I am load developing, and on my third session, I noticed my groups open up significantly (.4 to .7 MOA to 1.5 MOA) at 200 yards. I did three things different, and I'm not sure which could have affected the accuracy or all of them.
1) Gave the barrel a thorough cleaning. Then had about 7 fouling shots
2) A small amount of the powder spilled on the work surface. I figured the surface was quite clean and the powder should be ok so I scooped it up with sheet of paper and used it.
3) Some of the powder was trickled into the pan with my fingers. I always use an empty shell to do this, but didn't for some of these loadings
I'm guessing that spilled powder is for fertilizer and you should not get your hand oils on the powder as well. Beginner's error?
