Hey Dan B,
Loaded up a bunch of the Penn Tcbb's and went testing yesterday.330 grs in the smith 500 42grs of lil gun ,A little hot kept rapping my middle finger on the trigger guard.Also some leading but at 2100fps it is expected,going to back down a grain or to.The 180's in my ruger bisley shot 1' at 25 yards with 15 grs of lilgun 1600fps and were comfortable.I hope to get a pa whitetale with each of these.
