Is there any one powder good for 223 for 55 to 69 grn bullets and also good in 308 from 150 to 168 grn bullets. Can find powder good in both but not in theese weight range's or am I not understanding it. From what I got good in 223 but only good in 308 from 110 to 125 not so good in heavy 168-180 range what do you use and do you use one powder in both. Thanks Jon
