Home Forums Hunting & Shooting Hunting Rifles 8mm rem mag

Anybody have one built?

I have a Winchester 70 stainless/synthetic in .375hh thats not getting any use.

Thinkin about turning it into something cool.

8mm rem mag, maybe a .358 STA. Would go with a decent synthetic stock, stainless barrel.

Do I need? Hell no.


Any experiences with the Big 8?

I vote 358

If you can stand to give up a little bit of performance, perhaps consider the 325WSM? Otherwise, if you want to go bad (in the good way), perhaps a 33 Nosler or, if you were really wanting something unique that shoots powerful, expensive ammo maybe a 33 Nosler necked to 8mm. I myself have pondered this particular cartridge and what it would do... probably ~150+ fps over the 325.

Good evening sir, I hope the day's been a good one for you and this finds you well.

Going off of an increasingly foggy memory bank here, a shooting buddy had a Remington 700 Classic back when they brought out a different cartridge every year in the Classic. Unless I'm way off in my timeline, I want to say it was the late '80's or possibly the early '90's.

We chronographed a few different loads with it and it was fully capable of reaching the velocities stated in the manuals and gave decent accuracy as well.

The biggest issue he had with it was that there weren't a lot of different bullet choices back then and with things the way they are, it might be better or worse now, I'm not sure.

Sorry I can't give you better and more up to date information, but good luck with the build whichever way you decide.

Another 358 vote. The barrel will last longer than the STW.

I'm fond of the 8mm Rem Mag largely because it is one sexy looking round. I never got one and they are few and far between over here now. I ended up getting a 325WSM though, and the ballistics aren't too far behind the Rem. I haven't shot anything that bleeds with it yet.

Thanks for the replies so far!

Its either gonna be a big 8 or a 358sta.

I definitely need one to shoot 140 pound deer at 125 yds LOL

I am leaning 8mm just for the cool factor.

Barrel maker recommendation?

I worked with a friends 700 bdl in the mid 90's recoil wise they are very abusive. A good limbsaver or R3 pad would have worked wonders. Finally got 200 npt's grouping under an 1 1/4" and told him it was ready to go. Rumor back then was the 185 grain Rem Corelokt did not hold up well at 3000 fps +. A FEW YEARS BACK I found a couple of 100 ct bags of them. I bought them for my 8×57. Mb

I got over my desire to burn 80+ grains of powder at a lick. Now when I want "cool factor" and something everyone else at the camp doesn't shoot I bring my 700 Classic in 250 Savage.

If you have a 375H&H and want something different - do you have a 300H&H? A switch barrel 300/375H&H would be cool.
Otherwise neck that 8mm brass down and get a 7STW!

I owned a Sako 75 Stainless/Synthetic in 7STW.

Cool gun

Shot a few deer with it

Moved on to other things.



With the 8mm am intrigued by the 220 Sierra game king and also the 220 Swift A Frame.

Those along with the Woodleigh 220 bullet were the ones that ended up being interesting. The disappointing thing was how much better .338 was in terms of bullets.

In .358 the only bullet that looks interesting is the partition.

Of the two I'd go 8mm.

I have a couple full boxes of original 8mm Remington Mag ammo.

8 mag all the way!

Several years ago a good buddy of mine inherited an old 700 bdl 8mm mag. I had always wanted one but never could find one. I ordered dies, brass and bullets and we loaded ammo for his rifle. 180 tsx and H4350 were wicked killers. He used it in white tails and a few tx exotics. A few years later I found one and also shot 180TSX. It hits deer HARD. It does have some recoil but I’m not particularly recoil sensitive and it never bothered me even off the bench. 3-4 years ago I took it to Africa. Eland we’re on the list so I decided to load 200TSX for the trip. My PH saw the rather long case and was a bit nervous, afraid that I’d be more afraid of the rifle than the game we were hunting. I shot a few zebra, a kudu and an eland among other game. After seeing how well a properly aimed 8mag killed game he offered to let me go after a Cape buffalo another hunter had wounded but we never got the opportunity. I have no doubt the cartridge and bullet were up to the task. Both of our rifles shoot extremely well, recoil isn’t as bad as most say it is and a well constructed well aimed 8mm bullet is an extremely effective killer. I’m all in for the 8 mag. Good luck on your rifle.

I’d be tempted by the 300 H&H as well. Maybe 300 WBY or a 300 Jarrett if I had to be different.

.358 Norma for hunting.

One of the big .33s for carrying the mail downrange.

If it were mine, I’d cobble together some tricky reduced loads using cast or .375 Win bullets and terrorize the local whitetails.

If it was me I would leave it alone. The 375 H&H is very versatile. If you must change it I say go big. 416 Rem Mag or 458 Lott.

Well I didn't see page 2. We will see what others think.

I like the way you think.

I had 3 built and one factory. That was back in the day where the only real option for premium bullets was a 200 grain partition. As for high ballistic coefficient bullets was the 220 Sierra game King. Today there's a plethora of premium bullets that can withstand this kind of power on game. I had great luck with reloader 22 reloader 25 and H 4831 nowadays I would add reloader 26 to the mix

Well then, optimum loads for the 8 R M is not your cup of tea.
It will be in the neighborhood of 80 or 80+ grains of powder to push 200--220 gr bullets 3000--3100 fps.
Ask JRS.

I've had one a long time and there are a few of us here who own or owned them.
From personal experience MY BDL 8 RM hurts LESS than shooting a Ruger 77 OG tanger in 338 WM.
Don't believe me simply try and compare them.

You'll probably be happier shooting "The Man Bun" or 250 Savage or 223 Rem.
