One gentleman told me the bullet has a little line around the bullet for oal length.

Too bad they don't sell the flex tips..........but the standard bullet does work almost as well.

If you can get it up to 1130 fps, see what it does on water jugs or wet packs. This seems to be the minimum for my 9mm pistols for expansion to start.

Good loading.

PS;
in the 3" 9mm finals a XTP and two FTX bullets were in the finals, which shows it is a quality bullet.
