[QUOTE="C-130 Dude, post: 2779404, member: 122991"] First, with a 1/8 twist, your at the limit of using a 75 or 77 gr bullet. Probably best for 68 or smaller. You said your shots didn't look tumbled. But take note here on barrel twist. There are a multitude of possible powders for 223/556. Look at 8208, varget, benchmark, or similar burn rate. Buy and try several powders. This is sometimes what is required. Stop using various headstamp brass. This will induce variables. Thers nothing wrong with military brass. Just stick with one type. Of course, match brass would be best. You didn't state the details on the barrel. Such as 223, or 556, or a 223 wylde. If you are shooting a 556, the long throat lead will limit your shot grouping size. Expect 3-5 moa or so. 556 is not made for high accuracy. What is the barrel length? If you are trying to get sub moa out of a 10, 14, or 16 inch barrel, good luck. It can be done, but its very time and $$$ consuming. Sometimes this quest can be elusive. The best way to get great moa out of this caliber is to use 223 wylde, 1/7 twist, and 18+ inch barrel. A 416r barrel would be nice too. All this is just my experience and opinion.
