25”Great velocity there in a short action! Pretty much on par with 26. What’s your barrel length?

25”Great velocity there in a short action! Pretty much on par with 26. What’s your barrel length?
I shoot mine in a short action. I have to seat 168's deeeeeeeep but found an accuracy node. Push by 4831scAre most shooters using long actions?
What brass are you using? I'm at 58.5 grains R-23 in ADG brass running just under 2,800 in a 22" bartlein. gonna increase the powder charge and see what I can get. ThxI’ve always ran between 60.5-60.9g rl26 with great results. But after some wild velocity drops in 10-20 degree weather I decided to give rl23 a shot on the new barrel
After 50 shots of virgin brass and seating tests, I started at 58.5 and worked to 60.7.
60 grain me 2905 with an es around 5. Shot.343 MOA on a gusty day with wind reading around 23mph. I think I’ll roll with it
ADG brass in 24” barrel. Are you short action or long. On a long with bullets seated longer you should be able to get around 61.5g, I made it to 60.7 with no pressure. And I think you should find accurate node around 2880..the next node seems to be up at 2970 for me but pretty hard on brass so I’m not going to pursue it. I’m shooting 175 elite hunters but they seem to run the same velocity as 180 hybridsWhat brass are you using?

Supposed to be next month. I just did a survey with Lapua and told em 7 Saum is what they need to make. Hopefully others do too!Has ADG 7 SAUM brass came around yet? I wish Lapua or Peterson would offer the 7 SAUM.
180 hybrids and N565 are showing some promise and good sd’s
Any extra hybrids? Lol.Details on rifle and speeds? I have a shitload of both of those.
Its running 2857 average, slower than with RL 26 but I believe i have room to go up.
Any extra hybrids? Lol.
Feel ya there!What barrel length you running?
No can do brother, team never sell these days.
Came across your comment while gathering data for my 7 SAUM build. Your setup sounds very similar to mine. Do you mind me asking what your load data looks like as far as powder, charge weight, primer, brass, seating depth, etc?I'm running them in a Stiller Predator xm action. 24 inch HLR carbon barrel, 8 twist. 2885 fps, SD of around 6 fps. Does everything I need.
62.7 H1000. Fed215m. 190 berger hybrid. Adg brass. Idk what my seating depth is.Came across your comment while gathering data for my 7 SAUM build. Your setup sounds very similar to mine.

speed?62.7 H1000. Fed215m. 190 berger hybrid. Adg brass. Idk what my seating depth is.
I do mine from Norma 300 SAUM brass with no issues and as simple as FL sizing.Anyone made 7 saum from 6.5 saum brass? Usually happens the other way around but desperate times…
When components are scarce I like to tinker. Few pieces of old brass with loose pockets I keep around for dummies or die setting, lubed the necks then ran a 7mm mandrel and seated a 180 VLD. Loaded necks are .311. No crushing or deformation noted.
Function tests fine in my rifle, going to load a few and see how they do just to have the option.

I have a GAP and I just took fired GAP brass and ran it thru the 7 SAUM die. No issues, fired a bunch of them before my new batch of 7 SAUM brass came.Anyone made 7 saum from 6.5 saum brass? Usually happens the other way around but desperate times…

What was the velocityI do half grain increments with 7 SAUM. I hit pressure with 195 Berger, ADG brass, br2, and 61.8 Retumbo. Coal is 3.04 something with .020 jump.
I'm running the same components in a medium action. I ended up using 62.7 H1000. 24 inch 8 twist @ 2885. I moved up in .2 gr increments.Alright. I did some digging but want to verify what I think. Long action 7 saum 190s adg brass and h1000. Start around 60 grains? What do you guys step in? I'm use to alot of short action stuff where I increase in .2 grains but should I move .50 grains at a time?
Thanks everyone
Definitely post up your results. Thinking of doing something like that with the zermatt medium I have laying in the safe...Let‘s find out what this short barrel 7 saum is all about… 18incher… . Loaded 180hyb./H4350 to 57.5gn to start… Hope to get them to 2700 fps…
Update on my 18 inch Saum… 60 rounds down the pipe with 180 hyb/55.8gn H4350/210M/V.Brass. 105 Thou off seated deep into the case. Very short action magazine compatible. Averaging low 2680s now and with very windy conditions the other evening it was very very consistent at 1100 yards.Let‘s find out what this short barrel 7 saum is all about… 18incher… .

Right on. If memory serves I think I had 180 hybrids about 100 thou jump also shooting real well in a 26" barrel from a TL3 and mag fed.Update on my 18 inch Saum… 60 rounds down the pipe with 180 hyb/55.8gn H4350/210M/V.Brass. 105 Thou off seated deep into the case.
