About 4+ years ago I was shooting a new 6.5 x 47L to test out seating depth load for 300-600 yard F-Class. I was testing loads out at 600 yards. The first 5 shot group was right at 5/8"!! The next were in the 1.5-2.0+/- or so inches. I was using RL-15, Berger 130VLD's out of a 28" 1-8 / 4 groove conventional Krieger. I have NEVER been able to get anything near 5/8" since. Most groups will be "about" 2", however, getting down to 1.5" on a cloudy, windless day can be done from time to time. Getting below that will be an anomaly when all the stars line up. On a "normal" day, as in some wind and heat waves, staying close to 2 inches would be AWESOME, if done on a "relative" consistent basis. On one occasion, during a 600 yard F-Open match, with excellent conditions, I shot a 200-17X with a .260 Ackley. Nothing "remarkable" about that except, all 17Xs were so tight together that NONE of the pasties even touched the line of the X ring! I have never accomplished that again either. There are times when everything just seems to "come together" and wonderful groups can emerge>>>but that is certainly NOT the norm!
