I have been very pleased with 124 grn hollow points from precision delta (copy of hornady XTP) and 7.6 - 7.8 gr of accurate #7. Very clean burning with low flash. I load to 1.045 COL with a fairly heavy crimp. It gets 1230 fps out of my glock 19 with a deviation of 8 fps using mixed range brass. I have been very happy with the load data from the Hornady book.
