May have identified the problem.... my old T-Mag is a "C" style press which may not have sufficient leverage to resize these cases as they are about 0.007 oversize from hot match loads in a gas operated semi-auto. Then there's my choice of lube...works great for routine stuff but may not be the right ticket for this most difficult of full-length resizing jobs.
Anyone think I have the answers?
