300 Blackout and sm mag rifle primers

[D2x shooter]

Has anyone tried loading 300 Blackout subsonic rounds using small rifle magnum primers?
Thank you, Dale

Yes. Works fine.

I use them for both subsonic, and supersonic. Both suppressed and not suppressed. I use Wolf SRM primers. Same primers I use in my SR Benchrest calibers.

I believe Hodgdon specs SRM primers for all their listed 300BO loads.
