.308 Long Action.

358LongAction said:
Anyone here done .308 Win, .338 Federal, .358 Win, or .375 Raptor in a max COAL Long Action with a long barrel and compressed loads with slow powder?

2500 FPS seems doable in a .358 Win 340gr.
2500 FPS seems doable In a .338 Federal with 276-300gr.
2475 FPS has already been done with 212gr LRX.

Thoughts?

Concerns?

Prayers?

"Doable"? Maybe, but at what pressure?

I assume that the 2475 fps is in a 308 and is not particularly remarkable, but the 358 Win and 338 Federal results are fantastical.

We are talking no higher then 62k PSi with H1000 and Co...

No higher then 80k PSi with 6.8x51 Fury Cases and a good strong action and barrel like Tikka or Blaser or Sig or Weatherby ect.

However..70k PSi in 6.8's may work.

6.8x51 shall be more common.

Some U.S. guys have the pressure software but you have to pay like 100 bucks a month. I don't have it.
 
I used 208 AMAX in a 308 and achieved around 2450 fps in a 20" barrel. This combination works amazingly well at long distances. It's like the energizer bunny. It starts out slow but just keeps going and going.

Hanging a long, heavy barrel off a long action will impart more torque on longer action rails. A short action will be stiffer and stiffer is always more accurate.

NEIN!!!

Not if you use a tapered 26-27 inch Carbon Fiber Medium Profile match barrel..1 in 10 twist...maybe..have no idea what the twist should be.

Lighter then a 16 inch HBAR or Bull Barrel SPS...probably.
 
my current ELR setup uses some leftover FTR parts and a very old Savage LA in a Choate varmint stock. 30" prefit Shilen Select Match BULL contour, threaded for a big brake. Shooting the 200gr Sierra MKs around 2600fps. Was running Varget but now Viht N150.

Worked great at 1000yds in competition and hammers to 2000yds on rocks and gongs. Starts to get tired by 2300yds but has reached 2600yds.

Single feeding currently but shouldn't be an issue feeding from single stack AICS type 30-06 mags.

Not sure I would bother with a larger diameter bullet as the case volume is going to struggle with more bullet mass.

But have at it... tons of fun

PS, I have yet to see a lathe turned bullet shoot as well/consistently as a quality conventional cup/core match bullet.... certainly has been tried and didn't survive F class competition pressures.

Things are moving quickly now with different casing and bullet options.

.375 EnaBLR smokin' at 3300 fps...ect...in "little" cases. Expensive as heck.

You MAY be able to safely launch 240gr SMKs or 240gr ALCO's at 2500 fps.

.969 b.c. < ALCO.


What's the twist?

Better for 120km/hr 90 degree winds.

I see what's happening. A new member with ideas and an imaginary gun collection proposing absurd loads. We were all new once.

i am admittedly a novice at precision shooting, BUT.

am i wrong in thinking this is master level trolling?

who the F ever contemplated upon the tree of woe, of shooting in 120km/hr winds?

Besides Mel Gibson that is.

Dont waste your time dude, looking over your posts, I can tell.
You're too old for this $hit.

I guess that you would need to shoot competitions that have very open rules. There is a reason ICFRA limits Open F Class calibers to 8mm and no muzzle brakes, and weight limits on rifles.

Other way. 1-9 or 1-8. Heavier the bullet, the faster the twist required. - dan

Okay.

Had a fellow on snipershide.com testing out .338 BLK Fury.

6.8x51mm cut down and expanded to 8.6 BLK.

He was getting some amazing velocity with 210gr TTSX and 160gr TTSX.

I am very confident this project could be a winner with the right application and components.
