anyone loading the 135 CB in a 300 Blackout in an AR

[DLH]

I am trying to find a load for the 300 BLKout for my Ar.

a local bullet co. is offering a 135 g plain base CB bullet at a good price.

I will only be plinking and informal target shooting

Thanks

With a plain base boolit and that weight, don't think you will get it to run semi auto, but more knowledgeable folks will chime in, I am sure
