My Roberts has a 2.95" COAL throat for the TTSX 100 gr. Could be 3" or better for the more extreme ogive bullets like VLD's, etc. Would have to check my records.

Nothing "intermediate" about 3.33", that's LA territory. Those 160's are barely in the neck.

That gives more powder room, more options for faster loads in a strong action like the CZ.

Maybe not as crazy as these Dennis Hall loads, but still more powder room.
