Hey, just had a sour experience at the range. I was shooting my 6.5-284 with 107 grain MK's over loads of Varget ranging from a mid load 44.0 grains to a high of 46.5 grains. OAL was 2.99. To say the least, the groups were horrible and the pressure was so high that I only shot one load(44.0 grains)and decided not to press the issue. I think the pressure was more an issue of me having to cam down on the bullets in the chamber, causing excessive pressure. I'll probably bump back the seating to 2.8 OAL. However, the way that my cousin's 7-08, which was also loaded with varget (139gr SST's over 42.0 grains varget) has me questioning the powder. Groups were abismal, so much so they were not worth measuring. I'm thinking that perhaps temperature may have played an issue. I think it got up to around 5 degrees, possibly 10 while shooting. Do you think this could have adversely effected the powder. I don't know, I'm just at a loss here.
