7SAUM vs 7PRC....Click before you judge

[Soskop]

The 7 saum is an awesome, dead cartridge with no factory ammo suuport.
The PRC is a well designed cartridge that has some support.

I would say it's dead. There is factory ammo out there.

Thanks!

Thanks!

Definitely not a ton, but some available for sure! It's definitely something you would be better off hand loading for sure

I guess i have to move quickly then , Thanks again.

Ha ha buy some of that gunwerks 7 saum for $175/box.

At some point I will be replacing my tikka 7 mag barrel with either a saum, prc or possibly even 280. I honestly don’t NEED the prc speed. It’s in a Xlr with aics mags.

Is there an actual real world decrease in recoil going with the saum? Now that brass is available for the saum I think that would be enough to win me over.

Planning to shoot 180 elms.

This is where I confuse myself. If the Saaami specs COAL is 2.825" how are guys loading COAL out to 3"+?

I know it's me who is misunderstanding. Trying to plan a reloading system and build a rifle all at the same time has been a bit on my brain hah

To load longer than the typical magazine you need to change something. Option one is to have a gunsmith install a Wyatts box. Depending on gun some can get pretty big and still feed in a short action.

Option 2 build on a xm or long action.

I'm running it in a chassis, so no Wyatt's box, and I'm pretty stuck on the short action.

I think I just need to build it and then measure and see what it can take am without fees issues. Trying to speculate and plan has just gotten me further and further into the weeds

Just measure or ask company what the magazine oal limit is and back off a smidgen. Then pick a bullet, load dummy round, then have you gunsmith build barrel to fir.

It’s all academic… if you reload the SAUM is plenty available. Look at the custom brass makers who barely keep up.

It’s splitting hairs, but the little differences are what we all fret over, lol. I just said to myself “I like short actions, I only want short actions.” So, I sold my 7 REM Mag, but my 7 SS wasn’t any better on the ballistics. The buddy who bought it is happy and still shooting tiny groups. If he draws a tag he will kill something with it.

Consider a 7 Sherman Short, more case capacity than a SAUM but shoulder pushed back to run the 180 VLD in an AICS magazine. Sherman blew out the case taper and increased shoulder to 40.

I run the 180 VLD at 3025 in a 26” barrel. You get a little more speed than the saum.

If you run the lighter bullets with more velocity, you get the benefits inside reasonable hunting distances.

Like has been said above, 7 mags, even short ones, launching bullets at speeds and ballistics that most shouldn’t go beyond. Use a good bullet and you’ll slay. The 280 ai nearly matches the ballistics out to most hunting distances.

When I started, I thought I needed a bigger bullet.

It was more than I needed so I dropped to a 25 SST shooting 133 out of a 21” barrel at 3100 fps. My next rifle will be a 22 creed…

Thank you for that! I think I have been over planning and trying to build something that will way exceed my desires terminal metrics. I honestly would prob ever hunt with a 180. My thought was to make sure I had the option to Of I wanted to, but I think running the 7 SAUM on a short action just makes that incredibly challenging

Those are quite pricey now.

I really like my 7saum. It pushes 180 eldms at 2760, no pressure. My 12 year old daughter has killed 4 animals with it and my wife has killed a pile of stuff. It’s a travesty that Remington put their name on it. The 7PRC with hand loads will outrun it, but I think the 7saum really hits the sweet spot for a suppressed magnum in 284.

Nice one!

Yeah, that’s why Sherman pushed the shoulder back.

Honestly, I encourage anyone who asks me in person to run a 6.5 or .25 short mag.

It is the bullet that does the work, and the 133 Berger is as devestating as the 180. And, the 133 does the same thing out of a shorter barrel.

My rifle shot a Coues at 710 yards with a 180, and that’s when I decided to go to .25 as soon as Berger released the 133…

 

[hereinaz]

Guess whether this is a Berger 180 VLD or a 133 EH.

Range was 325 yards on a Coues buck….

The Berger 180 VLD would be my guess.

 

[hereinaz]

The Berger 180 VLD would be my guess.

When I saw my .25, I thought well, I definitely have the same confidence killing anything my 7 could…

Spoiler, it’s the 133.

The Berger bullets are so devastating and I can’t really tell a difference between the 133 and 180.

It’s why I am building a 22 creed for deer.

But, this is a 7mm thread. I love it too. It will absolutely hammer.

I have never use them before, just don't have much info on them but seeing such performance. they are a must try now.

I have seen the same sort of thing with ELDx. There just isn’t a whole lot of difference between the .25 cal bullets and the 7mm.

So, staying on point, the 162 ELDx of OP are gonna work out of a shorter 7mm barrel. Velocity is king in the first 400-600 yards. Past that the higher BC starts to matter of the 175/180 class.

But, at the point the BC starts to matter, you are beyond the reasonable hunting distance without exceptional skill and well dialed rifle system.

For me, seeing bullet performance, that’s why I dropped caliber and gained velocity.

The same thing applies to just dropping some weight in the same caliber. You won’t tell the difference on game between a 7mm 180 VLD 94 168 VLD. If the 168 checks all the other boxes, run it.

My choice for dropping caliber gives me speed and BC. That combination gives me the long range advantage past 500, which I want and practice for.

I’m sorry to be a nag, but nobody has answered my question. Will you have problems running a 7 Saum in a long action?
