Bob,
Yep, alox will work on the 30-30. I use it for velocities in excess of 2100 fps, although my 30-30 loads generally stay nearer 2000 fps. The Lee push through sizer is good for seating checks, but you must size the entire bullet. I have an RCBS Lube-O-Matic that I mostly use to seat the check, but let the bullets sized as cast. Good-luck
BCB
