[QUOTE="Montana'eer, post: 2752305, member: 113417"] My 5R .308 loves 4064 and the 168MK's. I began my load testing looking for accuracy first. In my experience with this rifle and bullet, I found a sweet spot- a wide 43.0-44.0grs of 4064. The best consistent load right at 44gr. I'm using Peterson brass- It's a little crunchy when seating the bullet, lol. So being the geek that I can sometimes be, I've been doing a torture test on the Peterson brass. Same lot of 4064, same lot of old federal primers, same lot MK's, same 12 pieces of brass. Every time I go to the range I've got those loaded. Resize every time, anneal after 3 shots... The most interesting thing I've found? After 10 reloads on the same brass my SD/ES has improved. Not by much but I'm at 10es and SD of 6.86. Those numbers are based on a 10-12 shot string too. Not that I really care so much about it but I was tracking it. It's a 500yd round IMO. Also I did get tighter groups when I loaded .010 from lands, but I installed a Wyatts box, so I load to box length now. It's still a sub-moa shooter, but not bug holes. And frankly steel at 400-500 yds rings with repeatability. Hope you find the load that works for you. I don't stress over it- I just keep loading 44gr 4064 and I haven't moved my seating die one iota. It shoots great. [/QUOTE]
