The TCs are SSTs w/ yellow tips.
I've done a little w/ the FPBs and found them to work as well as power belts loading-wise.
Didn't test terminal performance. They sure can't be worse that the 245/45 cal power belts which flattened into nickel-sized pancakes of lead on a smallish buck last fall. Definitely have too choose your shots using those... And that w/ only 100 gr triple-seven!
