RL26 in a 7mm SAUM with 180gn Projectiles

[Singo85]

Hi,
Looking to try rl26 in my saum.

It is a 32" 8.5t Bartlin in a Barnard Action.

I am looking for a starting point for rl26 behind a 180gn hybrid.

Thanks
Mick

I don't know about the 7 RSAUM specifically, but I've been reading about guys running RL26 in a 7mm Sherman Short Magnum from hunting barrels (23-26") and getting some crazy velocities. I'd imagine it would work equally well in the RSAUM.

I just looked in Quickload using my current 7 SAUM parameters, haven't used it myself. Quickload says 60.0gns will be around 58000psi and 2980 fps. Quickload is not always super accurate without fudging some figures but will give you an idea.

Hi guys. I am the Developer of the Sherman cartridges. 60 grs of RL26 behind a 180 sounds about right for 2980' in the Saum.
