I've been using Winchester Ranger 155Gr JHP (RA40155HP). The winchester site shows 1195 ft/sec at 15 feet and 491 ft-lb. It was tested at the Evan Marshall Stopping power site and penetrated 13.5" and expanded to .62".
Better yet the CDNN Sports web site has it for 12.99 a box of 50 and free freight if you buy a case. I have put 300 rounds thru my PT 140 and totally reliable so far shoots about 2" low at 7 yards. Hope this helps.
