[QUOTE="BrentM, post: 1813472, member: 61747"] Me, I set my bullet 10-20 off the lands and work up the loads doing a velocity ladder looking a stabile and hopefully wide velocity node. Usually shooting at 300-500. Once I hone in on the upper charge weight with stabile velocity I shoot for accuracy test and verify low sd/es. If accuracy is not great I test seating depth. Again 300-500. This method has been working well for me. Just to throw this out there....100 yard groups don't mean anything to me other than for zeroing. I have had many many bughole groups with horrible sd. I have also had outstanding 400-500 yard groups with horrible es. I shot a sub moa group with 6 charge weights and 130 plus es working on loads in my 6.5 PRC. I am of the opinion and experience that without low sd/es for long range shooting you don't have a good load. You may have load tuned for a specific range but not for a wide variety of ranges, especially when you get to 1k and beyond. [/QUOTE]
