Been 16 months but worth the wait!

375 Viersco mag 375 VM2 short neck proprietary cartridge. One of a kind.

The 375 Viersco Magnum was developed for the super long range" Hard Target Interdiction" rifles.

Ballistics:
33.5" barrel test

375gn Cutting Edge bullet
H-BMG 50 powder
3300 fps
9100 Foot pounds at the muzzle

3000 yds super sonic
------------------------------------

350gn Predator solid
H-BMG50
3450 fps


Here she is



Custom action from Dave Viers, 34" Lilja barrel 1"9 twist to facilitate up to 450 gr 375 bullets. Manners stock. etc.

The cartridge compared to 338 RUM and 280 AI---180 gr capacity





Theoretically it will launch 260 accubonds at 4000 fps but it will not stabilize them.

Here is the webpage.....Yes that is my rifle on it!!!

Fotis, I'd pay money to watch you swat an elk with that one.

That would be fun huh??

How many shots before the barrel burns out?

With care, more than a 243. I think I got 1100 (would have to go out and check for actual round count)out of a 338/408CT so he should get significantly more with a bigger .375 hole.

I would have thought that the 375 version would have run a little faster powder than H50. Most of the loading I did for a 375 Chey Tac was with retumbo, but I did not play with it a whole bunch.

I agree with you Eddy. H50 bmg works better because of the added case capacity

I almost did a 375 improved version of the Cheytac when I rebarreled but stayed with the 338 version because I already had a reamer.
Will be looking for some long range group pics.

WOW !!

Scoped

Go shoot it already. That first round is a life changer
It will not kick but the concussion is like a grenade just went off, really cool, you get used to it and will love it.

I Love it.

Wow! That should work.

Bb

That is one of the coolest caliber/rifle I've ever seen!


Roy

Get some video shooting it over a bed of popcorn. That would be spectacular!!!

Concussion.. no doubt!

That is a badass setup. Congrats!

Eric

Whoaaa! That will surely bring the heat.

What a monster!

That thing should be fun!

I didn't know the dino's ever made it off Jurassic Park Island??



That's a beast...and I am jealous!

Fotis I would like to see that in action...

scope holding up?

Damn that rifle is cool. mtmuley

That's one bad mofo rig!

Fotis, could i buy a dummy round from you?

With the balls hanging off that thing, it's a heck of a lot more like a "HE" than a she....

LOL!

Like the truck nuts, we need some gun nutz...

Whatever brand of scope you pick...print off a few mailing labels to the service dept today...you're gonna need em!

spoken like a true odumber supporter......

I scoped it with a SWFA 5.5x20x50mm Super Sniper HD.

Fotis, are you sure that's a girl-rifle? Appears to be more boy, as in he.

Holey Moley.
Makes a .338 Lapua look like a gopher rifle.
You are usually good for a rifle with a WOW factor, this one has all of that and then some.
I might be able to hear it from my place.
Nice rifle POP.

Magnum Muscle Brake?

Sweet Rig. Need to see some 600 yard targets.

Pure prairie dog death.....now that's a rifle. Really nice.

There's another one right over there!

Where?!

Next to the crater where the last one was...!

Amazing...wonder what 1000yd accuracy is like?

I will initiate break in procedures soon. After elk I guess.

Dave Viers (the builder) suggested this

Load info
OAL 350 smk to touch lands 4.140"
153gns H BMG50

I am thinking along the lines of long range cape buffalo hunting

Good grief, you should call that thing the "375 Super Beast".

that put a smile on my face

Lets see some pictures

Fo-Tee

Is PETA giving Elk Kevlar vests in Montana or something?

I thought. 338 Laupa would have been big enough.

Not a hunting firearm really. BTW I am in Wyoming.

wolf rifle when you get that monster running I would like to drive over and see you shoot it!

ya but you could shoot an elk in montana with it lol

Make sure you have a good hiding place for it when the zombies come. Better yet, be perched on a ridge with it at 2000 yds. :0

And the advantage over a 50 Bmg is?

Just think if there is a battleship between you and the deer, you got him.

On the serious side what are the BC's on those 350's

IIRC the 50's where 600 grain A-Max to get a decent BC, and a 30 cal is 210's

350 Sierra .805
414 GS Custom 1.25

Both G1

Too cool Fotis...my billfold quivers just think about feeding that....

My 338 edge just crawled under the bed in my man cave

Fotis you could reach a Krikri out on Dia from the beach with that!

LOL

What does she weight?

Those numbers are so impressive I had to think about them to get them in my head. What velocity can you achieve with that 414?

Good god, Fotis...that thing is insane!

Can't wait to see some target pics and data...

PS I live in Idaho. If I have a rifle malfunction during hunting season, can I tweet you GPS coordinates and have you shoot my elk from your yard? Thanks...

Quote from Dave Viers

You been there???? WOW!!!!!!!



She weighs 19.4 lbs loaded and ready to shoot.
Scope, rings and 40 MOA Base.

375 VM2 416 WBY 338 RUM 280 AI

Need Ballistic data and videos now

800 rounds and you won't be able to hit your azz with it! You can't stick that much powder into a case and blow it down the bore without throat erosion!! Get back to me when it 'goes' so I can say "I told ya so!"

You may be speaking too early. There could be diameter to consider when you think about the amount of powder. I don't have any idea, just thinking out loud.

Oh Boy! Now that's a good looking toy there, Fortis! Congrats!

We were there together, Say Hi to Koola for me.

OH OK I got it now.... Mike right?

2115th Comm Squadron....

Bingo

So are you retired yet?

If I go past you in WY to shoot speed goats I'll try to stop by.

Sure thing!

Yup retired. Flying Satellites for Dish Network (Echostar)

I'd like to shoot that here in pa on the first morning of buck season.

Awesome!

I'm kinda thinkin that anyone building a rifle like this does not really give a big rats azz if he has to re-barrel at 500 - 800 rounds.

That, and throat life seems to be determined more by bore size vs. case capacity ratio, rather than how much powder is being used....

yup

As useless as tits on a boar hog!!

Maybe, but WAY more fun. mtmuley

This.

hell, I'll bring the refreshments and the Nachos and the grill to BBQ some elk steaks at the campfire...

Anyone who builds a rifle like this knows the barrel won't last forever and always has another on order. Just part of owning a toaster re: all the F-Class open shooters.

I just keep vizulizing those SWFA turrets popping off the first time this BEAST roars.

Can't wait for the first range report

As soon as hunting is done.

PS Hope you're wrong about the turrets!

Very sweet rig.

Sounds like sombody's jealous??

doubt that

you win that is the ultimate LR rig

Bring that thing up to the Canadian NWT and shot a Hog in Russia...LOL

A bit undergunned for elk.
Should be just right for PDs and antelope.

Man! I have so many PD guns and all my spots got poisoned. I would kill to get some more!

Don't be that jealous now. And a TRUE rifleman, would find use for it for sure. I know I could easily.

It may be true.
That I would play with tits on a boar hog.

Kind of like, it feels so good when you quit?

I have been down the road of a throat burner before and was frustrated by loosing a barrel at 800 rounds, not so much on the cost, just the pain of shipping, time away etc. Would melonite or similar salt bath help mitigate the erosion and extend the throat life?
