I hadn't been able to find Extralite, which is my favorite powder for low pressure 12ga loads--albeit not down in the 4K psi range--for some time. Recently picked up an 8# jug. Couple reasons I like it: I tried both 700X and American Select, and while both will give low pressures, the loads call for around 20% more powder (17 grains AS vs the 14.2 XL I use in my loads) per shell. And Extra-Lite is extremely clean-burning. Shot a couple rounds of skeet the other day, looked down my barrels. They were almost as free of powder as if I hadn't fired the gun.
