7mm SAUM Load Data

[Chappy6mm]

I just picked up a Remington 700 SA chambered in 7mm SAUM and wondered if anyone on here could give me a good place to start.

Powders I want to use

H-1000
Retumbo
4350
Reloader 17

I have Nosler 150 gr and Berger 168 classic hunters
Thanks

I'm using 65gr h1000 with a 162 a-max in my Model 7 7SAUM.

I,m using H1000, great powder but is a little bulky so may end up compressed.
I run a slightly compressed load with 63.8grn under 160AB @ 3025fps.
With your Bergers start around 63.5grn and work up to 66grn you'l find a sweet spot there somewhere.

Yes 63 gr of H-1000 is definitely a compressed load.
I don't know how I would get 66 in there and get a bullet seated but the max load showed in one of my manuals is 67. Maybe after these cases are once fired there will be more room.

I also own a Remington 700 in 7mm SAUM. I have used many different powder and loads in this gun and most have shot very well. Right now I am having fun with 180 Bergers, but I have shot the 168's both Bergers and Sierra.

With the 160-180's I am using IMR-7828, in RP cases, and WLRM primers. Example: 160 TSX, 60.5 grains of IMR-7828 produced velocity of 2953 ft/sec

168's 60.0 grains of IMR-7828 gave 2800+ ft/sec, but 59.0 grains was very accurate.

With 140 grain bullets I have used RL-19, and IMR-4350. This is one of the powders you mentioned. However I have not used it with heavier bullets, and I have not used H-1000, or Retumbo, because I got great results with the other powders.

I hope you gun shoots as good as mine. Mine is a factory gun with a Boyd laminate stock that has been bedded and the barrel free floated. A couple of targets that I have shot. The 180's are a 4 shot group and the 168's are 3 shots.

I had a Remington 7 in 7mm SAUM. I shot a lot of 139gr SST with RL-17. For your 150gr Nosler, I think that is the ticket. With the heavier, I used some W780, but did so much hunting on whitetails with lighter bullets, never really settled on something. RL-19 or 22 may be good. Not sure about other powders, doesn't seem to need quiet as slow powders as the std magnums, like 7mm rem mag.

By the end of the year I will have a custom 7mm SAUM. And will do more testing with 160, 162 and/or 168gr bullets.

I've only shot the Bergers

60 gr H4831 w/ the 168's
58 gr H4831 w/ 180 Bergers
and Fed 210 primers

in a custom it'll shoot both loads in the .3's.

In my 24" barreled 7saum:

Either Rem or Norma 7mm SAUM brass

162 Amax / H4831 @ 60.5 grs mild load 2850 fps
168 VLD / H4350 @ 58.4grs. Max load 2980 fps

My current load is 180 Hybrids / Retumbo @ 65.9grs 2900 fps.

Absolutely.
Manual say coal 2.825 and max load 67grn. Can't see how you could run that load.
Off top of my head think my coal is 2.930 and still crunches when seating bullets.
