7 SAUM vs 7 WSM

[fatbacks]

Reloading manuals are a good resource even if you don't reload... Hornady one discusses the differences between the two cartridges.

Why are you pulling your current 7wsm barrel? Whats wrong with it?

If considering a SAUM, you may want to also consider a 7 Sherman Short.

There isn't anything wrong with it. Im just running into mag box length issues and long term I plan on having a rig setup to push heavier, longer bullets to hunt elk size game and larger. Probably one of the 30 cal mags. A 7mm SAUM should allow me to push the intermediate weight bullets at a decent velocity out of a 22" tube without having mag box length issues. I would prefer not to run a DBM on a hunting rig. . at least at this point. Per Zermatt, my only option for longer COALs in this action is to go to a DBM.

Sounds like the 7 SAUM is the easy button for your current action. The cheapest option is to not worry about it and seat bullets deeper into the WSM case. Another option is to go with a Sherman SST case which is made specifically for the 2.82” mag length.

If coues deer is all you plan to use this for maybe look at the 6.5 SST with 120-130gr bullets, though a 7 SST would be faster with same weight bullets. Both will be noticeably slower than your wsm. Now a 6.5 Gap 4s or 6.5 SS will get those 120-140 gr bullets fast

Hahahaha, 7mm is way more than you need for lil bitty coues deer. But it is a long range machine.

A 22" with the smaller bullets in SAUM will be plenty fast.

Here is my 7mm 180 at 735 yards. Tore him up. Blew through him, exited his stomach and blew a crater in his leg. The copper was in his leg...

Where you hunting coues?

If you're bored and just want to spend money, I understand. . But unless you can't get the accuracy you think you should because you're jumping too much you're wasting money with a rebarrel. If building from scratch the saum makes sense but your basically moving parallel here. Also chambered in the same length actions the saum can't outrun the wsm. Chop your current barrel and/or have it set back and rethroat with whatever lead you want. I would say take whatever $ you're going to spend on this project and buy components and shoot the shit out of your wsm.

Im partially bored lol and there are a few things I am trying to do simultaneously too. Im going to upgrade barrels and go the CF route. They look badass, work well with larger brakes not to mention the accuracy difference that I should achieve.

Im ok with this being a step sideways and I like tinkering with the stuff. I already had the stock bedded to my action so I don't really want to bail on the platform. Achieving the accuracy with the higher BC bullets out of the WSM required to load them longer than the mag box would allow. The 168gr Berger classic hunters were basically loaded out to full mag box length.

FWIW I had same debate a few months back.

Went WSM with CF barrel off savage action.

I’m happy with my choice. Based on what folks were posting on SAUM velocity I am happy with my bump in performance with the WSM. It’s still shooting half MOA or better so I’m not worried about accuracy.

I like having half dozen fairly easy to find factory rounds if I want to go that route and cheap hornady/Winchester brass. Maybe not as good brass quality as SAUM but cheap and meets my needs.

Agree for your mission either will work well. I like velocity and chose accordingly.

Yeah, muleys will be in the future for this rifle and the flexibility to use on elk too would be nice. Good shot, ill probably pick up some Bergers to give a rip with and see what happens.

I haven't decided what unit to go after yet. My father in law has a place down by Tucson so it will hopefully be in the surrounding units.

If my platform was a savage action the WSM would likely be the best option for me. My action is already bedded and everything just works so well I probably won't mess with it. The only issue is the mag box length, so the SAUM being designed by Remington on their mag box is probably a better option for me. I too will be going the CF barrel route.

 

[crich]

That short neck stuff is a myth, the straight 7 wsm is incredibly accurate and just as easy to tune as a saum.
What effects bullet alignment is crappy case resizing techniques

What would you refer to as bad techniques?

 

[UnckleBob]

What are you planning to shoot which would need a longer bullet?
