7 saum

[Watchale]

I’m doing some load development with H4350 in a short action with 180eldm and hybrids. The 180eldm at 53.8 of h4350 is getting me 2790fps right now (almost 150 rounds down the pipe). ES out of a 3 shot group and a 5 shot group is 7fps

Anybody loading the Berger 195's at COAL of 3.3 + in a long action? What speeds are you getting ? Power, barrel length?

I don't think Norma has made Nosler brass for a couple years now. Not since Nosler acquired SSA.

That’s possible a good thing
I haven’t been impressed with Norma brass.

 

[GMZ]

The cases look very similar to me, they are indistinguishable except headstamp. Same shade of brass even the depth of chamfer is the same. I’m not really a fan of either myself give me ADG any day.

 

[Sniperwannabee]

Hopefully it works out that all I could find, and it was limited to one box of 25

 

[Steel head]

It will get you going.

 

[SonoranPrecision]

I’ve got a 22” barrel coming that I plan to use as a dedicated hunting barrel. I’ve got some 162 eldx laying around and a decent amount of H4350. It’s obviously not going to wring out the full potential of the cartridge, but what would be a good starting point?

 

[XTREM HTR16]

hot dam, I got the call from GAP yesterday. new 7 SAUM should be here later next week!

@XTREM HTR16 mind sharing your build details?

Wondering what barrel length you went with, bullets you're wanting to shoot, etc

Thanks!

@PFG sure

What barrel length are you working with?

 

[Sniperwannabee]

FYI
For peeps running 180 berger VLD and RL 26

Called berger for reloading info:

2.825 COAL
57 GN - 2704 MV
60 GN - 2844 MV

He said that is a conservative load

what do you think the upper load would be closer to?

 

[Steel head]

what do you think the upper load would be closer to?

Well not knowing your brass volume I’d certainly run up to 60-60.5 and maybe 61 for 2950 ish.
2950 with 180’s didn’t trash brass at all for me.

3000 is starting to get a bit shifty

I’m running 2880 with 190’s with the same brass from my first barrel.
That was the load you shot on my rifle.

Ok fellas need some advice. My first 7mm ive messed with. Doing a 7 saum on a terminus long action Zeus. Got a bartlein 5r 1-8.25 33 inch blank. Have rl26. H1000. Wana shoot 190 berger lrht or 190 a tip. A tip shows ill need a 1-8 for my altitude of 500 or so. But i think itl b ok with the 1-8.25. Looking for recommendations of coal for both bullets to have smith set the freebore at and what length to do the barrel for optimum speed. 28-32 ? Appreciate any help thanks

 

[Watchale]

What barrel length are you working with?

This load ended up being a little hot lol. But I have a 26” barrel. My barrel has sped up a little too.

The 190LRHT is pretty happy at 3.07-3.1ish inches
Should have plenty neck left but good case capacity.

Digging this up again... anybody played with N565? I have a pile of it, N570, and RL26. 565 has been good to me in the past so that is what I’m trying first. Ran a ladder test to see where i would find pressure. 59-64 grains with 175 Berger and 184 Berger... didn’t get any signs at all. 22” barrel on a loan peak LA, .210 freebore. Figured i would start seeing something around 63 grains... nothing. Loaded 2.400 CBTO. I am sure the barrel will speed up another 70 FPS after break in but i wouldn’t mind knowing where pressure starts.

I didn’t see pressure until maybe 2840 FPS with a fresh long throated 22” hells canyon carbon with h1000 and 175 eldx

For those who have run both the old nosler brass (Norma) and the new nosler. Has there been any significant differences in volume or weight?

 

[TRyanOC]

I found an accurate load using:

Norma brass
Federal 215M
59.5 gr of R26
Berger 180 VLD seated long, bearing surface past SNJ, 2900 FPS
Defiance XM action
25" Bartlein M24 carbon fiber barrel, 1: 8.5 T

I use that extra same charge with Berger 190’s.
Bravo for not running thermonuclear pressures.

