I use 2.8 grains of titegroup with a missouri bullet 180 gr lead truncated cone. They run 700 fps out of a 5 inch barrel. They are slow and don't burn the lube but they seal just fine and don't lead at all. I have shot 800 of these before cleaning my gun and have never had any problems this load burns fairly clean but not as clean as clays. They do smoke a little. This is a very soft shooting load I run them through an m&p pro with a 11 lb spring and can ring steel animals everytime at fifty yards if I take my time and about half the time at 100 and im just an average shot. These will shoot 1" ten shot holes off the bench at 25 yards. The only load I use for in a 40. BTW my m&p has an apex trigger with the competition springs and it breaks at 2.2 lbs consistently and adjustable dawson sights. That does make the long range shooting easier.
