I finished fireforming my last 60 rounds of 100, for my 6 Dasher yesterday. Before the session, I put teflon stock tape on the rifle and sprayed the bags with silicone, and had a devil of a time duplicating the wonderful groups I shot last week without the tape. After the first two 10 shot groups, I cranked the side pressure in on my Farley rest with its Edgewood front bag. That helped out quite a bit but I still wound up with double groups, about 1/4 to 3/8 inch apart. Nice small round ones but they were double groups. One note; it was very windy yesterday and I didn't use windflags because I was only fireforming. Wind effect? I somehow doubt it because it would start printing one incredibly nice group with 5 shots, then print 5 more off next to the first. Sometimes they would go back and forth....that would have been wind.
It's way too windy today to even think about starting load development but I'm seriously considering taking the tape off and see how it compares to yesterday. Without the tape, I managed very tiny 10 shot groups that were nice and round. Every bullet just seemed to want to go into the same hole. Yesterday was certainly different and the only change was the stock tape.
Any ideas?
