7mm Saum

[G.E.FLACH]

Here is the skinny on the saaum from my perspective.Remington killed the sauum because it would not feed reliably from a 700 none detachable magazine action .The feed rails were inadequate to contain the short fat case ,wsm included . Keep that in mind if you build one.

A 160 accubond approaching 3000 FPS is awesome, never mind the head stamp.

It's been around for almost 20 years... you are saying this like it is new info...

I have had two rifles in 7mm SAUM, and found it to be a well balanced cartridge... but then so are many other 7mm cartridges. I currently shoot, 7X57, 7-08, .280 Rem, 7X64 and 7mm WSM... no SAUM's in the cabinet.

I shoot all those and the SAUM, as well as others. I think it's a great little round. - dan

Impressive case with Max Dangle

Im getting 3030fps out of a 24 inch 1-9 twist Benchmark with my 280 AI using 60.5grs of R26 and 160gr AB, so I figure its just a personal choice as pretty much identical performance

 

[Slimbo]

Great velocity, I’ve been meaning to try RL26. I have lots of 7828 and it works well in my 280ai for about 2950

 

[remington jim]

Yup, one of my favorites, but I currently don't have one... still have brass and dies, so it won't be long... you know how that goes...

I got 2 now ! RJ

Most 7 MM Rem mags do NO better then that with Handloads - and lots less with factory ammo ! RJ

 

[Buckmastr]

The 7 Rem Mag is the best. Belt and all

They will do it with less pressure.

 

[remington jim]

They will do it with less pressure.

and So What ! My 280 AI HVA rifle cases unload Find after being fired at 3000 fps ! I have some Nosler brass with 5 firings on them and the brass is still good ! Needing to be annealed now thou . RJ

The beauty of actually having done things for yourself is knowing when you are being hosed.

Good to see you staying on TRACK here Chucky RJ

I’m just not sure who you are trying to fool? That’s all.

Case capacity:

- .280 AI= 67.9gr
- 7mm SAUM = 72.6gr
- 7mm Rem Mag = 82.0gr

I’m old enough to remember that 82 is more than 68.

Remington developed the saum cartridges with the idea of producing a short, lightweight rifle for hunting. The truth was, more and more people were subscribing to the long-range "hunting" philosophy and they didn't want a short, light, mountain rifle.
The cartridge is a good performer in the "F" class arena and works well for those who use it.
Neither it or the 280AI will match the performance numbers of the 7mm Remington Mag. Loaded to the same pressures, the 7 RM will beat the AI by 150 fps and the saum by about 100. This was true (regarding the AI) forty years ago and it is still true today.
