[QUOTE="rharfo, post: 1236587, member: 50031"] Preparing for a upcoming hunt. Shooting out to 400 yards and my dope is off- shooting several inches high. I chrono rounds that I've been shooting and they are 100 feet per second faster then the loads I set zero with. So three batches of brass two are fire formed Rem, third is fire formed Nosler. One batch of Rem is 100 fps faster. Why? If all things equal how? Using IMR 4831 60.0 grains. 140 Accubond Fed 210 primer. Soooo if I shoot up my original zeroed loads will the next batch shoot same speed? I leave in 4 weeks! Never had such a big change in speed like this before.... [/QUOTE]
