Mike,
Several years back I was very interested in the Starfire design as I have a great deal of respect for Tom and I like his designs. I was rather disappointed in the Starfire as in simple testing I have been able to cause it to fail to expand conisistently and easily with Denim, Nylon, and Wool jacket and shirt materials in thin layers.
It fails miserably against Glass, sheet metal, rubber, drywall and wood.
It is fairly accurate in most of my 1911s and my Les Baer SRP will shoot three rounds into .70" @ 25 yards with the Starfire loading.
If we are discussing the disconinued PMC 45B, 230gr JHP loading I have found it to be a pretty "good" load with basic performance slightly above FMJ and below the standard pressure non-serrated Golden Saber loading.
It is still widely available outside of the US and it is probably a fairly popular loading due to it's low price.
One point I should note is that performance seems to increase fairly quickly with the Starfire as velocity increases, in testing from a Marlin camp carbine some years back, I saw a slightly better/different result, I believe that the PMC bullet material is too stiff for the lower velocities.
