Nice, that’s quite a bit more COAL than I had found researching them, but that was obviously overlooking the oregunsmith metal.Can confirm 2.45” with 77tmk fits in oregunsmith bottom metal. This exceeds my 2.44” at the lands measurement with that bullet in my chamber.
The 2.45” bottom metal dimension will translate to any bullet. My guess is this will allow you to shoot your 75’s, with your chamber being the variable determining velocity and accuracy, not the DBM.
Thanks again.
