I think that TL is concerned about stretching the shortened case near the base, approaching a case separation, if fired with a jacketed bullet and a full load. That seems like a possibility. I presume that the cases have been measured before and after firing with the light loads and the reduction in case length has definitely been verified and all cases determined to have been shortened. However maybe some are and some aren't, requiring that all cases need to be checked for length and segregated. I recently ran a case length check on a high number of '06 cases and what made the job fast and easy was the use of a Wilson Headspace gauge which is actually a case length gauge.

I have loaded a good number of cast bullets in several rifle calibers and have not noticed any potential problems when later switching the cases to jacketed bullets. All of my cast bullet loads are with a max load of Trail Boss powder but they seem fairly potent and probably wouldn't result in a case reduction as reported by TL. About all of the '06 cases, before and after sizing, were within limits except for just a few needing very light trimming.

So if TL's cases continue to be a problem, I would be inclined to measure them all after sizing and not use the shortened cases for full loads.
