Hello Adam;
Here are the three factory expanding rounds that I experimented with......the PMC round didn't give reliable expansion and only clocked out at a little over 1050 fps. The Cor-bons fragmented badly and were quite violent, but they are difficult to come by and somewhat expensive, esp. to preactice with....
So......I carry my piece (Springfield Armory) loaded with the Winchester silvertips. They were pretty uniform in expansion and clocked out at 1250 fps in my gun.
I always thought (and wanted) a Colt combat commander in .38 Super.....thought it would be a great CCW piece. I have this instead.
I also have a handload using Remington's 125 grn GSHP and (IIRC...don't have my load book in front of me) a charge of SR 4756.....it is extremely accurate and expands very well.
HEY!......FOLK'S AT REMINGTON! ARE YAH LISTENING!!!!!!!!!
