My vote would be Nosler 150 gr Ballistic Tip. Great all around hunting /varmint bullet, easy to find, and shoot really well. Not a real high BC projectile, but enough to get the job done.

I found some 140 accubonds at midway so I went that route. Same bc as the 150 ballistic with the advantage of flatter trajectory.
Guys are really liking the ballistic and kill performance of the 168vld hunting bullets though. I may have to fuss with their finicky seating depth but sounds like they are a great option.

Alright I tried some H4831, and Retumbo out with the Berger 180 gr Hybrids. Only test H4831 at 100 yards and getting really good results. Shot some 3 shot groups of H4831 in 60, 60.5, 61, 61.5, 62, and 62.5grs. I'm getting zero pressure signs, no hard bolt lift, flat primers, or ejector marks. I don't get how I'm able to go so high in charge.
I got pretty decent chrony reading with 62grs H4831 .010" off lands ( 2904, 2911,2917); however, next time out I adjusted seating depth deeper .015" &.020" off the lands it dropped to mid 2850's. Could of been bad lighting, who knows.
I did test 4 rounds of Retumbo 63grs-2789 / 64grs- 2867 / 65grs- 2879 / 66grs- 2953. Might load a few and try out.
My combo:
24" LV Criterion barrel 1:9 twist
Berger 180 gr Hybrids
Remington brass / .002" neck tension
CCI-250
COL @ 3.050"
60grs.
60.5
61grs.
61.5 / 62.0 / 62.5 grs.
62grs. Tested bullet seating .015 & .020" off the lands.
Anyways, I plan to shoot H4831 out to 500 yards and see what it prints. Going to load up to 63grs and see what happens.

Would help to know what bullet you're using...
For such a low speed I'd guess 180s

BW, Thanks. I corrected my post.
Cool. Guess I shouldn't say, "such" a low speed cuz that's pretty good for 180s...

Took the 7mm saum out and placed some targets at 518 yards. Loaded up some 180 hybrids, and H4831, H1000, and Retumbo. I have 24" barrel so I figured what the heck and try out some slower powders. Really like the horizontal of H4831, but got one light base case head swipe on 62.5grs.

trail... great shooting! its keep raining here i cant get out n shoot! all my load been waiting.
Thanks man. Post your results when you get a chance. Its fire season here in CA, and I had to drive a little distance to shoot. Man push that rain our way, we need it bad. It's been very dry since May.
Yeah, your testing kinda mirrors mine... H4831 hammers, very consistent on the targets, but the pressure is there and lurking...
Your 66.0gr Retumbo group looks promising, with the exception of one low impact (shooter?). 2894 fps average, 7fps SD/15fps ES. Certainly impressive from 24" short action!
Nice shooting, thanks for posting!
Trailrider121--
did you notice any difference in the felt recoil between the three powders test? One that that jumped out at me with Retumbo was a significantly gentler recoil vs H4831 and H1000...

The low impact could of been me, or not. I switched between h1000 and Retumbo and could of had affected the shots. I shot 3 rounds of each H1000 and Retumbo, and see what it had to offer. Went to go look at target and said wow looking good, so I fired another two rounds of 66gr Retumbo, and one 65.5 H1000. I know I should have not done that better figured what the hell. The first three Retumbo were the two touching and one 1 1/2" low, and the first three H1000 were the lower shots.
My main goal was H4831, and like you said pressure is lurking and really don't want to kill my brass. Yes, their was a big difference in all three powders. H4831 was really snappy, H1000 a little softer recoil, and Retumbo was more of a harder push, with less recoil snap. I see Skyking likes Retumbo; I pm'd him some time ago and he said to try it out. I'm going to test more with Retumbo, seems to be working well, and getting zero pressure issues.

What do you guys think about Norma vs Remington brass? Case volume difference between the two? I weighed a fired Remington 7 saum brass and was 73.9grs of water. Curious to what Norma volume is.

Norma brass is the same as Nosler (Norma is making it for Nosler, Nosler is doing prep on it and packaging it up and selling it under their brand). Anyway, water capacity in fired brass is also a function of chamber size, but with that said, my Nosler 7mm SAUM brass has capacity of 73.3gr.
I prefer the Nosler/Norma brass. Why? Beyond the fact that they are dead nuts consistent piece to piece and the beautiful prep Nosler does, I like the flash holes on the Noslers greatly over the Remingtons. The smaller flash holes on the Nosler/Norma resulted in significantly less peak pressure, so I was able to run the Nosler/Norma loads at 50fps faster than the Remington w/o seeing pressure signs. If you look at the two flash holes, the Remington is visibility bigger. As such, I think Nosler/Normas are worth the premium price, especially if you plan on getting lots of reloads on them. My Noslers have 5+ reloads and going strong.
With that said, the Remington brass shoots great. I did weight sort the entire group and gave away the heavy and light stuff, leaving me with roughly 2/3 of my orginial pieces. With that prep, they shoot every bit as good as the Nosler, expect they are ~75fps slower.
jbailey,
Thanks for the very informative detail regarding the brass. I was under the impression that Remington brass would yield higher velocity. I figured that Nosler / Norma brass is more consistent. Didn't know about the smaller flash hole. Maybe I'll have to try out Norma brass, loaded full of Retumbo, and let it rip.

Bump up this great thread... anyone have any new 7SAUM reloading data to share?
I have been busy with other cartridges, so I have nothing new, but looking to get back into it soon!

