[QUOTE="benchracer, post: 1429665, member: 22069"] With an 8 twist, you are fine for just about everything short of the 90's. IMO, 75 AMAX/ELD-M is an excellent choice for .223/5.56 out to 600 yards. You need to measure the distance to the lands with your chosen bullet, so you can figure out preferred seating depth and determine how much case capacity you have to work with. I recommend LC brass (you can buy it already prepped almost anywhere), CCI 450 primers, and IMR 8208 XBR, along with the 75 AMAX. My rifle has a 5.56 chamber (with a long throat) and a 9 twist, 24" barrel. It holds very close to 1/4 MOA vertical out to 500 meters (about 550 yards), launching a 75 AMAX @ 2830ish, using the above components. From there, it is all about reading wind and making the proper corrections. [/QUOTE]
