Thanks to everyone who has responded to all my various posts, i appreciate it alot, they have been helpful! I will quickly cover the basics,;
I am shooting a 6.5 284 Norma built by Ryan Piearce of Precision Rifles, LLC It is printing now, 1/4 inch 3 shot groups at 100 yrds. I wont have access to longer ranges for another month. My main question deals with extreme spread. I am shooting H4831SC with 52.8 grains. The 140 grain Berger VLD at 10,000ths down from full jam. I have been reloading this ammo as meticulously as possible, weighing out each charge. My extreme spread is 2980, 2957, 2980, 2985, 2963, 2981, 2964. I was puzzled as to why my loads were not more uniform in speed. I got alot of great suggestions from people here. I think I may have one of the answers, but would like a bit of input. One of the things that has puzzled me, is my cartridges vary in how they fit the chamber. I know this, because when I lower the bolt, sometimes it is fairly easy and sometimes it is fairly difficult to close. I think the reason is I have been sizing the body then sizing the neck. I think that this is probably an inconsistent way to size. When I size the neck last, it will probably pull the shoulder forward, on some more than others. I have now been resizing the neck first, then the body, which is giving me a uniform cartridge and the bolt feels identical each time. I will confirm at the range this weekend, but I was just curious if anybody thinks this might be the reason for my extreme spread.