Thanks, Steelhead. What velocities are getting with the 190's?

What powder and r u running them long. Some guys claim they seen 3k with 25-26 inch barrels

 

[Steel head]

R26 at 3.07 long.
There’s no way in hell they are getting 3K in a 25-26”barrel without being over pressure and inviting brass and primer drama.
My last barrel is 20 fps faster than my previous one and 2860 I think is a more realistic load for that length.
My new barrel is 30” but it’s too new to get an accurate speed yet.
I’d be plenty happy with 3K.

Kinda what i thought. My is being built now. 32 inch. With coal of 3.175 with 190 a tips. So there at the shoulder kneck junction. Really wana see 3k is the goal. Have rl26. H1000. To try

Does anyone offer a factory match load for 7 SAUM?

Does anyone offer a factory match load for 7 SAUM?

nope

 

[fdkay]

Does anyone offer a factory match load for 7 SAUM?

7mm is one of those bore diameters that are never supported by factory match offerings.
The 7x57 has been around since 1892 and is an excellent cartridge, no match loads
7-08 very similar in performance, very accurate. No match loads.
.280 and .280 AI, the AI approaches 7mm Rem Mag capability. Both very accurate. No match loads.
7mm Rem Mag, the most popular 7 bore there is. Very capable long range round. No match loads and almost universally loaded with lightweight bullets. (most factory loads top out at 150 grains, though there are some outliers)
7 SAUM, I don't think anyone even catalogs ANY factory ammo for it though I could be wrong.
The list goes on.

That's a shame. There are some 7SAUM factory loads but they are all hunting oriented and rather pricey. I just like the idea of a long range 1500-2000 yard caliber in a short action. Reloading wasn't my thing when I had a 650 and it's most certainly not the time to get back into it now lol. I don't want to rely on others to load for me either so I guess I'll let the 7 SAUM ship sail. Perhaps I'll focus on a long action caliber that has factory support like the 300 Norma.

Gunwerks has loaded ammo with 180 eldm and 180VLD

 

[PowellSixO]

I like the lack of factory ammo for the 7 saum. Keeps it kind of special really. Not everyone is capable of having one, due to the inability or unwillingness to reload. I have an appreciation for all cartridges, but the 7 saum is one of my all time favorites.

 

[Army First]

Unknown Munitions is OOS of everything at this time. When it is available they do load 7 SAUM ammo from 180s to 162s in a mix of Berger and Hornady.

It really is an amazing cartridge.
That’s the only reason it’s still alive.
Performance, efficiency and ballistics with 168 to 190’s is hard to beat.

If only someone sold 7 SAUM match loads for a reasonable price.....

I am sure the barrel will speed up another 70 FPS after break in but i wouldn’t mind knowing where pressure starts.

Did you ever continue on this route? I have an 8 twist 7 saum for a long action TL3 on the way. I have quite a bit of n565 and H1000, want to run the 180 eldms 175 EOL’s or the 180 bergers wondering what to start with

 

[ID_Matt]

I started way low and worked up. Probably too low. Started at 57 grains and didn’t see a slightly heavier bolt lift until 67.5 and 2940 FPS with both 175 Berger and 184 Berger. All with N565. Depending on what freebore you go with, my case was dang near full. I think you’d be safe to start at 62 grains.

N565 is almost identical to R26 and R26 is my preferred powder for 180 and above bullets especially in a standard freebore.
In a long action especially with a longer freebore H1000 is absolutely a solid choice as well but you’ll be burning about 4-5 more grains to get similar speeds.

 

[bfk4lyfe]

Can someone tell me what bushing to use with ADG brass? I'd like to set final neck tension with a mandrel, so something a hair undersized would be ideal. Everything is obviously back ordered so no idea where to start.

 

[XTREM HTR16]

My loaded rounds with new ADG brass and 175 Berger or 168 ABLR came in at .3165, so I’m using a .314 bushing.
