Had an "interesting" flyer at the CBA Nationals. Actually I had a lot of "flyers" but we won't go there. This one must be telling us something. I was shooting along, satisfied with the building group, when the 9th shot went out left. The prevailing wind was from about 2:00 so that's not too surprising, however what was surprising was the dark hole down low in the orange ring. I didn't even see it until I was checking my targets on the "wailing wall." My tunnel vision didn't even notice the low shot when I was shooting. I didn't see the 7th or 8th shot, but figured it just doubled another hole.
You can see the low flyer is a very dark hole, compared to the rest of the group. Bud Hyett suggested it might be a lube purging flyer. The lube was M&N, no longer available. Years ago Andy Barniskis said it "looked, smelled and tasted like a mix of beeswax and STP oil treatment." That's not what it was, as it went out of production because the maker couldn't get one of the ingredients anymore. The load was a hot one, 28 grs. of RL-7 under a 185 gr. Hoch bullet cast of linotype. Velocity is 1950 fps. Rife a pre-'64 Winchester M-70 in 30-06. I've shot a number of 10-shot groups under 1" with it, so it's a known accurate load, but it was beating me up. I'm not going to shoot it anymore for benchrest!
