. They have a 150 gr hybrid case / high pressure option and a 135gr ball option that is full brass case. However the only rifles I have seen for sale are the spear/semi auto deal and they are something like 20k+ on gunbroker. Not seen the promised cross in 277 yet

Are you really going to get the rifle you want anyway if these new .277 cartridges become readily available? You can get a Remington 700 short action which can allow a COAL greater than 3" with an extended magazine which is only needed with the very long projectiles, or use a Winchester Model 70 CRF short action (again, more than 3"), build it the way you want, buy a .270 Redding reamer, .270 Redding dies from Redding, use cheap and readily available .243 brass to form the cases. if you want to use heavy high bc projectiles get a 1 in 8 twist, if you want to use 130s or 140s just get a 1 in 10 twist barrel. You will get just over 3000 fps with the 130s and about 50fps less with the 140s. Yes, it costs more, but you get what you want.

Are you looking for something that will shoot long high BC bullets?
The hard question, for me was, how far am I going to shoot at game? How far can I practice at? Do you want a thousand yard target gun?
Get what checks your boxes. The 270 WSM works for me. Everything I do is well under 500 yards.
6.8 Western or 27 Nosler have some appeal.
Good luck. Lots of choices. As to the Sig Furry; IDK if it will be a big thing or not. It is definitely different due to the pressures involved, or so I have read.
Looking forward to hearing what you decide and how it works.
