messin around with my CZ 527V 9 twist 223 and the 69 SMK workin backwards to a nice quiet subsonic load,,,started at 12 grs as I have done this before but cant find my book with my notes on ,,at 12 grs I was still above 2,000 fps but for five rounds the chronie was very constant with ES in the single digits and SD was 3,,may have to check that again and shoot for accuracy,,I wont quote my final exact load but wound up at 1,060 fps avg with the fastest at 1071 and 5 rounds at 100 yards just over an inch,I may take the plunge and send in my 200$

fun fun
