I'm presently loading match ammo (.223), for my match AR, to shoot the short line (200&300yds.). I'm using new Lapua cases, 77 SMKs, and RL15 powder. I really don't want to weigh charges, but my Dillon measure on my 550, is throwing weight variances with an extreme spread of about .5 grain. I'm purposely keeping the weight away from max, to avoid problems, and weigh every charge for the 600 yd. loads, but I was wondering if you guys would find this acceptable for the short line loads.
