I bought a pack of the nitro tri plex loads and shot them out of my 11-87 SPT with 5 different chokes and they shot no better than any of the other good loads that I patterned.... If your going to go the nitro route you miles well get the Rhino choke also....

Dude you can spend a !@#$ load of money trying to get the perfect pattern...

How many vital hits are you getting at 40 yards???
