Thinking about building a 7 SAUM on a long action for some long range fun. I'm just looking for feedback from guys shooting this caliber. I am leaning towards a 7mm cartridge and this one seems to offer good performance. Thinking of a 26-28" 8 twist barrel to shoot the 180+ class bullets. Open to ideas as this is just the research stage.
7 SAUM shooters?

I like it. Shoot 160 gr bullets mostly. Good cartridge though. - dan
Interesting. Thanks for the info
I've got one getting built by Insite. 26" carbon barrel. Hoping to get the 180 ELDMs to about 2900 but after seeing a few 147 ELDMs explode mid-air this past weekend, I might have to end up using 180 or 190gr Bergers, haha.
What action are you building on? Going to run ADG brass? 1:8 twist. Perhaps i will email those guys and see what a barrel will run me
I'll have to ask Harley again but I think 9 twist. Hardy barrel.
Just building on a Rem 700 SA (with a pinned lug and notched feed ramp) that I already have. Has a 26" Benchmark .308 on it that I'm having cut down to 20" so will be a switch barrel with that and 26" 7 SAUM. Running Bertram brass as I picked up 300 pieces a few years back.
I've seen that one mentioned a few times on the hide. Whats the brass situation like? That one will run heavies in a short action or you still need a long for max performance?
Supposedly you can run heavies in a standard short action, the OAL is a tad shorter then the 7 SAUM. ADG is making brass, but I'm not sure how easy it is to get in Canada.
Interesting. That would save me from having to buy a long action. What about dies?
Again I'm not sure about availability in Canada. The Sherman cartridge company sells dies for their cartridges on their website, I believe they are forster. Whidden will make custom dies off of a reamer print or a loaded round, they are my preference for dies.
Shouldn't be an issue to get dies in Canada, just might take some time.
Heavies in a Short action INVADE the case capacity Badly ! I shoot mostly 160 gr-ers in my R700 & Saum ! I need to get a Wyatt extended mag box and have the action machined ! RJ
This is exactly what the 7 Sherman Short Magnum was designed to solve. So that you can have the ballistics of a 7 SAUM, while keeping it in the realm of standard short actions.
