[QUOTE="JARHEAD1371, post: 639578, member: 12950"] I had some similar issues with my 7SAUM. My advice to you is leave the chrony at home. They aren't nearly accurate enough to pay that close attention to what they spit out. Double check your scope height for your drops, if it's off your velocity will be off as well even with the drops matching. I have my 7SAUM zeroed at 300 yds and I'll find a load that groups the best, then strech it out to 600+. If the load still maintains a good group, it's a keeper. I'll then shoot it out to 1000 yds, gather my data, and imput it into Exbal and have it calculate the velocity. But as long as the load shoots for me, I don't really care how fast it's going. 180 Hybrids 62 gr H4831sc CCI BR2 primers Norma brass 3047 fps My best 3 shot group with this load was .5" @ 604 yds [/QUOTE]
