So do you think (or know) that would also weigh a half gram? I figured my little box would not be a good comparison, so I just cut the foil and paper, to see the difference, and was amazed that it was totally different than last night.
Joe, haha! I just read the last couple of pages back and when you came in, I was frustrated no end, and totally misread what you were saying about the chronograph deal. Hahaha!!! I thought you were saying your high dollar RCBS was much better than my little cheap one, that I got an even better deal on, buying second hand, and I snipped at ya. Man, I apologize. When you explained what you meant, I felt like a heal. Especially when you said you were by no means an equipment snob. And, when you said about your stuff coming out of junk piles, it made me cry, at how close we really are. hahahaha. I hope you forgive me.
I thought someone would ask why I posted the yardages on those tests. That was hoping someone would ask and I could get an answer as to why just changing target distance would have any affect on chronograph readings, over a ten minute span. AND, I was hoping someone might mention the ten shot averages on the Paulownia four strings of 10 shots total averaged just 2 feet apart. I did not know that, until I was writing the post. I thought that was pretty good. Then, one ten shot string was way different, and was a different day.
Joe, you mentioned the shade/sunshine deal? I put the shades up and cover them with a white tee shirt, when the sun is overhead. Two reasons. I've taken five minutes between shots before and had it read '26' or '15' or some weird number. I'm thinking it was the limbs and leaves on the tree overhead. Not sure. And, I think it may read better, in the shade. The other day, the sun was in the far South and West, in the late afternoon. Joe, that would be the far North and East, for you. haha...... I parked my tractor and brush hog where the canopy of the tractor was shading the chronograph and it read really good, without an error, for over an hour. Then, I got an error and the next shot read 1550, and the day's highest was like 1300. I looked and the sun was on the back eye. So I moved my tractor till it was shaded again, and it read great, until nearly sundown.
So, have you guys experienced whether the bullet path high or low to the eyes, affects the speed readings?
