[QUOTE="918v, post: 1081243, member: 84964"] I have been using it in my TRG22 308 26" for a couple of months. I settled on (don't laugh) 41.66grs under a 175 SMK in a FC case. It does 2625 FPS with an ES of 10. Been using BR-2 primers, 210's and 200's. My lot of 200's makes 20 FPS less velocity. Accuracy wise, I can put three through the same hole at 100 yards, but then satan interferes and I get a flier or two. But it always shoots .5" or less. To compare it with 4064, I get similar velocities with 41.75grs of 4064. The difference is 4166 is a double base powder and 4064 is single base. 4166 is much cleaner and does not leave 10% of the carbon that 4064 does. [/QUOTE]