On short action 30"barrel oal 2.950-55 norma brass 61gr rl25 3026fps 5 shot group .3moa 520yd .2moa at 410yd 180hybrids.
Hot damn all mighty! That is cooking with some high powered gas! VERY IMPRESSIVE.
I see two related problems with the 180gr Hybrid from a 7 SAUM: produces insatiable desire to hit targets at REALLY LONG RANGES!!! And makes me hate sitting behind a desk all day...
I hope your not saying im pushing to fast.sorry brother english my second language.those groups wete taken 2 diff days.the 410yd was 61.40gr the 520yd was 61gr.when shooting 520 yd i noticed more preasure sign ejector marks and heavy bolt lift it was more humid thst day..this the problem ive been seeing on this powder while doing load dev.some days 61.40 no preasure sign and 61gr quite much sign.
520yd 61gr.. i might play 60.50-60.80gr nxt tym and proly stay still at 2950-2975fps
410 yd 61gr
The square boxes on first target are 1" the last shot at 7oclock i rushed it because started to rain lol.. which i caled
No, I didn't mean to imply anything about the pressure of your load. I just really like the precision you are getting. .3moa at 500+ is darn impressive!!!
Tnx mate.
actualy ive seen guys here shooting better.. ive tried h1000 4831sc but rl25 the only powder not giving me this fps without compressing powder.h1000 as i stated on second page it gave me preasure sign before geting to 2900fos same as 4831 realy bad presure sign only 2875fps.. but this rl25 it gives ramdomly preasure sign on hot and humid day..they all accurate but i might drop few grain on powder charge and try ut againAt 6mmbr i read those competitor geting good result at 2950-2975fps so might try there.hoping slight ehector marks will disapear..by the i way i also triedthat 61.40 that gave good groups at 400yd when shooting that 520yd..gues what i was having ejector marks and random heavy bolt.and a vertical groups..again uts hoter that day than i shot the 410yd.heres a crazy vertical 61.40 520yd.. i just reloaded 15rds 60.60 and 15rds 60.80 i hope this will finalise my loading dev.
Hey Bjay, looks like your getting close, and your shooting some stellar groups. I finally got my rifle back together and went back out to test more on Retumbo powder. I did switch from Remington case to Norma 7 SAUM case. I shot some loads at 200 yards, and 65.0, 65.5, and 66 grs. shared the same poi with 66grs with the better group; however had a flier. So I shot some 65.5grs at 325 yards, conditions were not great but whatever.
H4831 shoots great , slower with speed but its on the edge with pressure, H1000 shot well, but I like Retumbo and is doing well.
All shots fired round robin to make it fair. Shot prone with bipod and rear bag in natural terrain ( which was not the greatest ). I'm on a good node here and it doesn't shift poi much with all seating depth changes.

Great shooting.. tym to hit that mile
Curious, you're obviously packing the case a little more dense with Retumbo, but are you finding that you are getting "tighter" groups with Retumbo over H1000? Any thoughts on temperature sensitivity between the two?
I went with Retumbo just from the testing I did. I don't have much H1000, and let along hard to find. So I didn't really test much H1000, but I'm sure it works well. My thoughts are to fill the case,and get the desired velocity with lower pressure so I don't kill my cases. So far it's doing really great with Retumbo, and yes its a mild compression load. My COAL is 3.040".
I believe both are very good powders for temperature stability. I think either power will work. H4831 gave me weird pressure signs and seems to be hard on my brass. I just shot 8 rounds the other day at 500 yards and got 2904 fps average speed with 18 ES (24" barrel) through my chrony at 12'.

Thank you trailrider121, obviously right now it comes down to getting whatever you can, Hodgdon seems to be out everywhere for their slower powders, same with Alliant. I still have some H4831sc from my 7mm WSM but got strange pressures at different altitudes/temps, now I'm wanting to shoot the heavies in my new 7mm SAUM. I can find Magpro in stock but being a spherical powder I'm concerned it's going to do some funny things when temps change (here at 7500' I can get a 50 degree difference in less than 24 hours). Sounds like Retumbo is the way to go, especially for saving the cases, thank you.

Berger Hybrids shoot lights out at nearly any seating depth, though I have found them to be very accurate .015 off lands
Good to know on the Hybrids as I just bought 500 of them Also, I finally found some RL-25 so for now don't need to be too concerned about alternative powders.

Midway has Nosler 7 SAUM brass in stock-
Nosler Custom Reloading Brass 7mm Remington Short Action Ultra Mag Box
I can't believe the price they are offered at, but if you are made of money and need SAUM brass, here is the best.

These brass made by norma right? I think bullets.com got 7 saum norma brass in stock better price than nosler.. i think noslers askin bit too much

Yes, I'm pretty sure its made by Norma w/ additional step that Nosler weight sorts and preps the necks. I have 100pcs of the Noslers (bought a long time ago before they were this expensive) and they are great. Every piece is nearly exactly the same as the entire lot. But I agree with you that that price is high.
So I got around to shooting my 7SAUM again. The 180 Hybrids and Retumbo still performing great for me. 10" square plate(bullseye is bottom of spray paint 2 1/2"?) at 840 yard, shot prone with bipod and rear bag. First missed the plate by .3 mils, kinda missed judge the wind. Shooting through the canyon is real tricky, gets crazy winds. Wind was blowing to the left 3mph. Made adjustment and hammered the next three rounds. Love this 7saum, and now I found some Retumbo local, its time to shoot it more. Going to find a spot and hopefully get 1200 or so.

I am using Berger 180's, 55.0 RL17 powder, Fed 215M primers, and Rem brass. I am getting 2860 FPS.
Love the "from the field pics"! Makes me wish I was out in the field rather than poking around the house and sitting behind desk... oh well. Nice spot you have there... looks like your group is ~4", so call it 0.5moa, darn nice.
