Joe,
Yep! All your assumptions are correct. I have my bullets marked, as well as the seater, so the bullet is oriented into the throat as perfectly as possible. Even tho I use one case I also have that marked so it can be oriented in the chamber. This might be over kill, but it makes me happy.
Like you I usually keep track of which shot takes a trip outside the group. In this case it was the 2nd and fourth, respectively. The foulers go onto a separate target and are number to their target so I can see how far out it is from the group and if I need more than one from a clean gun or after changing targets. I do all this on the 6 bull target so it's pretty easy to check things when I want.
I probably should have kept track of the velocity of each flyer to see if it was the high or low MV, but didn't. Something to keep track of tomorrow.
Like you say. It could very well be one of those things, altho as close as the SD's are, I'm tending to think it's either some fault of the load, or me! Dew point was very high today and had to keep dusting the rear bag so the gun wouldn't stick.
Jim,
Now there is an interesting idea. When I proposed this idea of "lube purging" on a BP List a few years back I got laughed at. I pretty well proved to my own satisfaction that this does happen, and like you will leave some lube grooves empty to see what happens.
The problem here tho is that I am bump swaging the bullet and as such if the lube grooves aren't full this will tend to collapse it. I suppose I could try clearing off a groove or two after swaging to see what happens.
Good idea and worth a try. Thanks!
