Uncle Nick, once again, thanks for the info!
4runnerman: Those loads are straight from Sierra's Edition V, 5th Printing, load manual. When I was testing other 55gr bullets, I did vary the loads by .2gr.
Here's the thread with the details, if you're interested.
I got the .69" group using Midway/Dogtown 55gr FHP FB bullets. I liked the results so much I ordered 1K more, so this will definately become one of my go-to loads. I had ordered a bunch of different bullets, including the V-Max, to see what worked best in my AR. Since everyone is so enamored with the V-Max, and they didnt work as well as I had expected, I'm just trying to see if there's something amiss in what I'm doing - powder, COAL, etc. Looks like I get to keep experimenting.
