Shorty 7SAUM

[Bater]

I have an 18” suppressed 7SAUM being put together for elk/muley backpack hunts. It’ll be a long bolt stop and mag T3x sitting in a MDT HNT26 folder. Load work up will focus on 160 class Eldx, Eldm, Bergers and TGK’s. Would also consider 180 Eldm/Hybrids if I thought I’d have enough steam to push em. Only interested in temp stable powders.

For those that have done a shorter SAUM, what did you run? What speeds were you able to push the 160s?

I don’t know if it’s considered all that short but I have a long action origin with a 22’ bartlien cut with a longer freebore. 180 Berger hybrid, ADG brass, 64 gns of h1k 2900 fps. Primers look good no visual signs of pressure. Shoots clover leafs. 7 saum with 180 hybrids on the left 6.5 prc with 156 eol on the right

Nice looking set up! The one thing keeping me away from a 22” barrel is my plan to use a suppressor. Have you found that set up too long? This will be open country deer/elk.

I definitely wouldn’t go longer. I only run suppressed. I feel like it’s still plenty handy with my tbac dominus. I’m doing range work with my Magnus RR. I definitely think 4’ vs 100 fps is worth the trade off but I hunt out west and not out of a blind or thick cover.

Have a PBB 18" 7 SAUM, SAAMI spec chamber, with 62gr of N560 I'm moving 168 VLDH at around 2850.

I'm just passing 100rnds and hope it speeds up a bit. Also not seeing any pressure signs so I could probably push more, but this makes nice groups

20” Gunwerks Magnus here. Tried the 160 Accubond and RL-23, accuracy was fine but the 145 LRX was way more consistent at 3040 with H4831.

That’s what I needed to see, for me 2850 would be plenty of speed with the 160 class bullets.

I have a 16" 7rsaum, I'm pushing 150gr eldx at 2815 with H4831sc. Tried varget and h4350 and they were about 25-50fps slower.

Great info, I’ve thought about running a 150 as well.

22" long action Tikka and i've really only shot 175-180s in it but low 2800s over H4831 or H1000. Also, 145 CEB Lazers over h4350 at about 3050 FPS.

This was the first rifle I hunted with suppressed. 22" plus TBAC u7 was too long for me to want to hunt with. I've moved to mostly smaller cartridges and 18" barrels and haven't shot the 7 much in recent years. It might just become my dedicated "long range" rifle with a can now and not see action in the thick stuff. I bet it behaves nicely with some of the new cans with brakes.

20" with a dominus, 175 EH, 61g n560, medium action, adg @ 2840. 9.5 lbs. shoots really well in all conditions/elevations/temps. Manageable recoil for the awkward positions I find myself in.


Real happy with it, but I'm a tinkerer. Every time I think about testing different bullets or powders for it I'm reminded of profound words of Alan Garner:
