I was recently looking at ballistics for a new build, and just happen to have access to a pacnor barrel at a great price!
Can any one tell me there experience with this cartridge?
The ballistics look great.
Thank you

It probably deserves more respect than it gets. It's a very unpopular chambering. Nothing wrong with it as far as I know, but the 338 Mag offers still better performance on very large game and costs the same to build. more info here

Given the choice I'd pick the 8mmRM over the .338WM every time.
Great cartridge but it is a full length cartridge and not shortened like the .338WM so you may be limited in action choices.

The 8mm is a hammer. It is the parent case to most (all?) of the Remington Ultra Mag offerings. It does not have a great selection of bullets, but there are getting to be more. As above, it is a full length case, and will outperform the .338WM.

It's not the parent case to the Ultra Mag line - see e.g. the Ross Seyfried story copied on another thread. Before Remington adopted them as factory rounds they were the .30 G&A and .33 G&A, invented, designed and perfected by yours truly. They are based on the .404 Jeffery case and offer more or less 200 fps more velocity than the existing kings of the day. The numbers are impressive; but do they really give you anything that will help you catch your buck? The subject of �energy� is a long-debated one, but rest assured it does not matter at all. It is the parent of the .416 Remington and connected to the STW series. As the ads said at the time more energy than the .338 Win at all but the closest ranges and more energy than the .300 Win Mag at all but the longest ranges and that implies a lot to offer - but not in factory loaded ammunition today. Elmer Keith is reported to have asked "What's it good for?" at the writer's introduction. I've often thought of one but never carried through. If I were debating between a .300 Weatherby and a .340 Weatherby I might split the difference with an 8mm Remington.

I have not worked with an 8mm yet.But I am thoroughly enamored with its baby brother the 7mm STW. And I am just sitting down to do some load work with its big brother the 340 Wea mag.
Like you, the ballistics of the 8mm Rem mag always intrigued me. But bullet choices are somewhat limited. High velocity 8mm cartridges are not very popular, therefor not many different styles of bullets are made for them. Of course, you only need to find one bullet which will meet your requirements.
Good luck with the build.

The case is simply a necked down, blown out 375H&H case,left full length.A friend of mine has hunted with his all over N.america an Africa. I have seen him use it in elk and mule deer over here.It's his favorite all-round caliber with a 200 gr Partition at a hair over 3000 fps, but even he admits that any difference between it and a 300 Weatherby is purely academic.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

Best thing about the 8mm Mag is that it makes avaiable brass for the 30 STW (30-8mm).

It's being built off of a vanguard action (was a .300 weatherby but wanted something a bit unique!)
26" Pacnor number 3
Factory wood stock(decent enough wood!)pillar/glass
Trigger tuned to 3 lbs
Cerecoated action matte black, the barrel is going to be "titanium" coated.
Being built by HB Custom Rifles right down the road from me!

RD: I blew it out to 35 cal....they got a name for that one.... Before Remington decided to go with the Jeffery case for the Ultra Mag's they build a couple of rifles in the custom shop in 30 and 338 off the 8mm Mag case. Little birdy (named Ron Engle) told me so back when I had the 700 APR built by them.

"Good enough" isn't.

The .8mm Remington Magnum was a joint venture between Remington and the Singer sewing machine company with the latter providing the .031 caliber projectiles.
The rifle used a necked down Fireball case to propel a 6 grain bullet at a MV of 4800 fps. The chambering never really caught on as only ball powders were usable, extruded powders being too big to fit individual grains into the mouth of the case.
It did achieve some popularity among indoor mouse hunters as it proved to be very fur friendly to Mus musculus and any tiny holes in walls and moldings caused by overpenetration were rarely noticed by spouses.
Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!

I owned one for several years but ended up giving it to my buddy in Utah for long shots on Elk in the Uintah Mts, if Nosler had the Accubonds available then I would still own it, I still have
a set of Redding dies and some brass I need clean house a bit
