Weird ProChrono Readings
I wasted a couple of hours this afternoon trying to get some 95 gr. Ballistic Tips to shoot in my 6-284. I found a decent load but it was right at 3200 fps, I had hoped for more. Anyway, I am using a ProChrono that is about 6 months old and I noticed I keep getting readings of exactly the same fps. in different strings. For example, at 50.5 grains of RL-22 I had 3341, 3410, 3333, 3350, and 3367. At 51 grains I had 3341, 3367, 3375, 3392, and 3410. And finally, 51.5 grains yielded 3410, 3401, 3375, 3385, and 3375. The constant repeating has me baffled but I never had a missed reading. If you notice I have a 3410 at each of the powder weights and three readins of 3375. My other chronograph is an old Chrony that i could compare velocities with but I am tired of burning up barrels looking for a bullet that will expand at low velocities and still stay together in flight. Has anyone experienced this??
