If I could not get N133 what powders would be the next best selection in a 6 ppc. awile back IMR xbr 8208 was suppose be good. Now its LT-32. Benchmark was also suppose to do ok along with H322. If you could grade them accordingly on a scale of say 1 to 10 with 1 being the best I would appreciate it. With the availability issues I need to have a back up plan.Thanks, Bruce
