[QUOTE="lancetkenyon, post: 2214324, member: 68875"] This. For 300 yards and in, I wouldn’t worry about ES, SD, or even velocity. Just work up an accurate load, zero at 200, and see what your drops are at 300. Done. But, I shoot out to 1400 all the time. Finding a load with low ES/SD is vital at those ranges. Even if not looking for top end speed, you MUST know your speeds for proper shooting solutions. A chronograph is the only way to do this. I have had loads that shoot cloverleafs at 100 with a 50fps ES. Those groups will not stay the same at 1000. 50fps can make a 10" difference or more drop at 1000. Even with relatively high BC bullets. [/QUOTE]
